P2JS and Relatively Positioned Group Children

[Sunburned Goose]

Is it a known behavior of child sprites that are positioned relative to a positioned parent group have their physics and collision boundaries based on the relative positions in the game world?

var myGroup = game.add.group();myGroup.enableBody = true;myGroup.enableBodyDebug = true;myGroup.physicsBodyType = Phaser.Physics.P2JS;myGroup.x = 1700;myGroup.y = 1700;var mySprite = myGroup.create(0,0,texture);mySprite.x = 0;mySprite.y = 0;mySprite.body.static = true;mySprite.body.clearShapes();mySprite.body.setCircle(mySprite.width / 2);

When I do this, it looks like this, with the texture showing up at 1700,1700 but the boundaries are at 0,0.

 

 

 

What it should look like is this when I change the coordinates,

 

var myGroup = game.add.group();myGroup.enableBody = true;myGroup.enableBodyDebug = true;myGroup.physicsBodyType = Phaser.Physics.P2JS;myGroup.x = 0;myGroup.y = 0;var mySprite = myGroup.create(0,0,texture);mySprite.x = 1700;mySprite.y = 1700;mySprite.body.static = true;mySprite.body.clearShapes();mySprite.body.setCircle(mySprite.width / 2);

Is it a best practice to absolutely position a group or should a group always be at 0,0?
