[CLOSED] Ext.net 2 Beta Release: Error when rebuilding grid
Hi!
After I update source codes of ext.net from subversion and recompile, I'm getting this error when I rebuild my gridPanel.
Runtime Error in Microsoft JScript: Object does not support property or method 'onChange'
Attachment 4102
I made a little example... please, click in 'Refresh' button to trigger error.
