    Hi,

    As the post title says m kinda confused about this, i have a CascadingDropDown ASP control which is filled by a WebService but when i try to "Ajax-enable-it" with RadAjax i got a strange bug on a telerik resource which seems to be a RadAjaxManager caller and the only thing i can see in the error console from Firefox is "b is null" and obviously any postback raises the same error.
    Taking out the control makes everything work perfect but as you may understand isn't a solution, also tried to mitigrate that control to RadComboBox but samething happen...
    M gonna try to make some some example code tomorrow but maybe someone here already experience something similar and know the answer...

    Best Regards

    Sorry,

    The error was related to a know bug of the cascadingdropdown extender from the ajax control toolkit.
