I chnaged the code to
dataProvider="{ MyModel.getInstance().activities }"
it works, doesnt reorder anything however it doesnt hide the tree
nodes I want hidden..
I'm considering dumping the Flex idea and just cutting out those
activities in the DB with a simple 'isactive = 1'
But I would love to know why Flex is reordering the nodes and also if
I open the tree node and drag one of the childs the bottom node
vanishes.. it's there but it's not.. nothing displays..
