Overlay Arrow disappears on setConnector()

[Shiva Chetan.K.S]

I used setConnector() method to change the stub value and gap value.

connection.setConnector(

['Straight',

{ stub: [leftOffsetStub, 30], gap: [0, rightOffsetGap] }

]);

But After this, the overlay Arrow disappears.

I have set overlay as below.

this.jsPlumbInstance.importDefaults({

Overlays: [

[ 'Arrow', { width: 10, length: 10, foldback: 0.3, location: 0.7 , cssClass: 'ut-arrow-class', id: 'myArrow'} ]

]

How to change the connector value of a particular connection with Overlay arrow as it is ?

Thanks in advance.

Waiting for reply.
