Thanks; that is clearer. Am I correct in assuming that the :
<fi:values>
<fi:value>1</fi:value>
<fi:value>3</fi:value>
</fi:values>
will be displayed as "checked input boxes" with a:
<fi:styling list-type="checkbox"/>
I still do not understand the rationale for this; this approach
effectively means two sets of calls to the database to generate the
output (1) to create the *possible* values as fd:item, and (2) to
create the values which appear as fi:item. While doing the first
is straightforward, doing the second will mean placing another
database call inside of the flowscript, yes?
Thanks again for the clear code explanation! An example like this in
the docs would be great.

Derek,
I think Joerg is making the following point: In the form *definition*,
you just define the set of *possible* values for a field, e.g.:
<fd:multivaluefield id="language">
<fd:label>Select language</fd:label>
<fd:datatype base="integer"/>
<fd:selection-list>
<fd:item value="1"><fd:label>english</fd:label></fd:item>
<fd:item value="2"><fd:label>german</fd:label></fd:item>
<fd:item value="3"><fd:label>french</fd:label></fd:item>
</fd:selection-list>
</fd:multivaluefield>
Then which fields are actually selected depends on the object you're
editing, i.e., must be set in the form's *model*. In flowscript:
var form = new Form("formdef.xml");
var model = form.getModel();
model.languages[0] = 1;
model.languages[1] = 3;
form.showForm("my-form");
This will yield the following form *instance*:
<fi:multivaluefield id="language">
<fi:label>Select language</fi:label>
<fi:values>
<fi:value>1</fi:value>
<fi:value>3</fi:value>
</fi:values>
<fi:selection-list>
<fi:item value="1"><fi:label>english</fi:label></fi:item>
<fi:item value="2"><fi:label>german</fi:label></fi:item>
<fi:item value="3"><fi:label>french</fi:label></fi:item>
</fi:selection-list>
</fi:multivaluefield>
So there is no need for a "selected="true"" or similar attribute on the
items of the selection list.
Cheers,
Johannes
