Seam Value Expression and ui:include

[emsa]

Hi,

I have built a custom JSF Component where I need to resolve EL-expressions. I have used this code to do this:

Expressions.instance().createValueExpression(expression, String.class).getValue();

It works fine until I use a ui:include with ui:param, the aliased parameter is not resolved using the above expression.

Why? What is the correct way to resolve the EL expression?

thanks,

/Magnus

Use getValueBinding(expression).getValue()

But getValueBinding() (or getValueExpresseion()) returns the expression for a property - right?

I need to evaluate EL-expressions that are not properties - just 'random' expressions.

You'll need to build the expression using the local EL context/variable mapper. Ask on the facelets list.
