When adding a new MagmaCollection, I was adding an index with a wrong 
accessor name (#step instead of the correct one #stepNumber):

IFIEtayageAchievement>>initialize
	super initialize.
	etayageStepAchievements := MagmaCollection new.
	etayageStepAchievements
		addIndex: (MaIntegerIndex attribute: #stepNumber)

See the attached screen capture, it show the id in question is about 
Integer.
Looking at the debugger, in instance variable classById, integer has two 
id 107 and 214. I don't know if this normal or not.

I will investigate that.

No, it should not be that problem this time :)

Thanks,
