date convertor in binding

[Michel Erard <er...@hta-bi.bfh.ch>]

Hello,

I've the problem that the convertor in my binding only works in one 
direction (Object --> Form). When I save back the input from my form 
into the object, the Date is passed as String like 01.01.2005 and not as 
Date Object.

<fb:context xmlns:fb="http://apache.org/cocoon/forms/1.0#binding"
            xmlns:fd="http://apache.org/cocoon/forms/1.0#definition" 
path="." >
    <fb:struct id='section1' path=".">
        <fb:value id="00001" path="questions[@name='00001']/response"/>
        <fb:value id="00002" path="questions[@name='00002']/response"/>
        <fb:value id="00003" path="questions[@name='00003']/response">
            <fd:convertor datatype="date">
                <fd:patterns>
                      <fd:pattern>dd.MM.yyyy</fd:pattern>
                </fd:patterns>
              </fd:convertor>
        </fb:value> 
    </fb:struct>
    <fb:struct id="section2" path=".">
        <fb:value id="00004" path="questions[@name='00004']/response"/>
        <fb:value id="00005" path="questions[@name='00005']/response"/>
    </fb:struct>
</fb:context>

The field response is type of Object. But this cannot be the misstake, 
because in the other direction it's working fine.
Does someone has a solution?

Regards,

Mike
