Hi.

I use the latest Alloy template that bases on CMS 11.12.0. I can log in as an Administrator without any problems. However, if I create new users - they cannot log in. There are no error messages both on UI and in logs.

The issue was reproduced on different computers. 

Hi everyone, we're approaching to a huge upgrade of an EpiServer system that currently runs a 9.7.2 version and we need to migrate it to the latest version. We'd like to know if there is some documentation available about this task (guidelines, best practices, to-to lists) that can lead us in this operation.

Thanks

Hi,

I'm trying to add a metafield to the cls_organization table, by using the MetaFieldBuilder. Now, creating most of the fields works fine, however, I am not able to create a decimal with a specific precision and scale. When I use the CreateDecimal method, a float is created, which is not what I want.

If I add en entry in the [mcmd_MetaFieldType], with name "Decimal" and MCDataType 18, and use the CreateMetaField method instead where I specify "Decimal" as the typeName and pass an AttributeCollection with specific Precision and Scale, it works fine.

What I am wondering is, is this a safe way to achieve the decimal column in the database?

Best regards

I have an EPI find query as below

multisearch = multisearch.Search<GenericPage, SearchHitResult>(s => s
.FilterForVisitor()
.Filter(f => !f.ContentLink.Match(ContentToFilter.ContentLink))
.Skip((page - 1) * pageSize)
.Take(pageSize)
.OrderByDescending(x => x.ArticleDate)

The ContentToFilter is a Page type which I get using content loader as shown below:

_contentLoader.TryGet<IContent>(optionalContent, out var ContentToFilter);

There is a possibility that TryGet will result in null and then the filter line will throw exception. How do I check for null content before applying this filter. 

Hi, I've made a Form container with some text, text area, selection,...and File upload with limit to 20MB. When the form is published and I upload the file it seems okay but when I submit and receive the email confirming the submission which includes the #summary# the file uploaded is not there and when I check the form submissions I cannot find the uploaded file. Any advice?

Hi,

After upating the packages to the latest version and on hosting the solution in IIS Server, I am getting this error .

The private static field EPiServer.Find.LambdaExpressionExtensions._cache keeps growing indefinately even when executing the same query and receiving the same result over and over. This will eventually lead to the worker process running out of memory (in our case, quite frequently).

Below is a code snippet that re-creates the behavior.

// The simplest possible query returning the same result every time will still
// increase the number of entries in the cache.

var cacheField = typeof(LambdaExpressionExtensions)
    .GetField("_cache", BindingFlags.NonPublic | BindingFlags.Static);

var cache = cacheField.GetValue(null) as ConcurrentDictionary<Expression, Delegate>;

cache.Clear();

Debug.Assert(cache.Count == 0);

var findClient = ServiceLocator.Current.GetInstance<IClient>();

// Make the simplest possible query to return one hit.

var firstHits = findClient.UnifiedSearch().Take(1).GetResult().Hits.ToList();

Debug.Assert(firstHits.Count == 1);

var firstHitID = firstHits[0].Id;

var firstHitCacheCount = cache.Count;

// The initial query should of course add entries to the cache. About 25 in my case.
Debug.Assert(firstHitCacheCount > 0);

// Make the same query in a loop.
for (var i = 0; i < 10; i++)
{
    var loopedHits = findClient.UnifiedSearch().Take(1).GetResult().Hits.ToList();

    Debug.Assert(loopedHits.Count == 1);

    var loopedHitID = loopedHits[0].Id;

    Debug.Assert(loopedHitID == firstHitID);

    var loopedHitCacheCount = cache.Count;

    // Given the same search query and the same result, the cache should not grow.
    // It grows with each iteration.
    Debug.Assert(loopedHitCacheCount <= firstHitCacheCount);
}

I want that visitors can see content only if the URL contains a specific key and value in url-parameters, for example `?clienttype=business`.

For that i have created following classes.

