Hello everyone,
I have created a recycle bin component for Java and it functional. As of now I have all recycle bin cabinent so all users can read, write and delete objects. The problem I am having is if a user deletes an object it gets sent to the recycle bin and only that user can see it in the recycle bin. When I log out and log in as an admin the object is not visible in the recycle bin. I have included my recyclebinclass.java and the destroy method from my TBO which calls my softDelete in my SBO
