ListGrid Expand error

[gvangass]

When a ListGrid is in edit mode, and you click on the expand component, it gives you an error. See attachment.

I'm using smartGWT 2.2 in FireFox 3.6.8 on Ubuntu 9.10

    TestDS dataSource = TestDS.getInstance();

    ListGrid listGrid = new ListGrid();
    listGrid.setWidth(600);
    listGrid.setHeight(500);
    listGrid.setCanExpandRecords(true);
    listGrid.setExpansionMode(ExpansionMode.DETAILS);
    listGrid.setAutoFetchData(true);
    listGrid.setDataSource(dataSource);
    listGrid.setCanEdit(true);
    listGrid.setListEndEditAction(RowEndEditAction.NEXT);

    listGrid.draw();

Can someone confirm that this is a problem with smartGWT, or a problem on my side ?

Are you seeing this in the latest nightly build as well? See this FAQ entry on what information to provide.
