Grouping with startCollapsed doesn't allow to expand a group using its expand method

[Daniil]

Hello ExtJS team,

Apologize for the lack of the details, but I hope the problem is obvious.

Please let me know if you need any more details.

Ext version tested:

• Ext 4.1.0

Description:

• The expand method doesn't expand a group if the Grouping feature is configured with

  startCollapsed : true

  because it checks

  if (me.collapsedState[groupName])

  which is initially undefined for all groups undepending on startCollapsed.

I've worked around the problem calling the collapseAll initially which set up

me.collapsedState[groupName]

to true for all groups.

I actually ran into this last week when creating expand all button but forgot about it.

I also ran into this right now.

After a little testing i did a Ext.override that fixes the missing/wrong initialized collapsedState when startCollapsed is set.

Here is my code and it works fine so far in both cases manually expand by click and expand by calling expand.

Ext.override(Ext.grid.feature.Grouping, {	onGroupClick: function(view, rowElement, groupName, e) {
		var me = this;
		if (me.startCollapsed && !Ext.isBoolean(me.collapsedState[groupName])) me.collapsedState[groupName] = true;
		me.callParent(arguments);
	},
	expand: function(groupName) {
		var me = this;
		if (me.startCollapsed && !Ext.isBoolean(me.collapsedState[groupName])) me.collapsedState[groupName] = true;
		me.callParent(arguments);
	}
});

Hi Mitchell,

Please clarify is this still not fixed? I just can't see the bug id to check it quickly in the release notes.

Maybe are you able to post a link to the thread which this one duplicates?
