[4.1.1] Ext.grid.feature.Grouping - startCollapsed not working with remote data

[Steferson Patake]

i came with a better approach:

changing the listener from the form panel to the store, like this:

var storeOpcoesAcesso = Ext.create('Ext.data.JsonStore', {
...
groupField: 'descricao',
listeners: {
  load: function(este, opts) {
    groupingFeature.collapseAll();
  }
},
...
});

now its working fine

Thank you for sharing your findings!

We all are curious when it will be fixed in ExtJS

These "fixes" do not seem very efficient at all. I mean listening and collapsing after the store has loaded the data seems incredibly inefficient especially in grouping grids with 20-30 groups.

The only real fix should be that they are initially collapsed when rendered after adding them to the store.

I really wonder why this was not fixed since it is an old issue.

In 4.1.1 I used this to fix this problem

grid.getView().on({                 'beforerefresh': function(view,eOpts) { 
                    return false; 
                },             
                single: true 
            });

And similiar to then expand single groups which had its expansion state saved in a session cookie.

Doesn't work in 4.2 anymore however. Does nothing.

Maybe someone should report this bug in the 4.2 forum.
