Add Row generates webpage error
posted

On adding an New Event after double clicking in add row field a WebPage error is generated "Error: 'null' is null or not an object." We ugraded Infragistics version from 11.1  to 11.2 thinking this might help but no avail. We updated Java to version 7 but no avail. Heres our code.

    Hi,

    Was this a problem with the WebDropDown and add row?  That was a bug that was found in the 11.2 RTM.  It would have been in a Service Release in 11.1 as well.  Its number was 98843.  It has subsequently been fixed.  Its fix will be available in the next SR.

    regards,

    David Young
