[Spoon-discuss] code creation using factories

[Jakub Mikulski]

Thanks for your reply, but there still is a problem. The line:

f.Field().createReference("java.lang.System.out");

creates a CtFieldReference, while the first argument to createInvocation 
needs to be a CtExpression - how do I fix that? I've been trying 
something like this:

CtFieldReference<?> streamRef = 
f.Field().createReference("java.lang.System.out");
CtExpression<?> itarget = f.Code().createVariableAccess(streamRef, true);

Unfortunately, it doesn't work... Any help would be appreciated.

Regards,
km
