I have an app which builds song playlists. There are left and right pane
containers with the left containing a qx.ui.tree.Tree() of all songs (titles
within albums within artists) and the right containing a qx.ui.form.List().
Creating a playlist involves dragging and dropping song titles from the tree
onto the list. Starting with 4.0 I am having the following problem. In the
"droprequest" event listener on the tree I check to see if the CurrentAction
is move, and if so I remove the selected TreeFile from its parent TreeFolder
with code similar to:
function(e) {
var sel = this.__musicTree.getSelection()[0];
...
if ("move" === e.getCurrentAction()) {
var parent = sel.getParent();
parent.remove(sel);
}
}
In 3.5, parent referenced the qx.ui.tree.TreeFolder(), but in 4.0 parent is
null.
Has something changed, was I doing something that I shouldn't have, is this
a bug?
