    i came with a better approach:

    changing the listener from the form panel to the store, like this:
    Code:
    var storeOpcoesAcesso = Ext.create('Ext.data.JsonStore', {
    ...
    groupField: 'descricao',
    listeners: {
      load: function(este, opts) {
        groupingFeature.collapseAll();
      }
    },
    ...
    });
    now its working fine

    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

    Code:
    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.

    Default Solution for 3.4

    Solution for 3.4


    This worked for me:

    Code:
    new Ext.data.GroupingStore({
    ...
     ,listeners: {
               load: function(este, opts) {
                   groupingView.startCollapsed=true;
               }
     }
    Thanks for the code

    Sencha lazy bastards

    Code:
    Ext.override(Ext.grid.feature.GroupStore, {
    	processStore: function(store) {
            var me = this,
                groups = store.getGroups(),
                groupCount = groups.length,
                i,
                group,
                groupPlaceholder,
                data = me.data,
                oldGroupCache = me.groupingFeature.groupCache,
                groupCache = me.groupingFeature.clearGroupCache(),
                collapseAll = me.groupingFeature.startCollapsed;
    
    
            if (data) {
                data.clear();
            } else {
                data = me.data = new Ext.util.MixedCollection(false, Ext.data.Store.recordIdFn);
            }
    
    
            if (store.getCount()) {
    
    
                // Upon first process of a loaded store, clear the "always" collapse" flag
                // DISABLED ONLY THIS =>>> me.groupingFeature.startCollapsed = false;
    
    
                for (i = 0; i < groupCount; i++) {
    
    
                    // group contains eg
                    // { children: [childRec0, childRec1...], name: <group field value for group> }
                    group = groups[i];
    
    
                    // Cache group information by group name
                    groupCache[group.name] = group;
                    group.isCollapsed = collapseAll || (oldGroupCache[group.name] && oldGroupCache[group.name].isCollapsed);
    
    
                    // If group is collapsed, then represent it by one dummy row which is never visible, but which acts
                    // as a start and end group trigger.
                    if (group.isCollapsed) {
                        group.placeholder = groupPlaceholder = new store.model(null, 'group-' + group.name + '-placeholder');
                        groupPlaceholder.set(me.getGroupField(), group.name);
                        groupPlaceholder.rows = groupPlaceholder.children = group.children;
                        groupPlaceholder.isCollapsedPlaceholder = true;
                        data.add(groupPlaceholder);
                    }
    
    
                    // Expanded group - add the group's child records.
                    else {
                        data.insert(me.data.length, group.children);
                    }
                }
            }
        }
    });
