    refs: omitted…
    init: omitted…
    doAfterActivate: function() {
        var me = this;
        me.getTaskStore().load();
        me.getProjectStore().load();

    doSelectProject: function(combo, records) {
        var me = this;
        var rec = records[0];
        if (!Ext.isEmpty(rec)) {

                property: 'idProject',
                value: rec.get('idProject'),
                exactMatch: true
            });