Setting class:

[EPiServerDataStore(AutomaticallyRemapStore = true)]
[PublicAPI("Used in module episerver vistorgroups")]
public class UrlParameterValidationSettings : CriterionModelBase, IValidateCriterionModel, ICriterionSettings
{
    public CriterionValidationResult Validate(VisitorGroup currentGroup)
    {
		if (string.IsNullOrWhiteSpace(Key))
		{
			return new CriterionValidationResult(false, $"{nameof(Key)} must not be empty");
		}
		if (string.IsNullOrWhiteSpace(Value))
		{
			return new CriterionValidationResult(false, $"{nameof(Value)} must not be empty");
		}
		return CriterionValidationResult.Valid;
	}
	public override ICriterionModel Copy()
	{
		return ShallowCopy();
	}
	public string Key { get; set; }
	public string Value { get; set; }
	public bool IsDeny { get; set; }
}

Criterion class:

[VisitorGroupCriterion(
	Category = "Custom Criterion",
	DisplayName = "URL-Parameter exists with a given value",
	Description = "Checks if a URL-Parameter exists with a given value")]
public class UrlParameterValidationCriterion : CriterionBase<UrlParameterValidationSettings>
{
	public override bool IsMatch(IPrincipal principal, HttpContextBase httpContext)
	{
		NameValueCollection requestParameters = httpContext.Request.QueryString;
		string value = requestParameters[Model.Key];
		bool matchingUrlParameter = value != null && StringComparer.InvariantCultureIgnoreCase.Equals(Model.Value, value);
		return Model.IsDeny ? !matchingUrlParameter : matchingUrlParameter;
	}
}

It works. But now i want that it will be validated only once and then keeps it value the whole browser-session. Currently it seems that it checks the url-parameter on every request. 

Even if i use the builtin "Visitor Group Membership" and add there a custom visitor group with the above criterion, it will always validate it on every request.

Is it a misunderstanding on my side how visitor groups work, or what is the correct way to implement this requirement? 

We are still on EPI 10 but will switch to 11 soon. Is this change in EPI11 what i am looking for or is it already possible in 10?

Hello

We use episerver CMS site 10.5 version. 

There are configured visitor groups criteria content (user IP criteria) - block with settings which are used in custom frontend widget (some booking widget).

So users from different Ip's see different settings. It works fine on our DEV env. But on PROD a load balancer (AWS hosting) is configured.

We have several versions of Web.config and transformations. On Web.Production.config is set specific parameter to use header for load balanced configurations:  

<appSettings>
<add key="episerver:ClientIPAddressHeader" value="X-Forwarded-For" xdt:Transform="InsertIfMissing" xdt:Locator="Match(key)"/>
</appSettings>

Also custom episerver Ip resolver was injected:

ClientIpAddressResolver : IClientIPAddressResolver

I added to the custom IP resolver traces and logging and see that method ResolveAddress returns correct IP address of user (not a load balancer IP) even on PROD site.

Also tried to define explicitly header with 'right' Ip address on Custom Ip resolver (to exclude version that web.config is not affects): 

private const string HeaderName = "X-Forwarded-For";

But visitor group content still not working. 

Another version is a caching on hosting side but AWS support says that there is no specific cache for PROD site. 

Hello,

I have a requirement to implement bookmarks feature in EpiServer. So when a user logs in, he could mark a content as favorite.

I will be storing userid and corresponding content id in a table. Assuming this will require me to create a new table in EPiServer database (not creating new database here since only one table)

Also when user logs in, I will be quering agains this DB table to fetch all content ids and load those content for user to view.

Can some one guide me on how to proceed on Database interaction in EpiServer and any best practices or reference links. I have seen link in this forum that talks about this feature already so if anyone can post some details that would be helpful.

Do we have a list of characters that are reserved or not expected to be part of string search?

Reason: I have some pages that start with "@" and If i have two pages with similar name, one that starts with @ and other that doesn't and if I search for page starting with @, I don't get this page as first result. Looks like this @ is completely ignored or escaped. Similar behaviour can be seen in EPiServer CMS when you search for a page.

