Bug in Ext.data.BufferedStore when using a grouped stateful table
Ext version tested:
Browser versions tested against:
- Chrome 40, but: doesn't matter
DOCTYPE tested against:
Description:
When using a grouped stateful grid on a Ext.data.BufferedStore the method applyState() is called as expected. The method itself calls setGrouper() with is a setter on the grouper config property. This calls applyGrouper() in Ext.data.AbstractStore which in turn tries to call this.getData().getGrouper(). This does not work on buffered stores however.
Steps to reproduce the problem:
Just run the following fiddle twice. On the first run the grid renders as expected (no state in the cookie), but it fails on the second run when it tries to apply the grouper state as described above.
The result that was expected:
The result that occurs instead:
- grid is not displayed

Anything new on this one?
Is there an ETA? 5.1.1?
Cheers

Hey guys,
anything new on that one? There's not much going on in terms of bug fixing for 5.1.2. Any chance this issue gets fixed before shifting focus fully on Ext 6?
Sorry for being dogged, but we're on 5.1 and we need these fixes...
Cheers

Looks like this bug is still in 6.2.1.29. Any news on that? Workarounds?

As a workaround i have overriden the getState function on my store:
Code:
getState: function () {
Ext.log(this.self.getName() + ": getState");
var result = this.callParent();
delete result.grouper;
return result;
}
