Thanks for the quick reply I often end up using $CLASSPATH, which looks in the classpath for the resource.
I type in the $CLASSPATH and this is what is return " xxxxxxCLASSPATHxxxxxx " is there a way to set the classpath ? For a CompositeActor, you would probably need to edit the MoML by hand and add a Parameter: How do you edit the MoML of a composite actor by hand ? I right click and try all the options but did not get any options that allow me to edit the MoML thanks ckw I typed in the $CLASSPATH and I only get this On Tue, Oct 25, 2011 at 12:46 AM, Christopher Brooks <[email protected]>wrote: > Hi Kianwee, > My comments are interspersed with your text below. > > > On 10/24/11 8:39 AM, Edward A.
