Hello Scott,
As Fintan said debugging is not available in eclihx yet. I have some
experience in integrating fdb from flex into eclipse environment but
there're still a lot of things be done to make this feature work and
work stable.
Currently eclihx can auto-complete different names after dot, like
packages, function calls, properties after "this.". There're number of
request about make auto-completion work with imported classes, local
variables, parameters and so on. The full list is available at
http://code.google.com/p/eclihx/issues/list. I'm going to improve this
situation and think this's a top-priority task for the near future.
Nikolay.
