The reason for this kind of problem is usually a missing rule dependency, in this case between the generator and the framework. I.e. an output tag of the rule that produces the framework must appear as some sort of input to the generator rule. For more concrete help, I'd need to see the project. If you can't share it, you might want to produce a minimal example that exhibits the problem.
