webdav update still broken for kde4.4 kontact client

[sam]

I just wondered if sync works for the kontact from the latest kde4.4 and 4.5 releases. Earlier, there was a bug with missing "last_modified" field, which prevented event updates work. Ok, I tried it with newer 4.4 & 4.5 versions, the "last_modified" field is really included within update request now but updates stil do not work. I can read all events and add new events but still cannot edit/modify existing ones. Huh ?

Looking more into detail, there seems to be some problem with the folder_id field.
One can see following in the log:

SEVERE: WEBDAV-0001 Category=8 Message=Invalid value in element "folder_id": . exceptionID=-606037176-16051

So lets look at wireshark data:

If we read the event by Kontact we get following from the ox-server:

<?xml version="1.0" encoding="UTF-8"?>
<D:multistatus xmlns:D="DAV:" version="6.18.0-Rev7" buildname="Open-Xchange"><D:response xmlns:D="DAV:" 
xmlns:ox="http://www.open-xchange.org">
<D:href>400</D:href>
<D:propstat><D:prop>
<ox:object_status>CREATE</ox:object_status>
<ox:start_date>1291461300000</ox:start_date>
<ox:end_date>1291468500000</ox:end_date>
<ox:location>here</ox:location>
<ox:full_time>false</ox:full_time>
<ox:shown_as>1</ox:shown_as>
<ox:alarm_flag>false</ox:alarm_flag>
<ox:uid>20ce8d61-6cf2-4cb3-a486-972aa46111e7</ox:uid>
<ox:color_label>0</ox:color_label>
<ox:title>test</ox:title>
<ox:participants><ox:user ox:confirm="accept" ox:external="false">62</ox:user></ox:participants>
<ox:created_by>62</ox:created_by>
<ox:creation_time>1290952521000</ox:creation_time>
<ox:modified_by>62</ox:modified_by>
<ox:last_modified>1290953916455</ox:last_modified>
<ox:object_id>400</ox:object_id>
<ox:folder_id>225</ox:folder_id>
<ox:private_flag>false</ox:private_flag>
</D:prop><D:status>200</D:status>
<D:responsedescription>OK</D:responsedescription>
</D:propstat></D:response>
</D:multistatus>

Ok, so we got the folder_id = 225.

An now the update request from Kontact:

<?xml version="1.0" encoding="utf-8"?>
<D:multistatus xmlns:D="DAV:">
 <D:propertyupdate xmlns:D="DAV:">
  <D:set>
   <D:prop>

    <ox:client_id xmlns:ox="http://www.open-xchange.org">KResources_SLOX_Event_400</ox:client_id>
    <ox:last_modified xmlns:ox="http://www.open-xchange.org">1290952521420</ox:last_modified>
    <ox:title xmlns:ox="http://www.open-xchange.org">test1111</ox:title>
    <ox:note xmlns:ox="http://www.open-xchange.org"/>
    <ox:alarm xmlns:ox="http://www.open-xchange.org">0</ox:alarm>
    <ox:categories xmlns:ox="http://www.open-xchange.org"/>
    <ox:folder_id xmlns:ox="http://www.open-xchange.org">225</ox:folder_id>
    <ox:start_date xmlns:ox="http://www.open-xchange.org">1291461300000</ox:start_date>
    <ox:end_date xmlns:ox="http://www.open-xchange.org">1291468500000</ox:end_date>
    <ox:location xmlns:ox="http://www.open-xchange.org">here</ox:location>
    <ox:full_time xmlns:ox="http://www.open-xchange.org">false</ox:full_time>
    <ox:recurrence_type xmlns:ox="http://www.open-xchange.org">none</ox:recurrence_type>
   </D:prop>
  </D:set>
 </D:propertyupdate>
</D:multistatus>

...written the same folder_id=225 back we got before and it is invalid ?

Huh ??? Whats wrong here ? An OX server bug ?
