I use a grouping feature on my grid. When I click on a group I simply iterate through my store and change some properties using set. But the attribute doesn't get set no matter what.. Here is my code:
onGroupClick(node, view, group){
var store = Ext.getStore('someStore');
store.data.each(function(item, index, totalItems ) {
if (item.data.id == somecondition ){
item.set('displayName', 'someName'); //DOES NOT WORK
}
});
}
EDIT: the field being set uses a converter.
