Using multiple namespaces for the same pageextension

[gntpet]

1. Describe the bug Project, with multiple namespaces for the same object, does not compile, but gives the following error:

The extension object 'CustomerListExt2' cannot be declared. Another extension for target 'Customer List' or the target itself is already declared in this module. 2. To Reproduce Create new AL project with two files

namespace DefaultPublisher.myNameSpace1;

using Microsoft.Sales.Customer;

pageextension 50100 CustomerListExt1 extends "Customer List"
{
    trigger OnOpenPage();
    begin
        Message('App published: Hello world1');
    end;
}

namespace DefaultPublisher.myNameSpace2;

using Microsoft.Sales.Customer;

pageextension 50101 CustomerListExt2 extends "Customer List"
{
    trigger OnOpenPage();
    begin
        Message('App published: Hello world2');
    end;
}

3. Expected behavior I expect that project compiles successfully, and I can have multiple pageextensions (or any other extension type), for the same project.

According to namespace documentation, it should be possible. My objects are named differently

5. Versions:

• AL Language: v12.3.900902
• Visual Studio Code: 1.84.2

This is by design, a pattern we have had from the beginning and does not change with namespaces

It is a topic we continue to think about.

Just to be sure: Esben wrote yesterday on Yammer/Viva Engage that this feature is being worked on for the next major. I hope you are not working against each other 😛
