[xwiki-devs] strange behaviour when modifying an DBStringList prop in an object from a velocity script

hello guys, I do the following: - I have a class with a DBStringList property "mylist" - In a velocity script, I do: #set($obj = $doc.getObject("MyClass", $mynb) #set($mylist = $obj.get("mylist")) #set($mylist = "${mylist}|${mynewlistitem}") #set($ret = $obj.set("mylist", $mylist)) #set($ret = $doc.save()) - I run this script and I can see in the DB that "mynewlistitem" was added as listitem to "mylist" but the item doesn't appear in the object editor for property "mylist" in my document. - Moreover, I get some rendering exception in contentview.vm when I try to access this object in other velocity scripts. - When I create the link using the Object editor, then everything works well but I don't see anything different in the DB from the previous state. - I have tried the same with: #set($obj = $doc.getObject("MyClass", $mynb) #set($mylist = $obj.getProperty("mylist").getValue()) #set($ret = $mylist.add("${mynewlistitem}")) #set($ret = $doc.save()) same result... It seems the Object property is saved but it is not taken into account by the object in the document. Do you any clue for me? regards Pascal
