More generally, I can't see how to pass a value at all!
If I change my tag to accept a string, then the value it receives if
${name} (literally). This is true even if rtexprtype is explicitly set to
true.
I can force evaluation by calling
<data:name>
<jsp:attribute name="value"><c:out value="${name}"/></jsp:attribute>
</data:name>
but that forces conversion to a String which is what I am trying to avoid...
Please can someone explain what I am missing?
Thanks/sorry,
Andrew
