Trouble Cause Solution(s)
- Trouble: NativeOperation public static org.atl.engine.vm.nativelib.ASMNumber org.atl.engine.vm.nativelib.ASMInteger.operatorMinus(org.atl.engine.vm.StackFrame,org.atl.engine.vm.nativelib.ASMInteger,org.atl.engine.vm.nativelib.ASMNumber)
Cause: You use negative integer to compare: e.g. if self.upper = -1 ...
Solutions: Use (0-x) operation: e.g. if self.upper = (0-1) ... or change your comparaison if it is possible: e.g. if self.upper < 0 ... - Trouble: ERROR: could not find operation including on Module having supertypes: [OclAny]) in a called rule
Cause: Your called rule doesn't return the good type (problably any)
Solution: Add a return type on your called rule by adding the do clause: e.g.
rule myCalledRule() {
to
out : XML!Element...
do {
out
}
}
