Phaser 2.0 - TilemapLayer scrollFactor collision offset error correction

[SHM]

When scrollFactor is set to != 0 the collision are affected by the offset.  

this.layer.scrollFactor = 1.2;this.game.physics.arcade.collide(this.player, this.front);

Is there a correction that can be set on  the layer?

 

Thanks
