QT3D object rotation

[b.erdemann]

Hi,

i'm testing the 3d functions and a double rotation around the x-axis and y-axis confusing me.
First i rotate the object only 90° around x-axis or only 90° around y-axis. All ok.

  ...
  Qt3DCore::QEntity m_entityaxis4 = new Qt3DCore::QEntity(sceneRoot);
 
  Qt3DRender::QMesh m_meshaxis4 = new Qt3DRender::QMesh();
  m_meshaxis4->setSource(QUrl(QStringLiteral("qrc:/3DObjekte/cordsystem.obj")));
 
  Qt3DCore::QTransform m_transaxis4 = new Qt3DCore::QTransform();
  m_transaxis4->setRotationX(90.0f);
  m_transaxis4->setRotationY(0.0f);
  m_transaxis4->setRotationZ(0.0f);
  
  m_entityaxis4->addComponent(m_meshaxis4);
  m_entityaxis4->addComponent(m_transaxis4);
  ...

Two rotations like 90° around X-Axis and 90° Z-Axis working. But i think there is a problem rotate X-Axis and Y-Axis. I take some screenshoots.
Image rotations

It looks like there is a rotation around the X-Axis but then the Y rotation is around the orginal y-Axis not around the Y-Axis after the first rotation around the x-axis!?
