TC11.2.1: Issue while Revising


After upgrading from TC9.2.1to TC11.2.1,  I found a strange issue while revising items.


When I try to revise a Item from Rev0 to Rev1 I get error messages like


1. "wso cannot be based on more than one wso"

2. "the instance is not locked"


I also found that, this issue exist only for those items whose "Rev0.iman_based_on" relation property is non empty . If we clear the property on the Revision object, it completes smoothly.


Anybody who faced or has similiar experience? Attached error snapshot
