when i use <s:enumConverter /> to convert string back to enum type, the appserver throwed a null pointer exception said that the converter can not determine the enumType. i found the ValueBinding's getType() method return null value , so we can not get the correct enum type from the faces context in jsf 1.1, is it right?
I have not looked at that specific tag on websphere. Can you verify that the same application works as expected on Jboss?
Also you could post some more information on the application and error.
