fail to run headless

[meta00]

With this model:
Lotka-Volterra (Influence of Integration Step).gaml.zip

maths.xml.zip

Do you know why?

@gnoubi and @benoitgaudou @jdzucker

So far, all of the models in Toy Models and Tutorials were tested (load and run). We found a number of models that headless failed to run with the above-mentioned errors. Including (in the latest gama version - official):
Toy Models/Predator Prey/Lotka-Volterra (Influence of Integration Step).gaml
Toy Models/Flood Simulation/models/Hydrological Model.gaml
Toy Models/Life/Life.gaml
Tutorials/Road Traffic/models/*.gaml

Can you please check and let us know asap before the first release at the beginning of June?

After some checks on the Life.gaml model, this issue comes from the fact that the model has some parameters of type color (rgb), and more precisely from the fact that GAMA has a wrong serialization of this type of objects.

If you look at the XML file generated, the value for these attribute is something like color[white], a string that GAMA is not able to transform into a genuine GAMA color object.

An issue will be posted on the GAMA list.
