Purge build output directory

[DEGARDIN David (CAMPUS)]

Hello,

I'm using continuum-1.2.2 and there is something I do not understand
well. I've added a purge configuration like this for the buildOutput:
        - deleteAll = false
        - days older = 30
        - retention count = 30

When I click on the "purge" button, nothing happens (no redirection to
another screen, no purge, nothing in logs...). I do have build results
older than 30 days, they're still here...

Am I missing something ?

Thanks for help

David
