On moving the nodes, the label text of the "LineConnector" connecting two node becomes upside down. That is on moving one of the two node to the opposite side of the other node from its current position in x direction will make the text to be drawn upside down. To avoid this a workaround has been created in which the label class is customized and a property called rotate is included in it which when set to true rotates the drawing of text by 180 degree.
