page context
Hi!
Is there a way to register a bean from inside an Action, only for the
next response. I have data to display on a JSP page. But it will only be
needed for that page, so registering it to session seems an overhead to me.

Are you doing any kind of redirect?
Try printing the value of ${clist}, does this collection/list definatly contain data? because if
logic:iterate can't find the bean then it throws a JspException

Simpler solution is to write an Action for every resource; the
resource can have several views (usually JSP pages). This pattern is
easy with session-scoped form beans, so if you prefer to use
request-scoped form beans only, this solution is probably not for you.
For example, this New User Signup Wizard (this is just a demo, so you
can try to sign in) is controlled by one Action only. The intermediate
data is stored in session.

The normal pattern in Struts is to have a 'setup action' which loads any
data the page needs to display and then forwards to the JSP view, yes.

Sorry, my forward was defined as redirect="true". Now it works, thanks.
So one other question. Is is normal to write an Action for every page,
to register these variables.(no forms in page so far.) Or there is a
simpler solution?

I tried it but couldn't get it working. Here is my code:
Action:
request.setAttribute("clist", clist);
JSP:
<logic:iterate id="category" name="clist">
<tr>
<td><a
href="sunum.jsp?cid=${category.cid}">${category.name}</a></td>
</tr>
</logic:iterate>
ps: no it is not a form bean.
