How to X rotate object using other object as reference?

Maybe I am having the same issue from here

Problem with getLocalRotation().FromAngleAxis()

Yes, I updated the javadoc to note that: [java] /** * toAngles returns this quaternion converted to Euler * rotation angles (yaw,roll,pitch). * Note that the result is not always 100% accurate due to the implications of euler angles. * @see http://www.euclideanspace.com/maths/geometry/rotations/conversions/quaternionToEuler/index.htm * * @param angles * the float[] in which the angles should be stored, or null if * you want a new float[] to be created * @retur…

I did notice that:
Getting the x angle allways works as intend using this method.
Getting the y angle works, but get in the matrix dirt from x rotation and z rotation.
Getting the z angle dont work at all, it seens to get dirt, and also rotate only to 180º , then invert the diretion somehow.

I was planning to make a video, if someone that understand rotation and is willing to help, I could post this video ilustrating this, but you can also test this code and :

1. presss q+space for a while will rotate on x, cube x get the x rotation allways, other cubes stays in the same position as expected.
2. press a+space for a while will rotate on y, you will notice that all cubes moves not only the y one as expected.
3. press z+space for a while will show something that I really dont get it
