I've addressed this issue if anybody is interested.
Within each Stripes tag where I require EL expressions to be evaluated
I have added some condition logic within the setValue(Object value)
method. If the value appears to be an EL expression, i.e.
obj.toString().startsWith("${"), I call my own EvaluatorExpression
Class and evaluate the statement and set the Tags value attribute to
that value.
Seems to have done the trick...
