I'm trying EAP MPS with Tutorial (I know, quite crazy idea), and I got stuck early after start with my Generator. After I changed CalculatorImpl into property macro (with node.name in the inspector) class itself seems fine (no red errors), but after hitting Preview Generated Text on my Calculator from the sandbox, following errors occur:
-- was input: [root] Calculator "MyCalc" in sk.naive.mps.test.calculator.sandbox@1_0
-- was template: [root] ClassConcept "CalculatorImpl" in sk.naive.mps.test.calculator.generator.template.main@generator
-- was rule: [_$attribute] PropertyMacro <no name> in sk.naive.mps.test.calculator.generator.template.main@generator
What exactly is wrong here? What should I do otherwise?
