Hi there,

I've been using NHibernate Burrow and ASP .Net Telerik Controls in an application. Everything worked well until I recently upgraded from 2009 Q1 to 2009 Q3. It seems that the way DialogHandler now constructs the dialog page causes issues with NHibernate burrow - I'm getting NullRefException on PreRender. I guess Burrow tries to find the page form to insert the Burrow place holder. If I take the burrow module out all works well.

Anybody came accross similar problem or does anyone know what change or suggest a work-around ?

Many  thanks,
Mira

Hi Mira,

Please, try the fourth suggestion in this KB article: Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file, e.g.

  1. open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd
  2. set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd"

This should do the trick.

Kind regards,

Hi Rumen,

Many thanks for your reply. I'm afraid that I already tried all the options on the KB article with no luck before raising the ticket (Including changing the handler to axd and setting the DialogHandlerUrl).

I created a small example and uploaded it online (I could not attach it due to the file size restriction). It is 14.3MB with the DLLs.

The changes in dialog rendering from Q1 to Q3 clearly prevent us from upgrading unless we can find a solution.

Best Regards,
Mira

Hi Mira,

Thank you for the provided sample project.

I was able to reproduce the problem and logged it for research and fixing in our bug tracking system. You will be able to check its status in the PITS system.

Hi Rumen,

Many thanks for your reply. I'm unable to find the issue in PITS. Tried searching or looking looking under ASP.NET AJAX controls with no luck. How did you name it or how can I find it ?

Cheers,
Mira

Hi Mira,

You can find the issue in the following page: http://www.telerik.com/support/pits.aspx#/public/aspnet-ajax/not-scheduled. You should be logged in the site.
For your convenience I have attached a video demonstrating the item.
