AppSourceCop Error AS0033

  • Article

Views that have been published must not be deleted.

Description

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

Remarks

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

Note

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

How to fix this diagnostic?

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

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

If the view was renamed in order to comply with naming rules such as AS0011, consider obsoleting the view 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 view is removed from one version to another.

Version 1.0 of the extension defines a list page named MyListPage that contains a view named MyView. Version 2.0 does not define this view anymore.

Example 1 - Extensions modify this view

If a dependent extension modifies this view in a page extension or customization, when compiling against version 2.0, this will lead to a compilation error similar to The view 'MyView' is not found in the target 'MyListPage' (AL0533).

pageextension 50100 SomePageExtension extends MyListPage
{
    views
    {
        modify(MyView)
        {
            Visible = true;
        }
    }
}

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

If a dependent extension uses this view 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 view 'MyView' is not found in the target 'MyListPage' (AL0533).

pageextension 50100 SomePageExtension extends MyListPage
{
    views
    {
        addafter(MyView)
        {
            view(SomeNewView)
            {
            }
        }
    }
}

Example 3 - Extensions moving this view

If a dependent extension is moving this view in a page extension or customization, when compiling against version 2.0, this will lead to a compilation error similar to The view 'MyView' is not found in the target 'MyListPage' (AL0533).

pageextension 50100 SomePageExtension extends MyListPage
{
    views
    {
        movefirst(MyView)
    }
}
