Force refresh of a CellTree?

[membersound]

Hi,

I have a CellTree where onSelection I change a specific element.
BUT if I reselect an element that was selected before, the changed value is NOT updated in the view. Only if I fold and unfold the tree I see the changed value visually.

Question: how can I fore the tree to refresh itself without having to fold/unfold it?

ListDataProvider or AsyncDataProvider?

ListDataProvider.

Have you called yourDataProvider.refresh() after the value change?

Also the second answer from here could help: http://stackoverflow.com/questions/7239960/programatically-refresh-a-gwt-celltree

Ok I now created a HashMap<MyItem, ListDataProvider<MyItem>> for holding a reference to all subItems, and the key is the parent item.

And for each refresh I first detect the subItem, get its parent, retrieve the subDataProvider from the HashMap using the parent, and then forcing the .refresh() on that particular subdata.

I feel that's lots of boilerplate, but could not find another way...
