View Full Version : Potential EXT 4.0.2a bug with desktop example

22 Jul 2011, 11:21 AM
Steps to recreate from Desktop Example:

add an 'Ext.selection.CheckboxModel' to the grid in the Grid Window
Close the window
If you try to open the window again, you get an error stated below.

Error: "header is null" from javascript command 'delete header.width;'

Using FF5 with EXTJS 4.0.2a on a Windows 7 machine.

So far i'v seen a lot of posts about not working components in deskop example after u try to reopen a window in it. Seems like deskope example is simply broken or a funcion responsible for closking modules is not working as it suppose to.

table headers,
tree grid,
those are only three components that are not working properly with it.
