I've logged an issue for this:<BR>
<A HREF="https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=1360">https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=1360</A><BR>
<BR>
<BR>
When baseClass is:<BR>
class com.sun.faces.el.CompositeComponentAttributesELResolver$ExpressionEvalMap<BR>
<BR>
BeanValidator.isResolvable(...) returns false because ExpressionEvalMap is a Map -- and never attempts to traverse the composite component.<BR>
<BR>
This is a big problem with Bean Validation support, since probably the most attractive feature of JSF2 is composite components, and this means BeanValidation will not function at all within any composite components.<BR>
<BR>
// case 1, base classes of Map, List, or Array are not resolvable<BR>
if (null != <B>baseClass</B>) {<BR>
if (<B>Map.class.isAssignableFrom(baseClass)</B> ||<BR>
Collection.class.isAssignableFrom(baseClass) ||<BR>
Array.class.isAssignableFrom(baseClass)) {<BR>
failureMessage = "<B>Unable to validate expression " + valueExpression.getExpressionString() +</B><BR>
<B> " using Bean Validation. Expression evaluates to a Map, List or array.";</B><BR>
result = false;<BR>
}<BR>
}<BR>
<BR>
<BR>
<B>This can be reproduced by using the following component, and an Object annotated with JSR303 annos.</B><BR>
Consuming page: (I've also tried "value" as the for="..." attribute value with no success)<BR>
