Separator not showing in Adaptive Cards

Question

I've been trying to get the "separator" property of Adaptive cards to work, but it does not seem to be rendering in the BotFramework Emulator.

Here are images to the Emulator and the Visualizer for the same code: Emulator Visualizer

The code in both places is the same, and is as follows:

{
    "contentType": "application/vnd.microsoft.card.adaptive",
    "content": {
        '$schema': 'http://adaptivecards.io/schemas/adaptive-card.json',
        'version': '1.0',
        'type': 'AdaptiveCard',
        'body': [
        {
            'type': 'TextBlock',
            'text': 'Meeting Title',
            'weight': 'bolder'
        },
        {
            'type': 'TextBlock',
            'text': 'Location',
            'separator': true,
            'isSubtle': true,
            'size': 'small'
        },
        {
            'type': 'TextBlock',
            'text': 'Location',
            'spacing': 'none'
        },
        {

            ]

        {
            'type': 'ColumnSet',
            'spacing': 'none',
            'columns': [
            {
                'type': 'Column',
                'width': 'auto',
                'items': [
                {
                    'type': 'TextBlock',
                    'text': '05:30 PM',
                    'isSubtle': false,
                    'weight': 'bolder'
                }
                ]
            },
            {
                'type': 'Column',
                'width': 'auto',
                'items': [
                {
                    'type': 'TextBlock',
                    'text': 'May 21'
                }
                ]
            },
            {
                'type': 'Column',
                'width': 'auto',
                'items': [

                    'type': 'TextBlock',
                    'text': '2017',
                    'isSubtle': true,
                    'weight': 'bolder'
                }
                ]
            }

            ]
        }
        ],
        'actions': [
        {
            'type': 'Action.Submit',
            'title': 'Accept',
            'data':{
                'accept': true
            }
        },
        {
            'type': 'Action.Submit',
            'title': 'Decline',
            'data':{
                'accept': false
            }
        }
        ]
  }
}

As seen, The separators appear only in the visualizer, for the same code. Am I missing something?

Answer 1

it might be a little bit tricky because the separator documentation is a little bit vague (at least for me).

Take a look here - the syntax purposed to separator doesn't seem to work anywhere.

What I did find:

• The spacing property works just fine (at least with these values "none" | "small" | "default" | "medium" | "large" | "extraLarge" | "padding")
• It will only works when using in containers (Container, ColumnSet, Column, etc.)
• It is also apply (as the name implies) on the outer area of the container (similar to CSS margin property)
• Will not work for the first container

You may go to the adaptive cards classic editor and put spacing (let's say "spacing": "large") on the second Container section (there are only 2 of them) and observe the spacing impact by yourself

Answer 2

Instead of separator you can use Separation = SeparationStyle.Strong this is working for me
