Re: pass bean as parameter to JSP

David,
As Matthias points out below, you cannot use JSF html tags inside of
c:forEach. That's not only bad style, but it won't work as
you expect,
at least until JSF 1.2.
I guess you are inside of JCP-JSF-Group, isn't it?
So my question:
-JSF 1.2 will be included into J2EE 1.5 (aka J2EE 5)?
I don't know when JSF 1.2 will be ready, but containers that support 
J2EE 1.5 must supply a JSF implementation.

thanks,
Matthias

Btw. looked at Oracle's ADF Faces?
<af:forEach/> will enable you to do things like
this in *good old* jsf-manner
:)

<c:forEach var="myVar" items="${myComp.myVectors}">
 <c:set value="${myVar}"
var="myVarAsManagedBeanDefinedInFacesConfig"
scope="myScope" />
 <h:outputText
value="#{myVarAsManagedBeanDefinedInFacesConfig.foo}"/>
<managed-bean>
<managed-bean-name>myVarAsManagedBeanDefinedInFacesConfig</man
aged-bean-name>
<managed-bean-class>ClassOfMyVar</managed-bean-class>
<managed-bean-scope>myScope</managed-bean-scope>
</managed-bean>
works without any problems :-)

Hendrik

Heath means that you can't do things like:
<c:forEach var="myVar" items="${myComp.myVectors}"> <h:outputText
value="#{myVar.foo}"/> ... </c:...>
Hans Bergsten wroten a nice article
on that (and other things):

I don't think you can use JSF tags inside a JSTL forEach tag.
A managed bean specified in the faces-config is - afaik -
a more or
less normal jsp bean, reachable for all JSTL Tags, therefore you
can do this (let's say myComp is a managed bean, specified in the
faces-config):
<c:forEach var="myVar" items="${myComp.myVectors}">
<c:set value="${myVar.hashCode}" target="${tempBean}"
property="tempHashValue" />
If you're instancing objects with the c:forEach-Tag and
want to use
one of them as a managed bean (to do value binding etc.)
you'll need
to set reference correct:
<c:set value="${myVar}" var="managedBeanDefinedInFacesConfig"
scope="myScope" />
Mabe it is not 100% standard conformable but belive me it
works -
I'm doing exactly this in my project with your MyFaces without
having any troubles.

Hendrik
