[Repast-developer] IllegalArgumentException: max <= min

[pchacin <pc...@ac...>]

Greetings

I'm experiencing a very frustrating problem when creating a Histogram in
RepastJ 3.0. From time to time, I get this exception:
Exception in thread "Thread-4" java.lang.IllegalArgumentException: max <=
min
	at hep.aida.ref.FixedAxis.<init>(Unknown Source)
	at hep.aida.ref.Histogram1D.<init>(Unknown Source)
	at
uchicago.src.sim.analysis.HistogramItem.getBinValues(HistogramItem.java:215)
	at
uchicago.src.sim.analysis.OpenHistogramStat.record(OpenHistogramStat.java:190)
	at uchicago.src.sim.analysis.OpenHistogram.step(OpenHistogram.java:293)
	at simrealms.views.histograms.HistogramView.refresh(HistogramView.java:98)

The way I'm creating the histogram is hard to show because I created a
simulation framework that wraps the Repast classses. However, I'm pretty
sure that the values in the histogram are in the range 0.0 1.0. and I
created it with these values as lower and upper bound, respectly. 

However, in some circunstances the max and minimum could be the same (both 0
or both 1) and therefore the condition max <= min could become true. 

If this is the reason, I found this behavor annoying, because there is no 
reason why the histogram could have a 100% of items  with the same value.

I'll appreciate any help regarding this issue. Thanks is advance.

Pablo
