It seems to be very unstable.
I copied the code from working XWS.MySpace page (from windows dist.).
Then I created blank wiki page where I pasted the code and strip some
parts of the code away. First I strip the code for Public spaces listing
away and then page worked well. For one of my colleague I stripped the
code for My memberships away and listings worked but without My
memberships part, of course. For someone some of the code will work but
the same workaround does not work for everyone?!
I found that code parts for listings Public spaces and My memberships
produce errors.
Yesterday when some more spaces were created (16 registered users) and
All my spaces suddenly started to work.
I hope this will help you to catch the bug.
I strongly suspect that the NPE occurs when comparing two
com.xpn.xwiki.doc.XWikiDocument with "equals()", but I can't prove it and
know where exactly/under which conditions, as I still couldn't reproduce
it locally.
Anyway, I will provide a patch for XWS 1.2 M2 (Planned for Monday). You
will need to upgrade, as it will involve changes in the Java plugin (not
only the velocity code.)
Thanks for the help,
Jerome.

You are lucky : We reproduced the exact same error on one of our running

Hello Jarmo,
I could not reproduce this behavior on 1.1-m1 with a member account.
Something I don't understand in the exception you paste, is that it
refers
to a page in edition :
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'contains' in class java.util.ArrayList threw exception
java.lang.NullPointerException @ XWS.MySpaces49,100?
<http://www.prepost-test.com:8180/xwiki/bin/edit/XWS/49%2C100?parent=XWS.MySpaces&editor=wysiwyg>
Have you edited XWS.MySpaces ?
Can you give us a scenario to reproduce this error ?
Thanks for the feedback,
Jérôme.
Thanks for the quick answer. I am very new with Workspaces but I'll
found it very useful and like to use it.
No I have not done any changes to code or XWS.MySpace. I just installed
XWS couple of days ago.
When I was admin I did some users and these users did some new spaces.
Very soon I got this error listed below.
When I am admin I won't get any error when listing All my Spaces?! By
the way, admin has no spaces or there are no organization space yet.
Other users have spaces.
If someone found stable workaround for this I will adopt it right away.

Where I can find XWS.MySpaces? The link in your
mail produce empty
wysiwyg editor page.
Thanks,
