Hi Matthias,
the problem is that if loaded via HQL the objects do not come with all their
properties loaded; but you can load them by extending the HQL query:
{{groovy}}
hql ="select obj, prop from BaseObject as obj, StringProperty as prop where
obj.className='MySpace.MyClass' and obj.id=prop.id.id and
prop.name='MyProperty'"
results = services.query.hql(hql).execute()
println "|= Title |= Value"
results.each { item ->
println "|[[${item[0].name}>>${item[0].name}]]| ${item[1].getValue()}"
}
{{/groovy}}
(This is assuming that 'MyProperty' is actually a StringProperty, and not e.g.
a DateProperty)
There is more about it on the Query Module page:
http://extensions.xwiki.org/xwiki/bin/view/Extension/Query+Module
Hope this helps,
Clemens
BTW, for me the "magic query completion" that e.g. make the HQL-query
containing the empty string list all documents in the current wiki does no
longer work, while it is given as example in the documentation. A "where 1=1"
works flawlessly however. Is this just me?

Mostly you did, but something has eaten the closing quotes of the println
statements. Pretty easy to find this out, however ;)
