Re: event framework question

Hi Patrick,

thanks a lot - now it works. As a follow up I have another question:
I want to parameterize 

foo LAZY HOST host1.cern.ch:receive:start;

I.e. I have a "base component" which looks like

installEnv extends {

serverName "host10.cern.ch";
serverProcessName "server";
}

It gets included into the prevevious (below) mentionend components. Thus 
on the sender component I'd like to do something like:

sendTo:foo LAZY HOST 
(installEnv:serverName):(installEnv:serverProcessName):start;

This doesn't work... What would be the right syntax to do something like 
that ?

Thanks again,
Andreas
