XForms not working in blocks

Hello,

I'm having some problem with getting XForms to work in a block. It's webforms and not MVC.

XForms works when I put them on a normal page, but when I use them on blocks I get a null exception. See below.

Exception Details: System.ArgumentNullException: Value cannot be null.
Parameter name: virtualPath

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

I tried to compare with the Alloy templates, but find no difference that should break it like this.

I also tried to debug, but it doesn't stop at any break points that could give any information.

Anyone know what the problem could be? Thankful for any help.

I found the solution to this problem, but not why the problem occured. My guess would be that episerver cached the renderer and try to access an older version of it that did not exist.

Solution was that the renderer for the block seemed to be corrupt in some way. What I did was to delete the webcontrol that was the renderer, enter edit mode and get the error "no renderer was found for block and then create it again.

So the problem the problem seems not to have been with the xforms module
