Description

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.
