[opencms-dev] Problem with explorer view in online project

[Laurent Gauthier]

I get a strange behavior with the online project.

The explorer pane shows nothing and actually, a Javascript error
appears:

>>>Error: 'tree.nodes[...].parent.id' is null or not an object.
>>>Code: 0
>>>URL: .../opencms/opencms/system/workplace/action/index.html

In other words, the javascript is not able to build the folder tree
because it does not receive anything. In fact, the source for the
explorer pane is as so:
...
<!-- begin of folder tree -->

<!-- end of folder tree -->
...

The online content is visible however and the offline projects show the
folder tree as expected.

The VFS tables appear OK (the database is not corrupted).

Anybody have an idea on how to fix this?
