[Kss-devel] Weird behaviour with kssSubmitForm and empty selects

[Martin Aspeli]

Hi,

I have this TAL in oi.plum:

<select size="1" name="stream" id="addDeliverableStream">
                         <option
                             value=""
                             i18n:translate="stream_select_header"
                             style="font-weight: bold; border-bottom: 
solid black 1px;"
                             >Stream</option>

                         <option tal:repeat="stream view/streams"
                             tal:content="stream/title"
                             tal:attributes="value stream/cmf_uid;
                                             selected 
python:request.get('stream', None) == stream.cmf_uid() and 'selected' or 
None"
                             />
                     </select>

That first <option /> is a "label" (no space for an actual label) that 
submits an empty string. You're meant to pick something else in the list.

This works fine with the non-KSS form handler, which gets 
self.request.form['stream'] == "".

I then have this KSS:

#addDeliverableButton:click {
     evt-click-preventdefault: true;

     action-server: addNewDeliverable;
     addNewDeliverable-kssSubmitForm: currentForm();
}

In the addNewDeliverable action, I get self.request.form['stream'] == 
'Stream'. It works fine if I select a value, but when the value is "", 
it seems I get the select *label* and not the value.

I suspect there's some code like:

  if not value:
      value = label

but ... that's wrong. ;-)

Or no?

Martin
