Hello All,
Thanks to Henning, that was the solution:
#createForm ("forumnotes" "post" $link.setAction("Notes").toString()
$link.setPage("forum,NotesList.vm").addPathInfo("topicid",
$topic.FtId).toString())
the result is:
<form name="forumnotes" method="post" Accept-Charset="ISO-8859-2"
action="http://localhost:8080/portal/servlet/portal/action/Notes"; >
<input type="hidden" name="nextScreen"
value="http://localhost:8080/portal/servlet/portal/template/forum%2CNotesList.vm/topicid/4";>
with toString() it doesn't duplicates, and can be direct parameter!
