Re: SV: (bean-)property gets out of scope/session?

[Hien Q Nguyen]

or

<html:select size="13" property="subject">
        <html:optionsCollection              
                property="myCollection" value="key" labelProperty="label">
        </html:options>
</html:select>
You don't even have to specify value="key" and  labelProperty="label"   
if the bean in your array list has 2 properties "key" and "label" as  
Hakan said.

Take a look at the doc here:  
http://jakarta.apache.org/struts/userGuide/struts- 
html.html#optionsCollection

I'm using the collection attribute instead. The collection is an

of individual beans with properties "key" and "label".

Ämne: (bean-)property gets out of scope/session?
I'm fairly new to Struts, java and servlets so maybe it's a stupid  
question
but I have this problem:

Based on the pattern that is used by Steve Raeburn in his  
struts-examples, I
start my web-application with a prepareAction in which I declare
	ArrayList codering= new ArrayList();
	codering.add("NA");
	codering.add("NF");
	request.setAttribute("codering",codering);

I then forward to
        return mapping.findForward("success");
which redirects to Search.jsp

In Search.jsp I want to use this code:
      <html:select property="landCode" >
          <html:options name="codering" />
        </html:select><BR>
Tomcat however complains:
org.apache.jasper.JasperException: Cannot find bean under name codering
If I replace <html:options> with <html:option>-tags the Search page  
gives no
problem.

As far as I understand the Struts-architecture, request.setAttribute  
and
request.getAttribute are complimentory.
In his code-examples, I can't  find any directives that could serve to
include the bean (jsp:useBean?)

Maybe I'm overlooking something but who has any thoughts?
