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 $items) <h1>"$item.replace('"',"")"</h1> #end {{/velocity}} Gerritjan Koekkoek Vader van Rai Koekkoek (cdls) en voorzitter vereniging CdLS Visit our website<http://www.cdlsworld.org> Facebook<https://www.facebook.com/gerritjan.koekkoek> email&lt;gerritjan(a)cdlsworld.org&gt;
