Re: cforms custom binding multivaluefield

[Jorg Heymans]

setting the multivaluefield datatype to integer did the trick. I guess 
it is the "key" (or value - depends how you look at it) datatype that 
matters here, not the label.

Hi,
I have a bean called "Profile" that populates my form. The bean has an 
arraylist called "targetGroups" which contains "TargetGroup" objects. 
(and get-set methods for this arraylist)
Each Targetgroup object has an id(Integer) and name(String).

i have a multivaluefield widget for these groups
<fd:multivaluefield id="targetgroups">
<!--is this datatype correct???? tried setting it to my TargetGroup 
class but it says unknown datatype -->
  <fd:datatype base="string"/>
  <fd:selection-list/>
</fd:multivaluefield>

I want to populate this multivaluefield with a custom binding
<fb:javascript id="targetgroups" path="targetGroups" direction="load">
  <fb:load-form>
    var collection = jxpathPointer.getNode();
    widget.setSelectionList(collection, "id", "name");
  </fb:load-form>
</fb:javascript>
I am getting a ClassCastException
