Re: [Repast-interest] Booleans in parameter files

[Jason M. <ni...@ya...>]

I'm having a problem with Booleans as well. 

When I use the wizard, I try specifying words for the
values of my booleans: "true", "false". But then the
model keeps throwing exceptions complaining that it
wants numeric values. So I go into the xml file & set
numeric values ("0" and "1"). Then when I try to run
it, the model caves and repast.log declares that I
should be using "true" and "false". 

Would someone who's had success with booleans post a
snipped of their .xml parameter file please?

Thanks,

Jason
