> From MYFACES-3053 "user should see not just a cryptic stack trace, but the EL
> expression that was being evaluated including the part of the EL expression
> that triggered the problem"
> Myfaces utilize TagValueExpression and TagValueExpressionUEL as
> TagAtrribute-aware wrappers around EL ValueExpression. But this "context" is
> only .toString() of TagAttribute and that prohibits user-frendly formatting
> of messages.
> Provide TagAttribute instance, create TagAttributeAwareExceptionWrapper that
> will hold this instance. Clients (mainly ErrorPage) can read attributes of
> TagAttribute and format it as necessary, for example "EL expression that
> triggered the problem: " + wrapper.getTagAttribute().getValue()
