QT3D object rotation

Hi,
i'm testing the 3d functions and a double rotation around the xaxis and yaxis confusing me.
First i rotate the object only 90° around xaxis or only 90° around yaxis. 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 XAxis and 90° ZAxis working. But i think there is a problem rotate XAxis and YAxis. I take some screenshoots.
Image rotationsIt looks like there is a rotation around the XAxis but then the Y rotation is around the orginal yAxis not around the YAxis after the first rotation around the xaxis!?
