    Hi,

    I have a RAD combo box embedded in a grid that can have variable number of rows.  Each combo box is loaded with the same disconnected data table.  It works perfectly under light data entry, but when the combo boxes are searched repeatedly for values the response gets progressively slower.  Eventually there is a stack overflow error and numerous callback errors pop up.  I'm pretty sure the errors are happening in the Java code of the Combo Box.  I was able to capture some errors with firebug (an add on to firefox) the error listed is : __pendingCallbacks[i] is null.  The line of code referenced: "if(!__pendingCallbacks[i].async)" which is listed as line 163.

    This is NOT my code.  I've opened a ticket and received no response so far.  This is a very critical issue as my customers are quickly becoming dissatisfied with our data entry system.  Please help!

    Hello Gretchen Vanderburg,

    Thank you for the screenshots.

    The __pendingCallbacks array is actually in the ASP.NET AJAX framework code. On the other hand the 'error in the callback' originates in RadComboBox's code. The two may or not may not be related and we need to investigate this further.

    We have encountered the second problem a long time ago and did fix it. As I see the info of the forum post you have specified that you are using Telerik.Web.UI Q1 2009 last update, which is an old release, which most probably has the bug. Can you confirm that you are indeed using that version?

    Greetings,
