Build Identifier: 201110110900

DnD a DataGrid into a handler, run the handler in preview or deploy, then click the Column Header to sort the column, there will fire an error:
[CRRUI1083E] An error occurred while the click browser event was being handled.
[CRRUI2005E] A null reference cannot be used.
[CRRUI2094E] Here are the EGL function calls leading to this error:


Reproducible: Always
Comment 1 Huang Ji Yong CLA 2011-10-12 02:39:06 EDT 
This is a JSGen problem.
The generation for DataGrid.egl clickGrid function line 249 is wrong
The EGL code is
while(widget.class != "EglRuiDataGrid" &&(widget.getAttribute("column") as int) == 0)
            widget = widget.parent;
        end

The generated js is
var eze_compound_1 = false;
			eze_compound_1 = ((egl.checkNull(widget).getClass()) != "EglRuiDataGrid");
			if (eze_compound_1) {
				eze_compound_1 = ((egl.eglx.lang.EInt32.ezeCast(widget.getAttribute("column"),false) == 0));
			}
			while (eze_compound_1) {
				widget = egl.checkNull(widget).getParent();
			}

Here while (eze_compound_1) will always true because it only evaluated once. But actually, when widget changes, the while expression have to be evaluated again.

In preview mode. If you click the data items in the data grid. the column will be abnormal.
