Re: very strange error with xwork.xml

OK, so we upgraded our local server and couldn't recreate the problem until we upgraded xml-commons, xml-commons-api and xerces-j2.  So the problem seems to at least be affected by these.

One I had the problem recreated I downgraded to WW 2.2.2 and tried out the same action.  It ended up throwing the same exception but with a couple before it.  Here is the stack trace:
[code]

[/code]

Again, I changed the action from:
[code]
      <action name="updateEmailBlast" class="com.paxfood.action.UpdateEmailBlast">
         <result name="success" type="chain">listAllEmailBlasts</result>
      </action>
[/code]

to:
[code]
      <!-- useless comment -->
      <action name="updateEmailBlast" class="com.paxfood.action.UpdateEmailBlast">
         <result name="success" type="chain">listAllEmailBlasts</result>
      </action>
[/code]

and the action works......

any ideas?
