Launch "Abstract Experiment with Parameters.gaml" throws an Exception

[benoitgaudou]

When I run the Abstract Experiment with Parameters.gaml experiment, I get the following exception:

2 occurrences in 2 agents at cycle 0: Java error: nil value detected
in file<int, geometry> shp_boundary <- file_exists(dataset + 'boundary.shp') ? file<int, geometry>(dataset + 'boundary.shp') : nil ;
NullPointerException: null

msi.gaml.expressions.BinaryOperator._value(BinaryOperator.java:75)
when applying the file_exists operator on ../../Datasets/Ben Tre/boundary.shp
in initializing attribute shp_boundary
in agents Simulation 0, With parameters0

Note that this is first due to the fact that all the paths are defined for experiments located in a folder in the Experiment folder, whereas Abstract Experiment with Parameters.gaml is directly located in the Experiment folder.

In addition we can also question the file_exists operator as it returns an exception in the case where the path to the folder in which could be located the file does not exist.

@benoitgaudou the error have been removed, when dealing with #21. However, there is a Wrong Magic Number error now @ptaillandier !!!
