Problem with population generation (reading the Configuration file ?)

[ptaillandier]

Hi,

The testLocation main (sell/example/TestLocation.java) does not work anymore. The problem comes from the population generation. The problem seems to come from the reading of the configuration file.

Log: Exception in thread "main" com.thoughtworks.xstream.converters.ConversionException: Failed calling method ---- Debugging information ---- message : Failed calling method cause-exception : java.lang.NullPointerException cause-message : null method : core.io.configuration.GosplConfigurationFile.readResolve() class : core.io.configuration.GosplConfigurationFile required-type : core.io.configuration.GosplConfigurationFile converter-type : com.thoughtworks.xstream.converters.reflection.ReflectionConverter path : /GosplConfiguration version : 1.4.9

Population generation is ok. But still have problem creating shape file in TestLocation.

In order to fix bug, you have to upload the new sample folder or generate a new configuration file, using the one in gospl

fixed (now, it is possible to save a population into a shapefile even if some entities do not have a location)

Had this bug as well. In last commit I added something on the constructor of the GoSplConfigurationFile to never have null. Was making my tests functional again, hope it makes sense ? this.keyAttribute.putAll(keyAttribute == null ? Collections.emptyMap(): keyAttribute);
