I have 3 emadl files containing:

component Add{
	ports	
in Q num1,
in Q num2,
out Q erg;

implementation Math{
erg = num1 + num2;
}
	
}

component Add1{

	ports 

	in Q testin,
	out Q testout;

instance Add add;

connect testin -> add.num1;
connect testin -> add.num2;
connect add.erg -> testout;

}

component Add2{

	ports 

	in Q test1,
	out Q test2;

instance Add1 adder;

connect test1 -> adder.testin;
connect adder.testout -> test2;

}

Building Add and Add1 works just fine, but as soon as I try to build Add2 I get following Error-message:

[WARN]  name of connector's source/target does has two parts: instance.port, cannot resolve port

Changing variablenames etc. does not work either. For building I am using version 0.4.3 of the generator
