Finding a unitdef metal cost in an *A mod [solved]

[Bla]

in the spring java wrapper thing, given UnitDef uni and EngineCallback cb, to find the cost in metal I do
uni.findCost(cb.getResourceByName("metal"))
but I keep getting NullPointerException.

Is the resource name not "metal"?

[gajop]

try "Metal" instead

Hey, works thanks!
