[XCore] derived feature unimplemented [message #1022244]

Hi,

another problem with (the newest M6 milestone of) XCore. There are two xcore projects named 'base' and 'extender'. The 'base' project is generated from base.xcore:

package base

class Foo {}

class Bar {
	int x
	int y
	
	derived int sum get {
		return x + y
	}
}

class MyClass extends Foo, Bar {}

the 'extender' depends on 'base' and is genreated from extender.xcore:

package extender

import base.Foo
import base.Bar

class MyClass extends Foo, Bar {}

The result is that base.MyClassImpl is different than extender.MyClassImpl. The getSum() method from base.MyClassImpl is generated correctly. The same method in extender.MyClassImpl throws UnsupportedOperationException. Is it a bug or did I miss something? Both projects are attached in the ZIP file.

Martin,

That definitely sounds like a bug so given it's reproducible in M6---I
haven't the time to try because I'm preparing for EclipseCon---please
open a bugzilla. Of course you can change the order of the inheritance,
but your in real life code that might not be okay.
