Re: Perspectives, multidomain and multi site issues
There are quite a few issues here. I will try to keep them separate.
About calendars. There are multiple calendars in Tiki. It would seem like you are using the one that presents the Tiki activity. There is also one that presents events, which is a special data type. I do not know if those made it into Tiki9, but there is also a tracker calendar plugin that can display events from the trackers feature.
If you have a problem with a link generated, please provide more details, like a screenshot that can indicate the problem more clearly.
About articles not respecting jails. Topics are not categories. They are an older form of content categorization. If you want to use category jail, you need to use categories, which can be set on articles.
As for listing wiki pages as articles, this is something that could be achieved using the PluginList. Worst case scenario, you might need to use a custom template file.
Did I miss anything?
