Requirement validation between Rational artifacts and HP ALM test folders can fail if the HP ALM test folder is locked.
Steps to reproduce:
From the HP ALM adapter web interface:
1. Open a Testplan folder.
2. Click on Select in the Validated Requirement Collections pane.
3. Select any collection.
You see an error message similar to the following:
CRIHP0005E: Creating my-requirements-collection links for Test Folder 123 in project my-test-project failed. Failed to lock test-folder with id 123, the entity is locked by: <username>
Another HP ALM user has locked the test folder. This occurs when the cursor focus is placed in a text area field on the HP ALM client.
HP Adapter 1.1.0 and HPALM 11.5
Resolving the problem
You can re-try the operation in a few minutes after the lock has expired.
