Hello,

for authoring template code like:

## You can modify this page to customize the presentation of your object. ## At first you should keep the default presentation and just save the document.

#set($class = $doc.getObject('Book store.AuthorClass').xWikiClass) #foreach($prop in $class.properties) ; $prop.prettyName : $doc.display($prop.getName()) : $prop.getName() #end

is used by default. I need to modify this to extract some of the properties of the object and set it to the Xwiki context to be passed into another scripts, but besides #foreach I'm not able to extract individual properties from the properties collection by any possible way. Some of things I tried was (in my case I'm interested in "name" property)

$class.properties.name $class.properties["name"] #set ($props = $class.properties) $props $props.name $props.get("name") $class.properties.getName() ($($class.properties).getName())

Keep in mind that there are real Java objects behind these variables, and you can check the Javadoc (and even the source code) of those objects. Printing $class.class reveals that you're dealing with an object of type com.xpn.xwiki.api.Class, and checking the API at http://platform.xwiki.org/xwiki/bin/view/DevGuide/API shows that the method you're looking for is: $class.get("name") And it's a feature of Velocity to automatically try to use a "get" method when a more specific method is not found, you can even do: $class.name Looking at what $class.properties returns, you can see that it's an array of properties as in Element[], so you can't retrieve properties by name from there.

but so far w/o any success. On the other hand the code like:

#foreach($prop in $class.properties) #if ($prop.getName() == "name") I FOUND THE NAME PROP! #end #end

is working well, but is not that elegant as if properties would allow kind of map usage...

Any help on this is highly appreciated.
