[imp] no answer on invitations in basic view?!

[Christopher Neuhaus]

Hi List,

has anyone recognized the problem, that there is no posibilaty in basic 
view to react on an event invitation?!

Here is the form (in the invitation-mail), which gives the user the 
ability to handle the request:

<label for="action_0" class="hidden">Aktionen</label>
<select id="action_0" name="itip_action[0]">
  <option disabled="disabled" value="">-- Auswählen --</option>
  <option value="accept-import">Anfrage akzeptieren und in meinem 
Kalender aktualisieren</option>
  <option value="import">In meinem Kalendar aktualisieren</option>
  <option value="accept">Anfrage akzeptieren</option>
  <option value="tentative">Anfrage vorläufig annehmen</option>
  <option value="deny">Anfrage ablehnen</option>
</select>


Live HTTP-headers tells me:

But nothing happens.

Can it be, that there is a problem with 
imp/lib/Ajax/Imple/ItipRequest.php or imp/lib/Mime/Viewer/Itip.php?

The Problem is recognized by M$- and Linux-Clients in Chrome and Firefox.

Best Regards
