Fiori Elements Object Page: Placing actions before standard action Delete

[a_oezsoy]

Hi,

I have a Fiori Elements app and I am having difficulty placing my action button before the standard Delete action in the object page.

I have written a sample code below.

Referring to the delete button as StandardAction::Delete seems to work in the list report page.

Setting the anchor as any other existing button works as well

(e.g. "anchor": "DataFieldForAction::MyService.MyAction2").

I don't understand what I am doing wrong here? Is this functionality supported?

Thanks,

Atakan

Sample code:

annotations.cds
-----
...
annotate MyEntity with @UI : {
    ...
    Identification : [
        {
            $Type : 'UI.DataFieldForAction',
            Action : 'MyService.MyAction',
            Label : 'My Action'
        }
    ],
    ...
}
-----

manifest.json (in "sap.ui5".routing.targets)
-----
"MyObjectPage": {
    ...
    "options": {
        "settings": {
            ...
            "content": {
                "header": {
                    actions: {
                        "DataFieldForAction::MyService.MyAction": {
                            "position": {
                                "placement": "Before",
                                "anchor": "StandardAction::Delete"
                            }
                        }
                    }
                }
            }
            ...
        }
    }
}
