Hi wgw,
that's crazy, the problem is the alert message box, remove it and you
will see that the error is gone.
It seems to me that the alert execution change something so that the
getData call think he is not in a drop event.
Cheers,
Chris

I'm learning qx 1.1 by combining the drag-drop list demo with the tree
demo so that I will have a drag-drop tree demo. I want to be able to
construct one tree (as is in the tree demo) and then drag items from
that tree to another tree (as in the list demo).
Everything seems to work fine until the drop point, where I get an error:
Error: This method must not be used outside the drop event listener!
Source File:
file:///home/bill/Soft/hack/Python/qooxdoo-1.0.1-sdk/framework/source/class/qx/event/handler/DragDrop.js
Line: 204
The problem is the the getData method. Yet I don't see how that error
message applies in my case, because the only place I use getData is in
an event listener. Here is my listener for the target tree:
tree2.addListener("drop", function(e) {
alert(e.getRelatedTarget());
var items = e.getData("qx/tree-items"); //this is a problem???
for (var i=0, l=items.length; i<l; i++) {
this.add(items[i]);
};
});
I have no idea why I am getting an error here, though I suspect I am
using misusing "this" or there is an event bubble effect that I have
not been able to follow.
Any pointers on how to solve this? The full code is attached
(Application.js <http://n2.nabble.com/file/n5020171/Application.js>).
Thanks!
