Custom WEB ADI for Item Category Assignment

Question

Hello,
We created following custom WEB ADI .
1.) Item Update  ( No Security )
2.) Item category assignment ( WITH Security of Organization Access )
Created custom responsibility XX_INVENTORY with custom Menu (subset of INV_NAVIGATE)
Added responsibility/organizationsfor XX_INVENTORY using organization access form.
NOW
POINT 1: Both ADI works as expected when added as function to Standard Inventory responsibility with menu INV_NAVIGATE.
POINT 2: Item Update ( with No Security) Works fine from custom responsibility
POINT 3: Item category assignment (with organization security) fails with "invalid integration key" error from custom responsibility. But if the user has "System Administrator" responsibility to his account it works fine, which makes me think that it has to do something with custom responsibility.
Applicatio: R12.1.3
Excel 2010
BNE Allow No Security Rule to Yes at user level
Any help is appreciated.
Thanks

Hussein,
Still the same even after bouncing application. But if application bouncing was issue then none of the custom ADI should have worked from custom application. But ONLY ONE of the two is not working. Item update ADI is working just fine but Item Category assignment is not.
Any more clues??
I tried by adding Create Document, adding Desktop Integration menu to custom responsibility menu, nothing works. As soon as I add "System Administrator" responsibility to User  OR add the custom ADI function to standard inventory responsibility with INV_NAVIGATE menu, it works.
Please let me know if anybody has any clue on this issue.
Thanks
