Portlets IndexOutOfBoundException

[huof]

Hi all,

I have a Webflow 2.2.1, JSF 1.2 (Mojorra) application in a portlet environment (jetspeed).

When adding the application I get the following error (and the portlet has no content, just its title-bar):
see file log.txt in log.zip.

I have no idea what the problem might be.
The following files are in the attached zip:
web.xml
portlet.xml
faces-config.xml
application-context.xml
portlet-config.xml
webflow-config.xml
webmvc-config.xml
main.xhtml (page)
main-flow.xml (flow definition)
PersonValidator.java ( a validator to be used)
ViewFlowHandler.java (returning the id of the view mode flow)

Would be nice if someone has a hint where the error comes from. I have no idea.

Regards,
Florian

Have you checked the swf-booking-portlet-faces sample in the distribution? Compare your faces-config.xml with the one in the sample.

The faces-config.xml looks the same.
So this cannot be the problem.

[Rossen Stoyanchev]

As far as I can see this is in your faces-config.xml:

<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>

And this is what's in the sample:

<view-handler>org.springframework.faces.webflow.application.portlet.PortletFaceletViewHandler</view-handler>

Sorry, my mistake.

Now I changed to the new view handler.
That still does not work.

The strange thing, from my point of view, is that in the exception it is still the

com.sun.facelets.FaceletViewHandler

that is included in the stack-trace:

        ... 82 common frames omitted

The full stacktrace, from deployment over adding the portlet to a page to the exception, can be found attached (log.zip).

Do you have an idea?

Addition:

I also tried with myfaces. the error is exactly the same.

I digged a little bit deeper.

The exception occurs in the getRendererViewId method of the FaceletViewHandler.

The method looks like

protected String getRenderedViewId(FacesContext context, String actionId) {
        ExternalContext extCtx = context.getExternalContext();
        String viewId = actionId;
        if (extCtx.getRequestPathInfo() == null) {
            String viewSuffix = this.getDefaultSuffix(context);
            viewId = new StringBuffer(viewId).replace(viewId.lastIndexOf('.'),
                                                      viewId.length(),
                                                      viewSuffix).toString();
        }
        if (log.isLoggable(Level.FINE)) {
            log.fine("ActionId -> ViewId: " + actionId + " -> " + viewId);
        }
        return viewId;
    }

The problem is now the creation of the viewId. the actionId that is passed to the method is (in my case)
/WEB-INF/flows/main/main/main
the lastIndexOf on viewId returns -1 and this results in a StringIndexOutOfBoundsException.

Further investigating...

Now it works

I added ".xhtml" to my files.
