Why is my hyperlink / button in the grid to launch a screen disabled? - acumatica

Question

I have a customization to the Sales Orders screen, where I've added a user field (non-bound / [PXString] to hold the value of a PO Receipt Nbr. I populate it with the RowSelected event, and I'm trying to launch the Purchase Receipts screen from that field with a PXAction tied to that field's Linked Command:
The Field:
public abstract class usrPOReceiptNbr : BqlString.Field<usrPOReceiptNbr> { }
[PXString(15, IsUnicode = true)]
[PXUIField(DisplayName = "PO Receipt Nbr", Enabled = true)]
public virtual string UsrPOReceiptNbr { get; set; }
The RowSelected event code to populate the field:
var soordershipment = e.Row as SOOrderShipment;
using (new PXConnectionScope())
{
//get the extension
var soordershipmentext = PXCache<SOOrderShipment>.GetExtension<SOOrderShipmentExt>(soordershipment);
//Get the soorder cache...
SOOrder soorder = Base.Document.Current;
if (soorder != null)
{
//Now get the POReceiptLine record:
PXResultset<POReceiptLine> res = PXSelectJoin<POReceiptLine,
InnerJoin<SOOrder,
On<SOOrder.orderNbr, Equal<POReceiptLine.sOOrderNbr>,
And<SOOrder.orderType, Equal<POReceiptLine.sOOrderType>>>>,
Where<SOOrder.orderNbr, Equal<Required<SOOrder.orderNbr>>>,
OrderBy<Desc<POReceiptLine.receiptNbr>>>.Select(Base, soorder.OrderNbr);
foreach (PXResult<POReceiptLine> rec in res)
{
POReceiptLine porl = (POReceiptLine)rec;
soordershipmentext.UsrPOReceiptNbr = porl.ReceiptNbr;
break; //Stop after the first record, since I only want the highest sorted field
}
}
}
The code to launch the Purchase Receipts screen is as follows:
public PXAction<SOOrder> LaunchPurchaseReceipts;
[PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "Launch Purchase Receipts", Enabled = true)]
protected virtual IEnumerable launchPurchaseReceipts(PXAdapter adapter)
{
var soorder = (SOOrder)Base.Document.Current;
POReceiptEntry graph = PXGraph.CreateInstance<POReceiptEntry>();
var soordershipment = (SOOrderShipment)Base.shipmentlist.Current;
var soordershipmentext = PXCache<SOOrderShipment>.GetExtension<SOOrderShipmentExt>(soordershipment);
graph.Document.Current = graph.Document.Search<POReceipt.receiptNbr, POReceipt.receiptType>(soordershipmentext.UsrPOReceiptNbr, soordershipment.ShipmentType);
throw new PXRedirectRequiredException(graph, "Purchase Receipts")
{
Mode = PXBaseRedirectException.WindowMode.NewWindow
};
}
The problem is that I continue to get this error when launching the hyperlink on the PO Receipt Nbr field for that screen (it never even gets to the code to launch the screen):
...and here's the error...
I've tried forcing the field to enabled with the RowSelected event, using:
PXUIFieldAttribute.SetEnabled<SOOrderShipmentExt.usrPOReceiptNbr>(e.Cache, null, true);
But that doesn't do anything.
Any ideas?

This issue has been resolved with a suggestion from Brendan (thanks much) by using the RowSelected event to set the method's enabled property to true:
LaunchPurchaseReceipts.SetEnabled(true);
