Yes, it works. Thanks a ton.
I have another DirectLink component in the spec. But I just can't seem
to link it to the page containing the component. The exception report
indicates that it can't find the listener in the component. I know it
is not there because that's not what I want it to be; it should go and
look for the listener created in the page that called the component.
Would you show me how to do it again?
