Repeater - QQuickItem::stackAfter: Cannot stack after 0x2eb4d768 which must be a sibling

Prochy

Hi,

I'm trying set dynamic parent of item in a Repeater:

Repeater{
            model: options
            delegate: Text{
                enabled: model.modelData.enabled
                text: index+1
                anchors.fill:parent
                color: (model.modelData.enabled)?Colors.GREY:Colors.DARK_GREY
                visible: model.modelData.visible
                Component.onCompleted: {
                    var temp = findObject(sectionF, "f"+(index+1));////return right parent object
                    if(temp!=undefined)
                          this.parent = temp; 
                }
            }
        }

But the code is throwing a warning: "QQuickItem::stackAfter: Cannot stack after 0x2eaa2560, which must be a sibling".
The program is running good but I don't know where I'm doing a mistake that I'm getting this warning.
Or is it not a right solution of my problem?

Thank you for help
