Could you share your extended page? Either the project XML or the complete page as shown in the “View ASPX” command would work.

This is my original page, but I tried simply adding a basic popup dialog panel element and the result is the same.

Yeah, it is strange ¿what is the name of your element?

cstCopyOpportunityDialog

I believe this script shows the map:

It looks like once we add the panel to the screen, the JavaScript code for the map is not loading anymore.

I suspected as much, but couldn't find hard evidence. Any idea why or how to fix it?

I think I figured out the problem. I’m not sure how @MarcoL45 discovered that this goes missing from the page, but he’s right.

<% PX.Objects.CS.PXAddressLookup.RegisterClientScript(this, ds.DataGraph); %>

And attempting to include it in the ASPX page doesn’t work because it’s removed by the validation process. Since the AddressLookupPanel.inc is added as an include, it stands to reason that when modifications are made to the ASPX page, the validations removes it there as well. That’s the best I can come up with.

This code determines if Bing or Google maps API should be used, which leaves it out of the page, as @Zoltan Febert figured out. All we need to do is get this to run. In order to do that, I added it into a Page_Load event in the code-behind file CR304000.aspx.cs and replaced the original file. This works!

However, I’m not sure this is actually a great solution, since it’s really not a customization layer anymore, but rather a replacement.

I also attempted to include this with a PXLiteral, but either I did it wrong or it doesn’t work.

@darylbowman I think everything is a great solution when we need to fix real Acumatica bugs.

I snagged this from this answer:

public OpportunityMaint_Extension : PXGraphExtension<OpportunityMaint>
{
    public override void Initialize()
    {
        base.Initialize();

        // Add the Page_Load event handler
        var page = System.Web.HttpContext.Current?.Handler as PX.Web.UI.PXPage;
        if (page is object)
            page.Load += Page_Load;
    }

    // Executes the PXAddressLookup script which is broken by the page customization
    private void Page_Load(object sender, EventArgs e)
    {
        var page = (PX.Web.UI.PXPage)sender;
        PX.Objects.CS.PXAddressLookup.RegisterClientScript(page, Base);
    }
}

This works well and seems like a great solution.

Great work @darylbowman
