AppSourceCop Error AS0032

  • Artikel

Controls that have been published must not be deleted.

Description

Controls that have been published must not be deleted, because it will break dependent extensions.

Remarks

Removing a control which has been published is not allowed because it will break dependent extensions which are referencing or modifying it.

Note

Renaming a control will also trigger this error. AppSourceCop will consider the renamed control as a new control, unrelated to the one defined in the previous version.

How to fix this diagnostic?

If the control was removed, revert the change by adding back the control and mark it as Obsolete.

If the control was renamed in order to change its display string in the web client, consider using the Caption property instead.

If the control was renamed in order to comply with naming rules such as AS0011, consider obsoleting the control and introducing a new one.

Examples of errors for dependent extensions

The following examples show some of the compilation errors that will be reported on dependent extensions if a control is removed from one version to another.

Version 1.0 of the extension defines a page named MyPage that contains a control named MyControl. Version 2.0 does not define this control anymore.

Example 1 - Extensions modify this control

If a dependent extension modifies this control in a page extension or customization, when compiling against version 2.0, this will lead to a compilation error similar to The control 'MyControl' is not found in the target 'MyPage' (AL0270).

pageextension 50100 SomePageExtension extends MyPage
{
    layout
    {
        modify(MyControl)
        {
            Visible = true;
        }
    }
}

Example 2 - Extensions referencing this control as an anchor for a change

If a dependent extension uses this control as an anchor for a change in a page extension or customization, when compiling against version 2.0, this will lead to a compilation error similar to The control 'MyControl' is not found in the target 'MyPage' (AL0270).

pageextension 50100 SomePageExtension extends MyPage
{
    layout
    {
        addafter(MyControl)
        {
            field(SomeNewControl; 15)
            {
            }
        }
    }
}

Example 3 - Extensions moving this control

If a dependent extension is moving this control in a page extension or customization, when compiling against version 2.0, this will lead to a compilation error similar to The control 'MyControl' is not found in the target 'MyPage' (AL0270).

pageextension 50100 SomePageExtension extends MyPage
{
    layout
    {
        movefirst(content; MyControl)
    }
}
