------------------------------------

This is the exception I get any time I attempt to call a function from a valueBinding (method bindings work fine via Facelets, but not JSP)

>             Project: JBoss Seam
>          Issue Type: Feature Request
>    Affects Versions: 1.2.1.GA
>            Reporter: Chris Rudd
>
> Currently the expression language extensions are only available from facelets views. If the Faces Application is hooked into then the createMethodBinding/createValueBinding can be extended to support the extensions as well.
> The issue is that currently you cannot do this :
> FacesContext.getCurrentInstance().getApplication().createValueBinding("#{s:hasPermission('g','g',null)}");
> Likewise if you are in a faces request this also failes (due to it delegating to the facesContext)
> Expressions.instance().createValueBinding("#{s:hasPermission('g','g',null)}");
