Dear all,

I have a class with a UserList attribute. I am trying to add users to

The UserList property is not that well maintained, and actually it does not use a list internally. The actual data type inside is the LargeStringProperty, which is a string (the same as TextArea). You should instead use a DBListProperty, which is maintained and should work as expected. The following code (and corrections) should work with a DBList property only (also, only if Multiple select and Relational storage are checked for the property, since otherwise you'd also get a LargeStringProperty instead of a list).

this list from an other page with no success. I try using the following code :

#if($joinTask!="")  #set($taskDoc = $xwiki.getDocument("Project.${joinTask}"))  #set($taskObj = $taskDoc.getObject("XWiki.TaskClass"))  #set($list = $taskObj.get("assignedPeople"))

$taskObj.get doesn't return the internal value of the property, but it actually displays the value as HTML. The right approach is: #set($list = $taskObj.getProperty('assignedPeople').value) Now $list is a real java ArrayList, so the next code will work.

 $list.add($xwiki.getUser())  $taskObj.set("assignedPeople", ${list})

^ This is not needed, the list is already the property value. It's enough to save the document.

 $taskDoc.save() #end

but $list.add does not exist so I tried differently :

#if($joinTask!="")  #set($taskDoc = $xwiki.getDocument("Project.${joinTask}"))  #set($taskObj = $taskDoc.getObject("XWiki.TaskClass"))  #set($list = $util.getArrayList())  $list.add($xwiki.getUser())  $taskObj.set("assignedPeople", ${list})  $taskDoc.save() #end

but I have a casting exception.

I had a look on the velocity website, on this list archives,... with no success

My question is : Can I add users like that or the only way is through the edit panel and if yes, what is my mistake ?
