Hi there,

I'm trying to add a group tab dynamically, and I get the following error at line 43287 of ext-all-debug.js... It looks like the initTab method for a standard Tab is getting called rather than the one on the derived 'class' GroupTab:-

Uncaught TypeError: Cannot call method 'insertBefore' of undefined

Any help greatly appreciated!


BTW This is with ext 3.1.1...
