It works without a glitch (XE 2.7-SNAPSHOT.32908). I think it is more
elegant than tweaking CSS and doesn't compromise performance. Thanks!

The JavaScript code of this extension is evaluated (loaded into

Does this match your needs:
document.observe('xwiki:dom:loaded', function() {
// if the action on the current document is not view, don't load
annotations
if (XWiki.contextaction != "view" || !XWiki.hasEdit) {
return;
}
...// the rest of the code that loads the annotation feature.
});

In this particular case changing the JavaScript code that loads the
annotation feature is better IMO.
I tried but failed to do that.
Ricardo, did you check
AnnotationCode.Script ? I can see these lines at the end of the second
JSX (named "Annotation Javascript -- Annotation application"):
// if the action on the current document is not view, don't load annotations
if (XWiki.contextaction != "view") {
return;
}
I'm sure you can extend the test for your needs.
Hope this helps,
Marius
I think I get the point. Even though I'm not able to understand this
script now or how to tweak it, I understand that this option blocks the
loading process of the annotation feature. It is "cheaper" to do that as
it stops a process not required for a given type of users.
But, please, one more question. When is this script executed? Each time
a document is loaded or even reloaded?
Note that XWiki.hasEdit is defined in
javascript.vm .
And this is the reason why I'm not forced to
include xwikivars.vm in the
modified JSX. Please, am I right? I could use !$hasEdit, but then I must
include #template('xwikivars.vm'). I've tried and it seems to work fine.
Exactly.
Please, why don't directly use !$xwiki.hasAccessLevel('edit')?
To avoid (re)evaluating/recomputing the edit right multiple times (it
may be costly). The value returned by $xwiki.hasAccessLevel('edit') is
cached in $hasEdit to speed up the page loading time. $hasEdit
(velocity, server-side) is also send to the client side in the value of
the "hasEdit" property of XWiki JavaScript object.
Hope this helps,
Marius
Thanks!
