Hi Roland,
Sorry for this very late late answer.
By now maybe you already know this. Anyway, just to be sure...
The CMS module can restrict the view of the documents per group, this is: users can only view the documents which viewer group is the same. So, if you belong to group A and one document is set to be viewed only by group C, then the CMS module won't show you that document.
What the CMS module don't do, is to display the documents by group. So, if you belong to group A and group B and there are one document for group A and other doc for group B, the CMS module will display them in the same listing.
In version 0.6.2, I'll add an option so the documents currently displayed are only those of the currently selected group. So, using the same example, the CMS will show you the document for the A group only when you have selected A in the group menu of Phprojekt, and the one for B when you select B from the Phprojekt menu.
Maybe I'm explaining something you already know, if so, sorry. I just want to be sure we are discussing the same thing.
If you have comments, suggestions or questions, Roland, don't hesitate to post.
Regards,
Mario A. Valdez-Ramirez
