Can you tell me, which graph you’ve extended, which event? Or it was customization plugin extension?

The actual content of the page doesn’t matter. You can create a new ‘Code’ page and paste only that line in and it will break.

I tried to find class ApplyDocuments in Acumatica source code, but failed. I’m on the build 22.206.0035 . The code, which I’ve written goes below:

namespace PX.Objects.SO
{
  public class SOOrderEntry_Extension : PXGraphExtension<PX.Objects.SO.SOOrderEntry>
  {
    #region Event Handlers

    public virtual void _(Events.RowUpdated<SOOrder> e)
        {
            var amountOfPrepayments = 123;
            ApplyDocuments.SetCaption($"Apply Prepayment of ${amountOfPrepayments}");
        }

    #endregion
  }
}

any idea what I’m missing?

ApplyDocuments is a custom action I defined on the ARInvoiceEntry graph, but I don't think that had any impact on the issue. I was on an earlier build, but I don't know which one at the moment. Maybe it was fixed in a later build?

Without seeing actual source code, I can only guess. 

Hi All,

I have encountered a similar bug (23R1). It’s a very simple change to a FieldSelected event, but using GetExtension<>() for an inventory item extension causes the code editor to show only one word of text “Cancel” in the top right corner.

This seems to be the line of code that causes the issue:
var itemExt = item.GetExtension<PX.Objects.IN.InventoryItemExt>();

“item” is just a row of the InventoryItem table (result of a DAC query).

The code itself compiles, and I am able to alter the event handlers as I like, but I must do so directly from the .cs file in App_RuntimeCode. 

I have never had this problem with any other custom extension… Happy to share more code if you are curious!
