PM> I'm not sure why this requires any changes to Unified EL, the change PM> is needed in JSF (see changes I suggested). Perhaps I misunderstood your feature request, then. Let me restate it in my own words and you can tell me if I understand you. You want to make it so the ExpressionFactory instance returned from Application.getExpressionFactory() is subject to the decoration construction pattern that we use for all the rest of our decoratable artifacts. Is that correct? The problem is that the JSF spec says the application must simply call JspFactory.getDefaultFactory().getJspApplicationContext(servletContext).getExpressionFactory(); We don't maintain a reference to the instance that is returned. Even if we started doing so, and performed the wrapping as an spec requirement of the javax.faces.application.Application implementation, you'd miss out on anyone who is creating expressions with the ExpressionFactory that you get from any other way than the Application instance. In other words, I assert that to satisfy your request, we have change the contract of how the canonical ExpressionFactory instance is created, which is currently the responsibility of the EL implementation.
