Access ManagedBean from Validator

[Dominik Müller]

Hi Together,

in some Tutorials is explained how to access a attributes of managedbean in source code:

    
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().getELResolver().getValue(
    fc.getELContext(), null, "personList");

My Problem is, that eclipse throw an Error when trying to insert it into an Validator-Class

    
The type javax.el.ELResolver cannot be resolved. It is indirectly referenced from required .class files

Some Ideas?

thanks a lot
Dom

Yes. That's doing it the hard way. You'd do that if you needed access to stuff at the EL level.

The easier way is to take advantage of the fact that managed beans are scoped POJOs and access them as session or request attributes. You still need the FacesContext, but instead of looking for the EL Resolved, dig into the FaceContext's J2EE objects.

I normally provide a set of utility classes for that kind of work so I can keep the actual FacesContext references out of my backing beans, It insulates me from possible future changes and makes the backing beans more portable.
