Thxs god! xwiki is a wonderfull world ... when we manage to do what we want (or we can
understand javadoc) ... hum!
More seriously, thxs a lot for your help (I pulled my hair during all this week-end).
I wil probably add your nice code on this page:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/APIGuide#HAccessobjectsin…
## get the document which has the object (only one here) - this is the page where I can
see things in the object editor
#set( $MyDoc = $xwiki.getDocument("MySpace.MyNiceDoc"))
## get the document wich contains the class definition: this page has entries in the class
editor
#set( $class = $xwiki.getClass("MySpace.MyClass"))
#foreach($prop in $class.properties) ## go through all properties
* ${prop.prettyName} : $MyDoc.display($prop.getName())
#end
and
#set($MyDoc = $xwiki.getDocument("MySpace.MyNiceDoc"))
#set($class = $xwiki.getClass("MySpace.MyClass"))
## loop over all objects
#foreach($obj in $MyDoc.getObjects("MySpace.MyClass"))
## empty line is intentionally to create a new paragraph
Object number $velocityCount
#set($discard = $MyDoc.use($obj))
#foreach($prop in $class.properties) ## go through all properties
* ${prop.prettyName} : $MyDoc.display($prop.getName())
#end
#end

This code
(probably false) doesn't
work.
#foreach($prop in $class.properties) ## go
through all properties
*
${prop.prettyName} :
$doc.display($prop.getName())
#end
It
works for me if I do something like:
{{velocity}}
## get the
document which has the object (only one here) - this is the
page where I can see things in the object editor
#set( $adminDoc =
$xwiki.getDocument("XWiki.Admin"))
## get the document wich contains the class
definition: this page has entries in the class editor
#set( $class =
$xwiki.getClass("XWiki.XWikiUsers"))
#foreach($prop in $class.properties) ## go
through all properties
* ${prop.prettyName}
: $adminDoc.display($prop.getName())
#end
{{/velocity}}
This code should work for you 1:1 unless you
have deleted you "Admin" user. toapply for your
ise case you will have to adapt the name of the class and of
the document containing the objects
Note that there is a difference between:
- the document _defining_ the
class - for users this is XWiki.XWikiUsers and you can see
it at
http://localhost:8080/xwiki/bin/view/XWiki/XWikiUsers
and you can cnage it in the
class editor:
http://localhost:8080/xwiki/bin/edit/XWiki/XWikiUsers?editor=class
but this document is in itself a
user: the object eduitor is emprty:
http://localhost:8080/xwiki/bin/edit/XWiki/XWikiUsers?editor=object
(not completely empty, but does
not contain XWiki.XWikiUsers objects)
- the "admin" User document is not a
class:
http://localhost:8080/xwiki/bin/edit/XWiki/Admin?editor=class
but has a Users oject
attached:
http://localhost:8080/xwiki/bin/edit/XWiki/Admin?editor=object
Anyway, if
you have more than one object on a page, you will have to
loop over them and use "$doc.use".
the following works for me
(even though it is useless in this case, as is loops over
all users on a page, while there should be only one ...)
{{velocity}}
#set($adminDoc =
$xwiki.getDocument("XWiki.Admin"))
#set($class =
$xwiki.getClass("XWiki.XWikiUsers"))
## loop over all objects
#foreach($obj in
$adminDoc.getObjects("XWiki.XWikiUsers"))
## empty line is intentionally to create a
new paragraph
Object
number $velocityCount
#set($discard =
$adminDoc.use($obj))
#foreach($prop in
$class.properties) ## go through all properties
* ${prop.prettyName} :
$adminDoc.display($prop.getName())
#end
#end
{{/velocity}}
hth,
