I Use ExtJS 4.1 and use fieldset
, collapsible: true,
but initialy it must be collpsed, so i set collapsed: true
, but the fieldset
is not rendered, and it trows error in consol` Cannot call method 'getFrameInfo' of undefined,
can please someone tell me the reason of issue, and the solution?
I had exactly the same problem. The problem has something to do with the layout of your parent. Just set the layout parameter
of your parent and it will work just fine.
Here is a working example.
