Hi Mark, Complex parameters are not supported by the designer and they probably never will. We have already made nodes pluggable, so that you can provide your own configuration form for a custom node, and will probably do this for actions as well in the future. But supporting these complex variables in a generic way is close to impossible imo. Regards, Koen Btw. 3.1.0.beta2 was build and tested on Eclipse 3.3.
