[CLOSED] Grouped Buffered GridPanel won't Collapse

[stratadev]

It appears that a GridPanel that is using the buffer plugin and grouping feature won't collapse. After digging deeper it looks like the onGroupClick method is called twice when the group header is clicked and the group is already expanded. This results in a quick collapse expand resulting in no visual change. After calling collapse manually the default expand seems to work fine (only one call to onGroupClick).

For the time being I'm getting this to work by overriding onGroupClick:

Ext.override(Ext.grid.feature.Grouping, {

    onGroupClick: function (view, group, idx, foo, e) {
    }
});

...and using GroupClick listener like this:

    groupClick: function (view, node, group) {
        if (item.features[0].isExpanded(group) == true) {
            item.features[0].collapse(group);
        }
        else {
            item.features[0].expand(group);
        }
    }

This to me feels like a bug any suggestions?
Also it seems like StartCollapsed="true" does not do anything at the moment...

Thanks,
Ryan

Hello everybody,

I can't reproduce the problem with the latest sources from SVN.

I think it has been fixed yesterday.
