I have an AdvancedDataGrid using a HierarchicalData object (
I attached the code to this message). If I expand a node so that I
can see it's children, then click "new employee" (which adds an
employee to the currently selected EmployeeGroup) the employee
doesn't show up in the display.
If however, I select an EmployeeGroup (before ever expanding
it) and I click "New Employee", then expand that EmployeeGroup the
new employee is displayed.
