Hi Jeromy,

Ah, I see the problem better now. In your select:
<s:select multiple="true"
name="myObjects"
list="myObjects" listKey="id" listValue="name" />
you're trying to access myObjects as both a list of objects (list=) and
as a string (name=). You can't do what you're describing because
convertToString needs to provide the currently selected value for the
select.
I presume you don't really mean that, but rather want:
<s:select multiple="true"
name="mySelectedObject"
list="myObjects" listKey="id" listValue="name" />
where mySelectObject is the same class as the elements in the list, and
type conversion ensures that the select contains id:name and sees just
the selected object loaded from persistence and provides a list of
objects loaded from persistence (no handling of strings what-so-ever).
Sorry, now I see that my example was misleading. Let me try again:
F.e. I would want to display a list of myObjects, and a "multiple"
select box where you can modify the list.
List:
<s:iterator value="myObjects" var="o" >${o.name}</s:iterator>
Select:
<s:select multiple="true" name="myObjects" list="availableMyObjects"
listKey="id" listValue="name" />
This way, the iterator would need to get a collection from
getMyObjects() (without type conversion), but the select would send IDs
which needed to be converted.
Now the funny thing is that this seems to work. I got all sorts of
exceptions at first, but they don't seem to be related to conversion.
Thanks for all your help, and I'm sorry for wasting your time on this
one. I'll get back when I find the real problem, should it be related to
struts.
