Tries to evaluate an attribute as ValueExpression. If the attribute doesn't hold ValueExpression or the expression evaluates to null, the value of the attribute is returned.

Parameters:

attribute - the name of a component's attribute

component - the component

context - the context

Returns:

the evaluated ValueExpression for a given attribute or the value of the attribute (in case the attribute isn't ValueExpression or it evaluates to null)
