Hi Christoph,
you can try this in the binding, using fb:javacript, for example
<fb:value id="id" path="id"/>
<fb:value id="fieldToHaveList" path="fieldToHaveList"/>
<fb:javascript id="fieldToHaveList" path="fieldOfTheBean" direction="load">
<fb:load-form>
// the "widget" var is the field reference in id="fieldToHaveList"
// Obtain the value of the widget what you need for populate the
// List
var id = widget.parent.getChild("id").getValue();
// then you can do what do you need for populate the list
// sentences write to continue
typewidget.setSelectionList( what you need );
</fb:load-form>
</fb:javascript>
this work is you write in the flowscript form.load(bean)
Cheers.
