I am trying to override a method in the Self Service Portal installed as MUI.  The error states that my signature doesn’t match the one I am overriding.  Looks correct to me...

	public class ICSInventoryLineMaint : PXGraphExtension<SPInventoryItemMaint>
	{
		public static bool IsActive() => true;

		public delegate IEnumerable FetchItemsDelegate(FetchItemsSource source = FetchItemsSource.Catalog,
			bool readOnly = false);
		[PXOverride]
		public IEnumerable FetchItems(FetchItemsSource source = FetchItemsSource.Catalog,
			bool readOnly = false, FetchItemsDelegate base_FetchItems = null)
		{

Here is a screen shot showing the squiggle

The original method signature is:

public virtual IEnumerable FetchItems(
	FetchItemsSource source = FetchItemsSource.Catalog,
	bool readOnly = false)
{

I set my delegate as optional as this is a necessary thing to do when there is an optional parameter in the original signature.

It looks like my signature matches the original.

Any idea what I have done wrong?

    I think you want:

    public IEnumerable FetchItems(
        FetchItemsSource source, 
        bool readOnly, 
        FetchItemsDelegate base_FetchItems) 
    {
         // Execute the base method
        return base_FetchItems(source, readOnly);
    }

    Leave out the = false since your delegate is going to pass a value, it will never be optional. The = null for base_FetchItems isn’t necessary since it always has a value.

    Also, and unrelated, what kind of hotkey madness is this:

    Can you try with virtual? You’re missing that.
