Status: UNCONFIRMED

(Core :: DOM: Copy & Paste and Drag & Drop, defect, P5)

Description

[teramako]

Attachment: dd_test.xpi

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:12.0a1) Gecko/20120125 Firefox/12.0a1
Build ID: 20120125064912

Steps to reproduce:

dataTransfer.dropEffect on dragend event (which fired after dropped into a custom tree view) always "none" even if dropEffect is set on dragstart
so we cannot awake to the drop action was success or not.

----
I created a test case (attachment xpi).
install the xpi file and goto chrome://DDTreeTest/content/dd_test.xul



Expected results:

nsITreeView.drop is called, the dataTrasnfer.dropEffect should inherit
