As now Nuxeo is using 3 or 4 different ways to resolve expressions:
- standard EL resolution through the JSF context (using facelet, jboss-el and SeamELResolver, and sometimes seam function mapper wrapper) in layouts and content views
- a pseudo JSF EL context in audit (through nuxeo-platform-el)
- jexl in actions (including a hack to partially resolve some Seam components)
- mvel in operation/automation
As this kind of ELContext is needed for layouts on gwt and content views on the core side, it would be good to define a generic interface for EL resolution.
