Hi meandi,
I couldn't reproduce the issue you described using the code snippet you
provided (along with the setDefault() method implementation below.
private void setDefaults(){
// Building the tree ...
TreeItem root = new TreeItem("root");
root.addItem("item0");
root.addItem("item1");
root.addItem("item2");
TreeItem moreItems = new TreeItem("moreitems");
moreItems.addItem("moreitems1");
moreItems.addItem("moreitems2");
moreItems.addItem("moreitems3");
root.addItem(moreItems);
tree.addItem(root);
}
Could you provide more details about which browser you were using when you
encountered this issue? As well as which type of widgets you were adding to
the Tree when the double-fire error occurred?
Cheers,
-Sumit Chandel
