Rebinding com.allen_sauer.gwt.dnd.client.util.DragClientBundle Warning

[zbeedatm]

Hi,
I'm trying to use a gwt connected graph, I tried so far 2 gwt projects:

1. gwt-connector (https://code.google.com/archive/p/gwt-connectors/)
2. gwt-links (https://code.google.com/archive/p/gwt-links/wikis/GettingStarted.wiki)

both requires gwt-dnd (I have gwt-dnd-3.3.4), but when trying to load the app am getting this Warning and the connected graph is not shown at all or doesn't function as expected:
