------------------------------------------------------------
I've upgraded project to use Spring Web 3.0.2:
<dependency org="org.springframework" name="spring-web" rev="3.0.2.RELEASE"
conf="compile,runtime->default"/>
The problem still exists. I've done a debugging session with 3.0.2 Spring
sources. What I could tell is that ServletRequestAttributes.setAttribute() was
hit from the code below:
org.springframework.web.context.request.AbstractRequestAttributesScope
public Object get(String name, ObjectFactory objectFactory) {
RequestAttributes attributes =
RequestContextHolder.currentRequestAttributes();
Object scopedObject = attributes.getAttribute(name, getScope());
if (scopedObject == null) {
scopedObject = objectFactory.getObject();
attributes.setAttribute(name, scopedObject,
getScope()); //calling here
}
return scopedObject;
}
I've attached the full stack trace from a debugger. My debugging session was a
bit funky - not all of the breakpoints were showing up as active, etc., but at
least this one was hit for the "app" bean.
I browsed around in Spring code. It looked to me that Portlet attributes might
come into play only for SCOPE_GLOBAL_SESSION, but the logic was a bit too
convoluted for me to grok it.
See org.springframework.web.context.request.FacesRequestAttributes:
public Object getAttribute(String name, int scope) {
if (scope == SCOPE_GLOBAL_SESSION && portletApiPresent) {
return PortletSessionAccessor.getAttribute(name,
getExternalContext());
}
else {
return getAttributeMap(scope).get(name);
}
}

> Key: PORTLETBRIDGE-127
> URL: https://issues.apache.org/jira/browse/PORTLETBRIDGE-127
> Project: MyFaces Portlet Bridge
> Issue Type: Bug
> Affects Versions: 1.0.0-beta
> Environment: WebSphere Portal 6.1.5 running on Windows XP Pro
> MyFaces Portal Bridge 1.0.0.beta2
> Reporter: DK
> Attachments: setAttribute() stack.txt, Thread Dumps.log
>
>
> I've been working on a POC application with PrimeFaces, deploying as a web
> app first, and then portalizing it and deploying to WebSphere Portal.
> When deployed as a web app, the following method removing JSF managed bean
> worked fine:
> public static void discardManagedObject(String objName) {
>
> FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove(objName);
> }
> It also seemed to work on the previous iteration of this app with IBM JWL
> Portlet Bridge 3.1.3.
> When deployed as a portlet with MyFaces Bridge 1.0.0.beta2, this does not
> seem to work anymore and the logic in code had to be changed as a workaround.
