Also, make sure that the action in which you attempt to get the "rrole" value
from is declared to use the correct form. 

If you can, please post your action mapping as well.

Now it is time to apologize. I have a classes and a src cirectory for 
compiling with ant,
in both is a struts-config.xml, guess what. I altered the config file 
in the src directory,
I will immediately kill the evil struts-config in the wrong directory.
Please do not tell anybody of my stupid fault.

And most of all: Thank you ver much, now everthing works fine.

regards
   Wolfgang

The exception indicates that you have not defined a property named "rrole" in your form.

What does your form-bean declaration look like in your struts-config file?

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

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
