Wasn't this the origional purpose of the validation
attribute added to Beta1 class properties?
3 options:
1. Make a javascript that checks this. There is already
one that checks the document content, you can add there the title check.
2.
Modify the com.xpn.xwiki.web.SaveAction to refuse documents without a title.
This should be configurable, as not all users want this. You can then submit a
patch, so that we can integrate it in the trunk.
3. Make a JIRA issue ( http://jira.xwiki.org/ ) requesting 2, if you
don't have the time to implement it. Maybe somebody else has some spare
time.
