with the help of the gread tutorials 'Master Of Columns I & II' I was able to write a small application using TreeByNestingTableColumn. My value node in the context uses a supplyFunction.
I now have the problem, that I would like to recreate the treee by buttonclick.
I tried to empty the context node (ctxnode.bind(Collections.EMPTY_LIST)) and to call my supplyfunction directly. But this didn't work.
Can anyone help tell me what I have to do to be able to manually create/reload the tree?
Thanks a lot,
