> Hi,
> So I'm trying to understand a little bit better the way type conversion is supposed to
work in struts 2/Xwork 2 and I really don't get it. The part I am missing is when is that
conversion applied, and on what basis?
> My use case is an action that must present a select box containing dates. So hoping to
have struts 2 do all the heavy lifting, I create my action with a field
> private List<Date> theDates;
> fills it with the right date and render it on the JSP :
> <s:select list="theDates" name="theDate" />
> I have a field on my action to receive this date parameter :
> private Date theDate;
> The problem is that the generated HTML content is :
> <select name="theDate" id="index_theDate">
>     <option value="Mon Jul 13 15:01:21 EDT 2009">7/13/09</option>
>     <option value="Sun Jul 12 15:01:21 EDT 2009">7/12/09</option>
> </select>
> What I don't get is that the body of the option has been correctly converted, while the
value is not at all converted (that looks like a simple toString to me). So of course, the
conversion from the toString version of the date to a date object is failing.
> Now I don't get what I did wrong there, and how this is supposed to work. Definitely
this looks wrong to me, cause the value is the most important thing in the option. But I couldn't
find a way of getting that converted.
> Any advise?
> Thanks for any help.
