I am in the process of redesigning a project and I've come across what I think is a bug but Im confused as to where the bug is originating from.
Basically all I am trying to do is pass a URL parameter to the backing bean. Nothing magic and there are loads of different ways of achieving this. The following are the ones I use regularly;
- I can change the bean from @Named to @ManagedBean and then use the @ManagedProperty
- I can access the param using
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap()and then get the desired param from the Map - Or I can use:
<f:metadata><f:viewParam name="id" value="#{backingBean.id}"/></f:metadata>
When I'm using JSF 2.1 with Glassfish 3+ all three of these work perfectly. The problem is that my current project is using JSF 2.2 and Glassfish 4 and none of these work! No matter what I do the parameter is never set and always just ends up as null.
I'm not sure how to track this down further. The obvious changes from the last project are that I am using Glassfish 4 instead of 3, JavaEE 7 instead of 6, and JSF 2.2 instead of 2.1. I don't get any errors or exceptions that I can post.
Is there anything else I can test or any alternative solutions I can try. Failing that is anybody aware of any reported bugs or changes that might cause this. Lastly can anybody reproduce this error?
