Using a list attribute with a item that contains an expression causes an
exception to be produced.
Consider the following definition:
<definition name="customers/info" extends="customers/base">
<put-list-attribute name="testList">
<add-attribute expression="${customer.id}" />
</put-list-attribute>
</definition>
This produces the attached exception. If I add `value="xxxx" ` to the
add-attribute (and keep expression=) no exception is produced but the attribute
takes on the value, not the expression.
This same add-attribute works fine as a `put-attribute` on the definition
outside of the list. Note that the exception is thrown at the time the
attribute is requested to be rendered, eg:
<c:forEach var="item" items="${testList}">
<li>${item}</li> <%-- HERE --%>
</c:forEach>
