It seems to me that this component is broken. When I try to test this my
browser complains about javascript errors and the child list stays
empty. I don't know whats wrong with it and I'm too lazy to debug it.
You should contact the author of the component to get a fix.

I'm guessing I have some strange configuration, since I know this code
works elsewhere. Here's how I specify the library in my .application file:
<library id="man"
specification-path="classpath:/man/library/ManSH.library"/>

Please give us the exact error message (doesn't need to be the whole
stack trace but a few more lines from which we can see at which point
the exception is thrown would be helpful...).

Thanks for the quick response. The source is exactly as here except I
changed the package names:
http://lombok.demon.co.uk/tapestry4Demo/pages/dynamicSelectionList/TestDSLComponent2Source.html
The error occurs on line 7 of TestDSLComponent2.page:
<page-specification
class="gov.nmcourts.caselookup.pages.TestDSLComponent2">
Thanks,
Jacob
