Hi Stefan,
there seems to be a bit of confusion regarding where and how convertors
are used.
Convertors are used in 3 places :
- In the definition datatype
- In the definition selection-lists
- In the binding
In these 3 places cocoon forms needs to make a conversion between a
native datatype and a string, in particular :
- In the definition datatype it's converting from the form field value
and its representation in the HTML, which is actually a string
- In the selection lists it's transforming between a java value and the
HTML select value, which is a string
- In the binding it's converting between the form field value and its
representation in the XML, which is again a string :)
As you can see, convertors are not used for selection list labels,
because a selection list is a Map (represented by a Map object in java,
a javascript associative array or an XML fragment) of value->label,
where label is already a String and does not need any conversion. When a
label is not provided, the value.toString() method is used.
So the problem is not in the convertor, but in the way you build the
selection list from javascript :
g_listData.receptionDate[i] = {value:element, label:element};
As you can see you are using the Date object both as value and as label,
the convertor only works on the value, you have to format the label
yourself in javascript. This can be accomplished in many ways, I can't
remember which facilities javascript offers but alternatively you can
use the common java SimpleDateFormat simply instantiating it with var
formatter = new Packages.java.text.SimpleDateFormat('dd.MM.yy'); and
then using as it java, formatter.format(element) IIRC.
Hope this helps,
Simone
