I'm not removing the component either. Could it be an issue that the parents in my case is a qx.ui.pageview.tabview.Page and the component i'm moving is a qx.ui.layout.CanvasLayout ? The error seems to suggest that it might be related to layout effects.

But i could be mistaken ;-) This works for me, though: =======example code=============== var superParent = new qx.ui.layout.VerticalBoxLayout(); superParent.set({ top: 0, left: 0, bottom: 0, right: 0 }); superParent.addToDocument(); var parentX = new qx.ui.layout.Canvas(); parentX.set({heigth: "50%", width: "100%"}); var parentY = new qx.ui.layout.Canvas(); parentY.set({heigth: "50%", width: "100%"}); superParent.add( parentX, parentY ); var button = new qx.ui.form.Button('Click me to move me down'); button.addEventListener('execute',function(){ parentY.add(button); }, this); parentX.add(button); ===================================== When you click the button, the button is removed from parentX and added to parentY. Note, that i do not _remove_ the button. I just add it to parentY. If you remove the button, i think it gets destroyed! Which would explain the error message you have received.
