Has this item on the backlog been implemented?
I ask this, because I just had the opposite behaviour from what Gonçalo described. We have a global theme with an OnSessionStart that loads some generic data in the session. When I login to the application that uses this theme, the OnSessionStart of the Theme runs correctly and the application works.
The problem is that when I logout and login again, the OnSessionStart of the Theme is skipped and I get an error loading the first page that uses the generic session variable.
I'm using platform 9.1.603.0
The backlog item was for the documentation and not for the product. If you find the behavior is not aligned with what is described in the help please submit a ticket to support.
