How to display State Information to a list of participants dynamically

Question

I have tweeked the Yo- CordApp to send to a list of participants instead of single participant in the target. I would like to send the YO to more than one Party, moreover I just want to display the state information to the parties which does not require the signatures of all parties. But I am stuck with the below error:

FlowLogicRef cannot be constructed for FlowLogic of type net.corda.yo.YoFlow as could not find matching constructor for: {target=null}

This is the link to my code: https://github.com/ToniyaSundaram/CordaProjects.

Answer 1

The if condition mentioned below will never be true:
if (acceptors != null) {
    acceptors.add(to)
}

because you have set the 
val acceptors : ArrayList<Party>? = null;

So the if condition is always false and acceptors.add(to) is never executed.

Instead of 
val acceptors : ArrayList<Party>? = null;    try    val acceptors = mutableListOf<Party>()
