Hi,

if you specify a value-binding for the q:hintLabel component that does not return a String (but for example to a HashSet), you get the following exception:

java.lang.ClassCastException: java.util.HashSet cannot be cast to java.lang.String

     [...]

The HintLabelRenderer should not cast to a String, but instead call getString() on the object, just like the other JSF components.

Furthermore, if you specify a Converter to work around this bug, you get the same exception, even though the Converter#getAsString() method is called.

Can you look into this?

Thanks,

David.
