To follow up on Kathryn's post, I tried the sortproperty with dates and
that works too. So, if you do not want to write your own comparator, you
can do this:
- Add a field to your object like if currently you have String
dateString, add a field Date date and use the SimpleDateFormat class to
convert your String date to a Date object.
- Then, in the display tag definition, do this:
<display:table name="list" defaultsort="1" defaultorder="descending">
<display:column property="dateString" sortable="true" title="Date
Column Header" sortProperty="date"/>
</display:table>
This should work.
Good luck,
HC.

You can add another if clause in the comparator class that I posted a
few days back, to parse the two strings into Dates and return Date's
compareTo(). Or, you could write your own custom comparator.
I think you can also use two variables, with the display as String and
the underlying sort as Date, and use the sortProperty like another
poster did with numbers, but I am not 100% sure if that works with
dates.
