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#HMor... 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 -Vincent
