[xwiki-users] Clear the value of xwiki properties used on a form

Hi, I have an XWiki object with properties. I am using the object in a html form to apply XWiki style validation as described in * http://platform.xwiki.org/xwiki/bin/view/DevGuide/Creating%20a%20form%20wit… *. I am setting some properties (* com.xpn.xwiki.objects.classes.StaticListClass) dynamically. Like this:* * * * valdoc.getxWikiClass().get(propertyName).getPropertyClass().setValues(value) * *valdoc.save()* * My problem is that the properties of the object preserve its value between accesses to the page that contains the form. So when I go to the page that contains the form the first time everything is ok, but on subsequent accesses to the page some properties already have a value. I tried to clear the value of the properties using:* * * * valdoc.getxWikiClass().get(propertyName).getPropertyClass().setValues("") valdoc.save() * * * *But strangely that leaves the last selected values.* * * *I though that I could change the selected value of the staticList property. But I couldn't find out how to do that.* * * *I have two questions:* * * *1. How can I clear the value of those properties?* *2. How can I set the selected value(s) of a List property?* * * *Abel* * * * *
