RE: Null Date in a Contrib:Table
Thanks for your help Shing Hing Man. The ognl hint didn't work out for me but the following code did the job: component id=creationDateFormat type=Insert binding name=value value=myCreationDate/ /component In the corresponding getMyCreationDate() I let the method do the checking and formatting. It isn't perfect but it is ok for now. Another question: I'm into localization now but I can't figure out how Tapestry knows which language to display. I get german validation messages (I live in Germany) even if I change the language in the browser options to english. Is there any possibility to override this default behavior?

Re: Null Date in a Contrib:Table
Have you consider wrapping your component 'creationDateFormat' with an If component - so that the date is only rendered if it is not null ? There might be a drawback with the above approach. The default sorting on your date column might not work. Shing --- Manuel Thurn [EMAIL PROTECTED] wrote: Hi! For a project I want to display a list of objects in an html table.
