URL patterns

Hy,

I work with JSP&Struts on JBoss platform. For the add/edit actions over an item (product, user) The interfaces are parssed by the sitemesh decorator. I have an interface with a menu on the left of the page. For the view action I want a simple interface without a menu in a popup window, so a different decorator to utilize. The URL-s are the followings:

http://192.168.2.121:8080/forum-ejb/thecity/user.do?action=edit&userId=id1
http://192.168.2.121:8080/forum-ejb/thecity/user.do?action=view&userId=id1

So there is a single Struts action with the action parameter of different values. In decorators.xml I have defined the following patterns:

<decorators defaultdir="/jsp/decorators">
  <decorator name="thecity.viewUser" page="thecity/empty.jsp">

    <pattern>/thecity/user.do?action=view*</pattern> <!--doesen't work-->
    <pattern>/thecity/user.do*view*</pattern> <!--doesen't work-->

  </decorator>
  <decorator name="thecity.user" page="thecity/user.jsp">
    <pattern>/thecity/user.do</pattern>
  </decorator>
  <decorator name="thecity" page="thecity/default.jsp">
    <pattern>/thecity/*</pattern>
  </decorator>
</decorators>

I have tryed in 2 ways but doesen't seem to work. How should I solve this dilemma? I do not want to make a different action for the view action. Thanks.
