Combogrid onSelect not fire when using setValue or $('#fm').form('load', row)

[patana]

I'm currently using version 1.33
The problem is i want to load data into a form when user want to edit.
But my combogrid seem not fire onSelect event for the first time, but it work on second time with the same row on datagrid.
If i change to edit another row on datagrid, then i need to edit twice to make it fire the onSelect event on combogrid.
