[xwiki-users] Data-Types in UIExtension parameters
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?
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 $items)
"$item.replace('"',"")"
#end
{{/velocity}}

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.

I’ve updated the UIX Module documentation at
http://extensions.xwiki.org/xwiki/bin/view/Extension/UIExtension+Module#HMoreDetails
So yes, the parameters field can contain velocity.

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, “ ,”))
…
