DynaActionForm form = (DynaActionForm)form;
String[] rrole = (String[])form.get("rrole);
Doing so, gives me the exception:

You might try using <html:multibox .../>

<c:forEach var="tk" items="${task}">
<html:multibox property="rrole"><c:out value="${tk.taskId}"/></html:multibox>
</c:forEach>
everything else you supose seems to work well, but I cannot look what 
the DVForm realy loaded,
how I will put these values into the database is an other story.

Thank you very much. Wolfgang

Subject: DynaValidatorFom with checkbox properties
Hi,
I have a checkbox, where do not know in adwance how many properties to 
be checked I will have
this is why I use forEach.
I am using a DynaValidatorForm which takes some attibutes for an 
employee. How shall I configure
the DynaValidatorForm in my strus_config to take a unknown number of 
checkbox values?

<c:forEach var="tk" items="${tasks}">
   
      <c:out value="${tk.taskBez}"/>
              <input type="checkbox" name='rrole' value='<c:out 
value="${tk.taskId}"/>'/>                   
     </c:forEach>

this is how my .jsp looks like.

second question: how can I make the properties of a DynaVForm available 
to a Action?

Thanks
   Wolfgang
