Hi Vincent! Thanks for your answer!

Hi Ricardo,
There is one line here...
http://platform.xwiki.org/xwiki/bin/view/DevGuide/APIGuide
... that is making me nuts! This one...
SomeSpace.SomeClass[0] : field1 = "$rawValue"
I've been not able to make it work, whereas other syntaxes do. Here some
"life" Groovy examples....
http://portal.idisantiago.es/xwiki/bin/view/ICT/Groovy/
These 2 lines seem wrong:
objsAuthors = doc.getObjects('XWiki.XWikiComments').author
objsAuthor = doc.getObjects('XWiki.XWikiComments')[2].author
I can understand your explanation but, if these lines are wrong, why these
are working?

I'm not sure where I'm lost... :-(
Thanks!

Great! :)
Both XWiki sites and the web, in general, are
crowded with sites/pages
with
plenty of Groovy tutorials and manuals, but it
would be great to have
some
simple examples to helping understand the
similarities and differences
between Velocity and Groovy.
Please, is there any XWiki resource explaining, for instance, how to
achieve the same results shown in these sections by using Groovy?
There’s this doc that you may or may not have seen already:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Scripting
Please check in this doc the limitations of using groovy (programming
rights).
It’s easy to convert a velocity script in groovy in general since the
bindings are the same and all the API calls are actually calls on java
objects and thus are the same from all scripting languages.
Let us know if you have specific questions
doc.getObjects() will return a List of objects (i.e.
several), and there’s
no getAuthor() or get(‘author’) API on a Vector or List…
If you want to iterate you need to:
doc.getObjects('XWiki.XWikiComments’).each() {
def author = it.get(‘author’)
println “* ${author}"
}
I think the error is that in Velocity the call:
$doc.getObjects('XWiki.XWikiComments')[2].author is a shortcut and the
real call is:
$doc.getObjects('XWiki.XWikiComments')[2].get(‘author’)
See
http://velocity.apache.org/engine/1.7/user-guide.html#property-lookup-rules
This doesn’t exist in Groovy so you need to write get(‘author’).
Thanks

Thank you very much!
