410604 - IAccessible2::Get_UniqueID does not return negative IDs, as specified by IAccessible2 IDL

Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect)

Description

[Marco Zehe (:MarcoZ)]

Following a discussion with Mick Curran in mozilla.dev.accessibility, it seems we are not returning negative unique IDs in the NSAccessibleWrap::Get_UniqueID method. See http://lxr.mozilla.org/seamonkey/source/accessible/src/msaa/nsAccessibleWrap.cpp#1316.

I am facing the same problem, that IAccessible2::Get_UniqueID is returning some garbage values, ie, consider I have two tabs, facebook.com and google.com, and facebook is selected first, 

if we check the  Get_UniqueID  it will be some -19000, after change the tab to google and when checking Get_UniqueID  will be -19054. when we again change the tab to facebook, it is supposed to give -19000 but result from Get_UniqueID   will be again some random number.

Thanks in advance.
