When creating an ad hoc report, it is possible in the Data Chooser wizard to save the configuration of the fields, pre-filters and display as a topic in the 4th step.
When opening the Data Chooser again, it should be possible to see the topic in first page - at least if using the same user who created the topic before. Unfortunately, I cannot see any topic.
Checking with superuser, I can see the domain in the organization's Ad Hoc Components - Topics folder. In the permissions, I can see that the ROLE_USER and also the user who created the topic has the Read + Write + Delete right on the resource.
What could be an explanation is that the ROLE_USER and all other users have no right on the Topics directory. But even after assigning this right to the ROLE_USER, the directory did not get visible.
Therefore, I have really no clue why the user cannot see anything.
