Hi All,
I'm having some problems with JPA and translators.
I have been able to set up a number of pages for CRUD, but in one class
I am using Joda's Time and Date library (specifically the DateTime
class). Now it came as no surprise that this class can't be used
directly from the HTML form and I would have to write a bit of code to
sort this out. So when I came to the page to create the Event Session
(session) I thought no problems I'll use a rtanslator, but I have been
unable to get the translator to work.
The problem appears to be that the translator doesn't get called, which
I can prove by using the debugger and placing a break point in both the
formatObject and parseText. As you can see below I call
ognl:session.startDate, which populates the form field with
2007-03-25T00:00:00.000+11:00, which is what I would expect for
DateTime.toString().
Can any one tell me why the translator may not be executed for
presentation (and possibly on submission)?
Thanks,
Below I have included some information from the relevant files:
------ HTML -------

<td><label jwcid="@FieldLabel" field="component:startDate">Start
Date:</label></td>
<td><input jwcid="[EMAIL PROTECTED]" displayName="Start Date:"
value="ognl:session.startDate" validators="validators:required"
translators="translator:dateTime" /></td><!--
,pattern=dd/MM/yyyy -->
</tr>
