Re: Struts 2 losing timestamp in java.util.Date when validation failed

s Wed, 06 Jun 2012 14:08:38 -0700

Here's an JSPs, action class and struts.xml

http://localhost:8080/Sample/student_edit.action       calls form/jsp 
studentDetails.

Erase name and submit form, this will result in validation being failed.

This will erase timestamp from hidden field 
<s:hidden name="student.createdTimestmp"/>

If not validation error occurs, then it retains time.

Here's the trivial workaround:

* Create a minimally-failing example containing essentially identical JSP.
* Post it.

Whether or not your client wishes to admit it, it's unlikely any sort of IP
law would protect the usage of a hidden field and date render in an example
JSP.
