 Could I do this in the params:

 label=abc

 target=Sandbox.try2

 icon=gerritjan.png

 test=$stringtool.split("item1, item2, item3", “ ,”)

 I tried to test it, but did not work? 
It won’t work because the parameter values are not typed, they are strings.

So if you have:

#foreach ($uix in $services.uix.getExtensions(…))
  #set ($params = $uix.parameters)
...
#end

then $params is always a String.

PS: Please always reply to the list ;)

  The velocity part was:

 #set($items=$extension.getParameters().get('test'))

  Hi

 I wonder if it is possible to use velocity data-types (Number, Date/Time, Array or List,
Object) in the parameters field of a UIExtension.

 I get the impression it is always considered as string and we have to do a conversion?  

 I’ve updated the UIX Module documentation at  
 http://extensions.xwiki.org/xwiki/bin/view/Extension/UIExtension+Module#HMo…

 So yes, the parameters field can contain velocity.  

  Following example (for a List of items in a
Array)

 cdls.try.abc has the following parameters:

 label=abc

 target=Sandbox.try2

 icon=gerritjan.png

 test=["Item1", 'item2', "item3"]

 {{velocity}}

 $services.uix.getExtensions("cdls.try.abc")

 #foreach ($extension in $services.uix.getExtensions("cdls.try.abc"))

 $services.rendering.render($extension.execute(), 'xhtml/1.0')

 #set($paramlist=$extension.getParameters().get('test'))

 #end

 paramlist is String?: $paramlist.class

 ##Would like it to be a list of items, but now I have to use velocity string functions to
create the list...

 #set($paramlistLengthMinusOne = $paramlist.length() - 1)

 #set($items = $paramlist.substring(1, $paramlistLengthMinusOne).split(","))

 #foreach($item in $items)     
 [snip]  

 That’s correct, UIX parameters are not typed (they’re strings).  

 However you can simplify a lot your velocity code.  

 In the UIX:  
 test=item1, item2, item3

 In the calling code:  
 #set ($paramlist = $extension.getParameters().get('test'))
 #set ($items = $stringtool.split($paramList, “ ,”))
 …

 Thanks
