    Default [4.2] Reload a TreePanel with static JSON data will only expand first level children

    [4.2] Reload a TreePanel with static JSON data will only expand first level children


    Hi,

    Since I upgraded to ExtJS 4.2, I have this problem. I initialize my TreePanel with a static JSON file. All the children are expanded. Then, later during application execution, I load another JSON file. This time, only the first level children are expanded, although they show the expanded folder icon.

    For more details and screenshots, see http://www.sencha.com/forum/showthread.php?259147-TreePanel-loading-bug-with-JSON-data
