    Howdy at Telerik

    I have a web project that generates a strange error when run in ' compilationDebug="false" '

    There is no error when ' compilationDebug="true" '.

    The page that generates the error consists of Five 'Ajax Collapsiable Panels holding five RadGrids' when i make a selection in a treeview outside the panels and press a button the panels are either shown and radgrid(s) rebinded or the panels are collapsed.

    I have a RadScriptManager together with a RadAjaxManager on the Masterpage and a RadAjaxManagerProxy on the inherited Page.

    When compilationDebug="false" i get the error shown on the image i have attached to this thread.

    Hope you can help me with this rather strange error, or maybe explain why this only happens when debugging is disabled. 

    Sincerly Jan.

    Hello Jan Pfeffer,

    To my regret this information is not enough for us to determine what could cause the problem.

    Can you please try to create a simple test project and see if you face the same error there?

    We have a similar problem in RadTabStrip which occurs when using  the debug version of the MS Ajax library (which is the opposite of your case)

    Hey Veskoni

    My problem was due early initialization of a singleton object which held a session variable.
    Fixed by setting the variable after the singleton object was created.

    Thx for your time though.

    Sincerly Jan
