Currently, no expression ID information is available in modules that
have been called with xdmp:invoke(). Without an expression ID we
can't set a breakpoint. I'm working with MarkLogic to see if there is
a workaround or a fix to get this information in invoked modules.
Version 1.0.2 includes a couple of updates that may help. There is
better support for displaying MarkLogic source from the <installdir>/
Modules/MarkLogic directory and when no breakpoint information is
available the breakpoint column shows an mdash instead of the BP
insert icon. Hopefully this will help people understand there isn't
information available instead of leading them to think they can set a
BP when they can't.
