[kepler-dev] Adding new directors to the framework.

[Panickos Neophytou]

Hi all,

I'm trying to implement a new Director. When I try to insert it into a
workflow (using "Instantiate component" menu item) I get the following
exception (end of email), although the director appears in the
workflow in the end. Is there a special guide on Directors?

Also, how is it possible to add a new Actor or Director to the
sidebar? I'm using the checked-out version from SVN and all the
modules etc., and developing from Eclipse. The guide in the User
Manual says something about a context menu item of the actor called
"Save in Library..." but that does not exist in Kepler 1.x(dev).

Thanks,
Panickos
