[kepler-dev] GARP actor issues

[R.P.Mciver at cs.cardiff.ac.uk]

Hi all,

Hopefully someone can help me out here, I've playing about with the  
kepler UI (mainly just looking at how things work etc.) and thought  
I'd try using my slightly modified GUI to compose some workflows  
utilisng the GARP set of actors, similar to the niche modelling  
examples that come with kepler.

Unfortunately I've been getting some errors (well, stack overflows to  
be precise). After spending a long time thinking it was as a result of  
something I'd changed in the UI, I went back and tried the same on a  
clean install of the 1.0.0 release, only to find there were still some  
problems.

It seems that whenever I provide the GARPPresampleLayers actor with a  
"layerset" input file which is located anywhere other than the  
"$Kepler/lib/testdata/garp" folder then kepler crashes out with a  
stack overflow.

The only difference in the error between using "vanilla" kepler 1.0.0  
and my modified version is that when attempting to execute the actor  
in my code I get the stack overflow regardless of where the layerset  
file is located.

Any ideas what is going on here - is the location for where the file  
has to be defined somewhere? I've tried just executing the  
GARPPresampleLayers actor in isolation so I'm fairly certain it's not  
a problem with some other part of a workflow.

Any help would be appreciated!

Cheers,

Russell
