Re: Bean that returns Enumeration or Vector

[Erik Weber]

I assume by "bean" you mean form bean (ActionForm). I sometimes carry 
non-text attributes in form beans, but that data doesn't represent form 
inputs (which is really why a form bean exists) but maybe metadata 
associated with a form or with a form input. Typically those attributes 
will be collection fields (such as Vectors) that I will iterate using 
either c:forEach (or logic:iterate). Within the iteration I'll use c:out 
(or bean:write) to render properties of the objects in the collection. 
So, yes, it can be done. Using these fields in cooperation with a 
session-scoped form bean can really help when you've got a validated 
form that has a ton of metadata you need to display. I'm not familiar 
with any tags that operate on Enumerations, however.

To operate on the data, I use something like this:
<c:set var="details" scope="page" value="${myForm.someCollectionField}"/>
and
<c:forEach items="${details}" var="current">
 . . .
 <c:out value="${current.someProperty}"/>
 . . .
</c:forEach>
or simply
<c:forEach items="${myForm.someCollectionField}" var="current"/>
if you don't need to refer to the collection field anywhere but in your 
loop.

"myForm" would be the declared name of your form bean in struts-config.xml.

Hello,
I am trying to learn struts adn playing with some test code. I have a bean that 
returns an Enumeration for my view. but I cannot figure out how to get the data.
The two ways so far, have been to use the html:text and bean:write syntax.
Can I receive Objects other than strings back from a bean that is configured in 
the 'struts-config.xml' file? Any links to figure this out?
I am able to get normal strings back from the bean by using the following 
two techniques.
   <html:text property="name" />
 <bean:write name="menubean" property="something" />

Thanks,
Scott
