Hi All,
I'm getting the following exception when I add a class attribute to s:link
java.lang.IllegalArgumentException: Component property class is not writable

If I remove the class attribute from the s:link then all is well, so clearly this is
causing the problem.
Can s:link be modified to allow use of the class attribute? Or is there a good reason for
it not being allowed?
Regards,
Chris.
