Hi,

I have many error with the constructor of 'Telerik.Web.UI.ExternalScriptHelper'.
I can not reproduce this error in local, and we only have it from time to time in production
So I need your help to understand what could cause that.

In my call stack I have this.
This call stack was created with DebugDiag v2.0

Hi Christophe,

Can you confirm the version you are using? I am asking this because a similar issue is fixed in the summer and you should not experience it with the latest release (Q3 2014 at present). Thus, I would advise upgrading to that version.

Another common reason for a similar problem is when serving external files (not embedded in assembly) with the RadScriptManager, the folder which contains these files should be specified in the web config file as explained here: http://www.telerik.com/help/aspnet-ajax/scriptmanager-combine-scripts.html and in case this registration is missing, you can get such errors.

Hi Marin,

Thank for your response. We use release Q1 2014.
We don't reference script in web.config because we need dynamic script.
So we use either C# code (ex RadScriptManager.RegisterClientScriptInclude) or with a RadCodeBlock.
Do you think this can create a bug ?
Update to the Q3 release is heavy work for us. We need to verified all screen are always compatible, and may be adapt the code. So, we need to be sure that this bug is fixed in this release before.

Hello,

Without being able to observe the problem I cannot be completely certain what it is and what causes it. Thus, I cannot confirm whether creating scripts dynamically will cause the same problem I was referring to.

What I can suggest, is giving upgrading a very quick test - simply change the assemblies and test a page that you know causes this problem. If it does not manifest again, then it is a bug that has been fixed in a later version and upgrading is, most likely, the single option. 

It is also possible that this is a false positive - we may be throwing an unnecessary exception, which is then catched. Nevertheless, the DebugDiag tool still catches it and reports it to you. We have had one report about such behavior a few months ago.
