[CLOSED] [#165] Exceptions in DirectMethods

Hi,

It works if remove "Shared" from the DirectMethod definition.

Does VB "Shared" just mean C# "static", right?

We will investigate a possibility to support "Shared".

By the way, here is an example of handling Exceptions with DirectMethods.

Thank you Daniil.

Once I removed "Shared" the exception got to my error handler. However it is still wrapped up into a TargetInvocationException. I can work around it but if you know what causes TargetInvocationException and how to get rid of it please let me know. See exception info below with RethrowException On and Off.
Error with

<DirectMethod(RethrowException:=False)>

 System.Exception: my test exception at ASP.test_aspx.TestError(String s) in C:\TFS\ScrumVMS\VMS - 6.0.5\WWWROOT\test.aspx:line 15

Error with

Well, "Shared" is supported the same way as C# "static" is.

The problem is the fact that static (Shared) DirectMethods don't use global ResourceManager and Web.config RethrowAjaxExceptions settings. So, for static (Shared) DirectMethods please use the RethrowException setting.

We will try to change it in Ext.NET v2. Thanks for pointing it out. But in Ext.NET v1 the things will be left as they are now.

This exception is thrown by the Invoke method.

We take an inner Exception for non static (non Shared) DirectMethods. So, you can take an inner exception for static (Shared) exception manually.

We created an Issue for v2.

It has been implemented for Ext.NET v2.
