Hi Doru. I have updated FuelMooseExtension to work with the latest stable version of Fuel 1.8. I think this is worth it because:

1) Right now you are using an old version of Fuel (1.6) which is like an year ago. The older it is the more difficult it will be in the future to update.
2) If you don't take into account the time to compute attributes we can have improvement up to 30% in export time.
3) Fuel 1.8 is integrated by default in Pharo 2.0 now, meaning that you will have problems when moving Moose to Pharo 2.0 (because you would need 1.6).

Of course the bad news is that if you have already exported files you won't be able to import them with this new version.

If you agree, let me know. I will create a new version 1.5 in ConfigurationOfFuelMooseExtension but I don't know how the Moose image is built (it seems it is not using ConfigurationOfFuel).

Cheers