I haven't got chance to validate the other special characters yet so the question, is it not advisable to have pages or blocks that are indexed to start with @ or $ or !.

Experiencing a bug when uploading a file for the first time on an EpiServer page.

Using the "+"-button as the image shows:

I get the following result with the "Content type "DocumentFile" is not allowed..."-message when hovering on "Mislyktes" (Norwegian for "Failed"):

The "DocumentFile" is defined as follows:

Getting this console message if helpful:

If I, however, use drag and drop to add the first file - it works. And when I then add a new file with the "+"-button after a file is uploaded with drag and drop, this will now also work.

So, the issue only occurs when uploading a file with the "+"-button the first time.

Is this a known issue? Or does anyone have an idea what causes this behavior?

Running EpiServer 11.12

There are atleast two search elements in the UI. The one Im refering to for this case is the one located in the top menu. (The magnifying glass)

The issue is that "nothing" happens when you click on the magnifying glass.

Some debugging steps I have been through:

• Created a new alloy app (MVC), and then tested that search. And it works.. 

This led me to start comparing things..

I opened the chrome devtools to see exactly what happens when you click the magnifying glass. And here we have some difference in the behavior between the Alloy App and my app. As soon as you click the magnifying glass, a request is done towards: ~/EPiServer/shell/Search/Index?searchArea=null

In the alloy case, that endpoint returns some markup. But for my app, the response is completly empty.

My App:

Did I install EPiServer.Search incorrectly? The thing is that the search component which is located just above the EPiServer content-tree 

Is working just fine 

We did upgrade from 10 => 11 a while back ago, could that be the issue?
I have diffed the Alloy Web.config with ours, not much is different there..
I have tested to run our app with the alloy database (same result)
I have tested to run the alloy with our database (the search still works)

I'm rather new to EPi, and I feel like I have exhausted the debugging steps that I can think of. If you have anything you want me to test, just shoot and I'll test asap.

Any help would be highly appreciated.

Thank you

How to enumerate blocks of contentarea in view to render? I have block1 and block2 in a contentarea and I want to render them separately unlike @Html.PropertyFor(x => x.CurrentPage.ContentArea).

Rather like below.
e.g.@Html.PropertyFor(block1 of contentarea)
@Html.PropertyFor(block2 of contentarea)

I tried to use Model.CurrentPage.ContentArea.Items.OfType<EPiServer.Core.BlockData>(). But how to use this in view?

The constructor for CacheEvictionPolicy that takes a TimeSpan expiration is obsolete. It is also not possible to set the expiration on the CacheEvictionPolicy after construction. Is there a non-obsolete way to achieve this?

Hi Forum,

I have a question about "IExtendedProperties". After saving a cart as a purchaseOrder, the values added to "IExtendedProperties" on payments disappear.

Is it a bug or intended behavior. Do I misunderstand something? :)

Screenshot cart order form

Screenshot purchaseOrder order form
https://screenpresso.com/=DZgdc

Code

var orderReference = _orderRepository.SaveAsPurchaseOrder(cart);
var purchaseOrder = _orderRepository.Load<IPurchaseOrder>(orderReference.OrderGroupId);

In DXC we can use Web.config transforms to modify our web.configs for different environments e.g. production.

My current project has json files which need transforms applied for various environments. Azure deploments also supports json config\transforms via JSON variable substitution as in link below.

https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/transforms-variable-substitution?view=azure-devops#json-variable-substitution

Is it posible to perform\configure JSON variable substitution for DXC deployments and if not what is the wrokaround?

Is there a way to get all the keys from an ISynchronizedObjectInstanceCache instance?

Hi!

We are currently using the Episerver DIBS payment provider found here: https://world.episerver.com/add-ons/dibs/

Our customer would now like to implement Swish payments, could that be done with the plugin above?
I know DIBS has the support but I'm not sure what version of DIBS you need etc, maybe someone has implementet Swish in Commerce via DIBS and can help?

Regards,
Kristoffer
