If the script is called from Main.ChildDoc and ChildDoc has a parent called ParentDoc

Velocity sees ${doc.parent} and replaces with Main.ParentDoc before the query ever reaches
the database.
The doc.id was a mistake and the line should read
#set($results=$xwiki.searchDocuments("where doc.hidden = false and
doc.fullName='${doc.parent}'
order by doc.title asc"))
But we should all get in the habit of avoiding the dynamic building of queries because it
can be a
security issue. Think if doc.parent = "'; drop table xwikidoc;" Hibernate
won't allow that but there
are sometimes ways to fool even Hibernate.
Best practice for query security is to use:
#set($results=$xwiki.searchDocuments("where doc.hidden = false and doc.fullName=?
order by doc.title
asc", [$doc.parent]))

Hello,
Sorry for the delay in reply.
Sergiu, that was the case. Thank you very much. :)
Ricardo, the query is to include a list of all child documents in order. I
included the curly braces in the query simply because I find it easier to
read.
Thanks, Chris. Far clear the reason to use curly braces, but I am not
able to understand the query. If I understand well, it lists all
documents with a given patent. Thus...
{{velocity}}
#set($results=$xwiki.searchDocuments("where doc.hidden = false and
doc.id='${doc.parent}' order by doc.title asc"))
#foreach($item in $results)
#set ($itemdoc = $xwiki.getDocument($item))
[$item>$item],
#end
{{/velocity}}
must list all documents having ${doc.parent} as parent. So, included in
a page ICT.WebHome, must list all child documents having ICT.WebHome as
parent, mustn't it?
Well, I get nothing by including this snippet in such ICT.WebHome page.
And there are 50 documents that have this age as parent page!
Please, where am I wrong?
One more things. Please, how is it possible to compare doc.id and
$doc.parent? As far as I understand, doc.id maps to XWD_ID in xwikidoc
table (it is a bigint(20) field). And $doc.parent invokes getParent()
and gets a string in the form Space.Document. Thus, how is it possible
to compare both values?
Thanks for your help!
Thank you,
Chris

Please, Chris, what this query is designed for? And why do you use
curly
braces to wrap doc.parent?

There are two types of titles.
Document titles are stored in the database as the doc.title field, and
they are editable in the editor above the content.
Display titles are computed from the document title, first heading from
the content, or the document name, depending on which one exists, in
this order. Unfortunately it is not possible to see the display title in
queries.
I'm not sure, but I think that your problem is caused by this difference
between display and document titles. The first set of documents has an
empty document title, but in the UI you see their computed display
title. The second set of documents is correctly ordered by their
persisted document title.
