Grid reconfigure method not clearing old column headers in beta4
In beta4, I noticed reconfigure method in Grid is not clearing old column headers. Table shows two column headers after reconfigure method is called. But in beta2 it was working fine.
I'm able to reproduce this error in simple example. Attached sample code in this. When you click on "Include Middle Name" button, Grid creates multiple header.
Note: you need to have two ids(toolButton, gridTester) to include button and grid in the html.
Thanks for the report and for providing a complete test class. However, this issue has already been raised in http://www.sencha.com/forum/showthre...)-you-get-dups, and it has been fixed in SVN. Please follow that thread for any further discussion of this bug.
