TreePanel with "rootVisible: false" not showing anything in Ext 4.2
Ext version tested:
- Ext 4.2.0
- Chrome Version 25.0.1364.172 m
I can't get the treepanel working in the new Ext 4.2.0 version. Specifically when I don't want the root to be visible. I provide 2 test cases.
Steps to reproduce the problem:
- define, create and load an 'Ext.data.TreeStore',
- create a treepanel with the rootVisible set to false.
- list of folders (optionally leafs, but not in my test data)
- no list empty, 0 height panel showing.
working Ext 4.1.1 example:

Additional CSS used:
- only default ext-all-debug.css
- Windows 7 - 64Bit

It looks like it's the leaf field that you have in your model.Mitchell Simoens @LikelyMitch

Thanks for putting me on the right track!
The issue was indeed with the converter on the leaf field. Behind the scenes Ext creates a root node if no root node is present. In previous versions the newly created root node wasn't passed through the converter in Ext 4.2 it is past through the converter. In my case I checked if type is 'folder'. But the root field has no type resulting in being a leaf. Resulting in not showing anything. (because the root was hidden)
