Hi!
I had no answer on the help post, so i'm putting this here, just in case this actually is a bug.
I made a little project to pinpoint the bug (which i think it is).
It's a basic statebasedgame with two state. First one has a big abstractcomponent which triggers the start of the second one, the second one only capturing mouse events.
The first state has a component covering almost all the space. When you click on the second state, bam! The component on the first state actually catches it, and it never goes onto the second one (where there is actually no component rendered).
I've attached the source code in a zip, and here it is in this message :
TestApp.javaCode:

return _thisInstance;
}
public static final int MENUSTATE = 1;
public static final int MAINSTATE = 2;
public TestApp(String name) {
super(name);
_thisInstance = this;
this.addState(new MenuState());
this.addState(new MainState());
this.enterState(MENUSTATE);
}

Can you confirm that it is actually a bug or pinpoint what is wrong about this code?
Thanks!

They fetch the input data directly from the game container and don't care at all if they are linked to a game state or not.
