I have a fairly complicated page layout -- there are tables inside of tables that contain multiple controls, one of which is a WARP panel in one of the rows.  I have a WebGrid in the WARP panel and one of the columns in the grid contains a WebCombo.  The WebCombo is populated correctly when the page first loads.  When you change a value in the WebCombo and save the changes things go well, but when it tries to load the values back into the WebCombo it causes problems.  In IE I get the "Object reference not set to an instance of an object" error but in Firefox it just populates with the wrong value and doesn't throw an error.

This didn't happen before we added the WARP panel to the code.  Are there known issues with WebCombos and WARP panels?  Does anyone know of any work arounds?

Any assistance would be greatly appreciated!
