ListGrid fixed column giving javascript error on mouseover

[Halabe]

Hi,

I have a listGrid with a field that is frozen and does not have a headerContextMenu.

The field is defined as below.

       setCanEdit(false);
        setWidth(20);
        setCanFilter(false);
        setCanSort(false);
        setCanGroupBy(false);
        setCanHide(false);
        setFrozen(true);
        setShowHover(true);

When I put the mouse over the header of the field, I get the attached error in development mode and a javascript error in production mode (length is null or not an object).

Note that I am using:
SmartGWT 1.3 revision 800
Internet Explorer 7 (Error does not appear in FireFox)
GWT 1.6.4

Thanks for any help!

It looks like you've overridden the getHeaderContextMenuItems and are returning null. Try returning an empty list/array instead. We've changed the framework to handle either case in the future.
