WPS v6.1.0.2 +Seam 2.2.1-SNAPSHOT + JPBP 2.0 alpha = NPE

[titou09]

I'm currently testing JPBP 2.0 + Seam 2.2.1-SNAPSHOT + WebSphere Portal v6.1.0.2 en WebSphere v7.0.0.5 + facelets

When the page containing my very simple portle (1 form, inputText, 1 commandButton) with one Seam component I receive the folllwoing exception:

00000063 ApplicationMg A WSVR0221I: Application started: PA_Ports_Denis_Seam

The code fails in seam on this line (Pages.java:543):

return ( (HttpServletRequest) request).getRequestURL().toString();

Any clue?

What does your web.xml look like?
Do you have this in it:

<context-param>

 <param-name>javax.faces.LIFECYCLE_ID</param-name>

 <param-value>SEAM_PORTLET</param-value>

 </context-param>

In fact, in the Pages.getRequestUrl() method, the facesContext.getExternalContext().getRequest() is not null, but facesContext.getExternalContext().getRequest().getRequestURl IS null...

a request.toString() displays the following:

In the JSR-286 specs, section PLT.19.3.3 it is stated that

The following methods of the HttpServletRequest must return null: getRemoteAddr,getRemoteHost, getRealPath, getLocalAddress, getLocalName, and getRequestURL

It seems normal that request.getRequestUrl() return null in .
So is this a bug in seam? in the bridge?
Is the bridge supposed to solve this and provides/mock/fake something valid for getRequestURL() ? or maybe the path/stack used is not correct?

dennis,

i am getting all sort of errors unless i use the seam2.2CR1 jars, anything else just cause problems.

any help is appreciated

I have only a very simple app to test WAS v7.0.0.5 + WPS v6.1.0.2 +Seam 2.2.1-snapshot + PB 2.0.0 and it works fine
I patched the org.jboss.seam.navigation.Pages.getRequestUrl() to returrn null if request.getRequestURL() is null as I'm waiting for PBR-117 to be investigated and sorted out
what kind of problem do you have? what AS are you using?

[lpiccoli]

hi dennis

i am using jboss 4.2.6 with jbossportal2.7.2.

when using seam 2.2.0GA i get the existing page returned when accessing a s:link, instead of the requested link page.

i gave up and went back to portletbridge.1.0.0CR but it only seems to work with Seam2.2.0CR1, when i use Seam2.2.0GA it throws 'No Active Context' errors when accessing s:link.

u got any thought on why seam 2.2.0GA doesnt work the same as seam2.2.0CR1?
