You will have to get the object you want to be open and add it to the
I can get the object that's not the problem, the problem is to which event I should be listen to to collapse the node?
Try using the expandItem method. If you've just set the dataProvider, you
could try calling validateNow() before calling expandItem
Maybe it's the luck of my English maybe not but the problem is not with the dataprovider because it's added beforehand the request to the remote happens.
-> after data is back from the remoteobject this will be added to the tree
-> unfortunately even the data is available and rendered ( i can see it ) no datachanged event fired on the tree after previous point ( I don't know why) even I use the removeAll / addAll functions on the ArrayCollection (dataprovider) which should fire Collection_Change(multiple times) event and then trees datachanged event should be fired according to the docs
-> I'm looking for an event where I can do the expand on one of the items in the tree after it's rendered and available?
Maybe the tree works differently for the underlaying dataproviders change event and it's missing in the docs so I'm still looking for a solution to that?
