How to execute code when my extension is uninstalled

(0) ShareShare

Posted on by Severin S 5

Hello,

In BC20 I'm trying to execute code before my extension gets uninstalled. Is there a way to do this?

I can't seem to find a trigger which executes at this event.

    Hi,

    You can subscribe the Page "Extension Details" 'OnAfterActionEvent', 'Uninstall' action as shown below screenshot.

    Hi,

    Thank you for the response.

    The OnAfterActionEvent didn't work, but the the OnBeforeActionEvent worked.

    I can use this to trigger my code.

    The problem with this way of triggering my code is, that I have no way to check if the uninstalled App/Extension is mine.

    If I use the "Published Application"-Parameter I get an error: "The application object or method 'Published Application' has scope 'OnPrem' and cannot be used for 'Extension' development".

    I can't switch my Environment to an OnPrem-Environment.

    Do you know any other way how I can check if the uninstalled app is my app?

    Hi,

    Have you tried using the 'Nav App Installed App' record type?

    Code below:

    codeunit 90137 ExtensionDetails
{
    [EventSubscriber(ObjectType::Page, Page::"Extension Details", 'OnBeforeActionEvent', 'Uninstall', true, true)]
    local procedure MyProcedure()
    var
        NavApp: record "NAV App Installed App";

    begin
        if NavApp.Name = 'My App' then begin
            //[DO STUFF]
        end;
    end;
}
