I am making a application in qooxdoo to create a tree. Then I move some nodes
with events:
Button.addEventListener("execute",function()
{TREE.getSelectedElement().moveSelfAfter(TREE.getSelectedElement());});
When I am in the end of the widgets list, I get this error debug:
009092 ERROR: qx.ui.form.Button[150]: Could not dispatch event of type
"execute": TypeError - vChildren[i] has no properties

To correct this I chance the implementation of addAfter in class
qx.ui.core.Parent:
/*!
Add a widget after another already inserted child
*/
qx.Proto.addAfter = function(vChild, vAfter)
{
var vChildren = this.getChildren();
var vTargetIndex = vChildren.indexOf(vAfter);
if (vTargetIndex == -1) {
throw new Error("Child to add after: " + vAfter + " is not inside this
parent.");
}
var vSourceIndex = vChildren.indexOf(vChild);
if (vSourceIndex != -1 && vSourceIndex < vTargetIndex) {
vTargetIndex--;
}
return this.addAt(vChild, Math.min(vChildren.length-1, vTargetIndex+1));
/* return this.addAt(vChild, Math.min(vChildren.length, vTargetIndex+1));
OLD CODE*/
}
