[kepler-users] Kepler, adding composite actors?

[Wibke Sudholt]

Hi,

Regarding adding composite and MoML class actors in the actor tree, I put in
a bug in the Kepler bug tracker a while ago, but to my knowledge it is not
fixed yet. See:

http://bugzilla.ecoinformatics.org/show_bug.cgi?id=1851

You can observe the problem when you try some of our actors from the
Resurgence project under Domain Specific/Computational Chemistry (some
actors appear after printing an error, some hang up the Kepler interface).

Any hints are very welcome!

Good to know that I am not the only one who would like to have this working
:-)

Best regards,

Wibke
