Sorry,
but I'm not able to get a query getting this:

I've found this...
http://extensions.xwiki.org/xwiki/bin/Extension/Get+Last+Comment
Coming from this thread...
http://xwiki.markmail.org/thread/qwnwzoa23ewdt64w
Sorry, I should have found it before!
it requires programming rigths, but this is not a
problem rigth now for us. What I'm not able to understand here is the role of
setLimit(1). Please, check this...
>>> setLimit sets the maximum number of
rows to return. In this case,

http://atriumkm.idisantiago.es/bin/ICT/ListCommentsWithProgrammingRights
We get the same result by using or not using it. Please, what am I missing here?
Also, whatever value I use for setLimit(), I
always get the first value in the list as ordered in the xwql statement.
>>> Maybe you changed the query in the

Thanks, Marius. No, I didn't change the query. Please, see this...
$services.query.xwql($xwlquery).setLimit(1).execute().get(0) First
$services.query.xwql($xwlquery).execute().get(0) First
Only First (comment) is displayed in both cases. The first code lines includes
setLimit(1) but the second one doesn't.
Please, where am I lost? Thanks!
It's simple. execute() returns a list:
['First']
['First', 'Second']
In both cases, the first item in the list obtained with get(0) is
'First'. There's nothing wrong with that. setLimit() sets the maximum
size of the returned list. In the first case the list has maximum one
element, and in the second case it has the size equal with the number
of matching rows found in the database.
Hope this helps,
Marius

I would not be hard to apply this query to all desired documents by looping through them.
Please, is this the most effective/economic in terms of process work way of doing this
query?
Thank you so much for your help!!!
