Hi all, I added the group feature to my datagrid, and it works fine however I noticed a strange error every time the mouse cursor is over the first row: Uncaught TypeError: Cannot read property 'addCls' of null
Any help please!

What version of Ext4 are you using?

Fixed in 4.2.2.1144 (EXTJS-10018)
