Memory leak when i set new root node into TreeStore
REQUIRED INFORMATION
Ext version tested: Browser versions tested against: - FF 16.0.2
- IE8
- Opera 12.02
Description:
We have memory leak, when dinamically(timeout 1 sec):
- set new root with his childs in TreeStore, which data interpret by treepanel; OR
- remove all child nodes of root node and append new nodes into it.
Steps to reproduce the problem: - See ext js code and json data below;
- Open the application in IE8, click on checkbox(refresh);
- Open task manager;
- See on memory state of IE process.
The result that was expected: The result that occurs instead: Test Case:
Code:

{
var childs = Ext.clone(store.getRootNode().childNodes);
treepanel.setRootNode({

expanded: true,
children: childs
});
}
}
}});
tempStore.load();
var runReloadTreePanel = Ext.create("Ext.util.TaskRunner");
var taskTree = {
