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.

RE: Null Date in a Contrib:Table
Posted by Manuel Thurn <ma...@isogmbh.de>.
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?

You could give the following a try.
<span jwcid="@If"
condition="ognl:components.table.tableRow.creationDate
!= null">
<span jwcid="createDateFormat"/>
</span>
The documentation on the If component is at

RE: Null Date in a Contrib:Table
Posted by Manuel Thurn <ma...@isogmbh.de>.
Thank you very much for your answer.
I realized that my attempt to format a null Date was the reason for the
exception. Without the formatting component (with the id
"creationDateFormat") an empty string is displayed.
Despite the possible drawback I'd like to try your suggestion. I would be
very happy if someone gave me a hint how to code the If component in
combination with the ognl syntax to catch the null Date.
Here again the mentioned code snippet:
<component id="creationDateFormat" type="Insert">
<binding name="value"
value="components.table.tableRow.creationDate.time"/>
<binding name="format" value="dateFormat"/>
</component>
