Workflow Event Handler Errors

Question

Hello guys,

I am having an issue with a workflow event handler:

Workflow declaration:

.WithHandlers(handlers =>
{
    handlers.Add(handler => handler
        .WithTargetOf<ARBalances>()
        .OfEntityEvent<ARBalancesCreditHoldExt.MyEvents>(e => e.CreditLimitViolated)
        .Is<SOShipmentEntryCreditHoldExt>(g=> g.OnCreditLimitViolated)
        .UsesPrimaryEntityGetter<
            SelectFrom<SOShipment>.
            Where<SOShipment.customerID.IsEqual<ARBalances.customerID.FromCurrent>>>()
    );
    handlers.Add(handler => handler
        .WithTargetOf<ARBalances>()
        .OfEntityEvent<ARBalancesCreditHoldExt.MyEvents>(e => e.CreditLimitSatisfied)
        .Is<SOShipmentEntryCreditHoldExt>(g => g.OnCreditLimitSatisfied)
        .UsesPrimaryEntityGetter<
            SelectFrom<SOShipment>.
            Where<SOShipment.customerID.IsEqual<ARBalances.customerID.FromCurrent>>>()
    );
})

//Add to State
lowStates.Update<SOShipmentStatus.open>(flowState =>
                            {
                                return flowState
                                .WithActions(actions=> 
                                actions.Add(productionConfirm, c=>
                                c.WithConnotation(ActionConnotation.Secondary)))
                                .WithEventHandlers(handlers=>
                                {
                                    handlers.Add<SOShipmentEntryCreditHoldExt>(g => 
                                        g.OnCreditLimitSatisfied); //CS0029 - 
//Error (active)	CS0029	Cannot implicitly convert type //'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment, //PX.Objects.AR.ARBalances>' to //'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment>'			

                                    handlers.Add<SOShipmentEntryCreditHoldExt>(g=> 
                                        g.OnCreditLimitViolated); //CS0029 - 
//Error (active)	CS0029	Cannot implicitly convert type //'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment, //PX.Objects.AR.ARBalances>' to //'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment>'
                                });
                            });
//Graph PXWorkflowEventHandler
 public class SOShipmentEntryCreditHoldExt : PXGraphExtension<SOShipmentEntry>
 { 
// other logic

      public PXWorkflowEventHandler<SOShipment, ARBalances> OnCreditLimitViolated;
      public PXWorkflowEventHandler<SOShipment, ARBalances> OnCreditLimitSatisfied;
 }

//DAC Workflow Event
public class ARBalancesCreditHoldExt : PXCacheExtension<ARBalances>
{
    public class MyEvents : PXEntityEvent<ARBalances>.Container<MyEvents>
    {
        public PXEntityEvent<ARBalances> CreditLimitViolated;
        public PXEntityEvent<ARBalances> CreditLimitSatisfied;
    }
}

If I change the PXWorkflowEventHandler to just

public PXWorkflowEventHandler<SOShipment> OnCreditLimitViolated; public PXWorkflowEventHandler<SOShipment> OnCreditLimitSatisfied;

The .WithHandlers declaration of the handler throws this error:

Severity Code Description Project File Line Suppression State Details
Error (active) CS0029 Cannot implicitly convert type 'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment>' to 'PX.Data.WorkflowAPI.PXWorkflowEventHandler<PX.Objects.SO.SOShipment, PX.Objects.AR.ARBalances>' NCRLog C:\Acumatica ERP\Acu\App_Data\Projects\NCRLog\NCRLog\Workflow\SOShipmentEntry_WorkflowExt.cs 210

I can tell i am doing something fundamentally wrong, but I have no clue what it could be, could anyone offer some help?

Not too sure if this is right, but I changed extended the SOShipment DAC to contain the MyEvents class as follows:

 public class SOShipmentCreditHold : PXCacheExtension<SOShipment>
 {
		public class MyEvents : PXEntityEvent<SOShipment>.Container<MyEvents>
		{
public PXEntityEvent<SOShipment> CreditLimitViolated;
public PXEntityEvent<SOShipment> CreditLimitSatisfied;
		}

	}

and updated my workflow event declaration as follows:

.WithHandlers(handlers =>
{
    handlers.Add(handler => handler
        .WithTargetOf<SOShipment>()
        .OfEntityEvent<SOShipmentCreditHold.MyEvents>(e => e.CreditLimitViolated)
        .Is<SOShipmentEntryCreditHoldExt>(g=> g.OnCreditLimitViolated)
        .UsesPrimaryEntityGetter<
            SelectFrom<SOShipment>>()
    );
    handlers.Add(handler => handler
        .WithTargetOf<SOShipment>()
        .OfEntityEvent<SOShipmentCreditHold.MyEvents>(e => e.CreditLimitSatisfied)
        .Is<SOShipmentEntryCreditHoldExt>(g => g.OnCreditLimitSatisfied)
        .UsesPrimaryEntityGetter<
            SelectFrom<SOShipment>>()
    );
})

This is my PXWorkflowEventHandler in the graph:

public class SOShipmentEntryCreditHoldExt : PXGraphExtension<SOShipmentEntry>
 { 
// other logic

      public PXWorkflowEventHandler<SOShipment, ARBalances> OnCreditLimitViolated;
      public PXWorkflowEventHandler<SOShipment, ARBalances> OnCreditLimitSatisfied;
 }

This fires as I expect them too.
