How to work with data sources from workflows in Experience Builder

Hi,

I am having trouble converting a workflow that was used in WAB to ExB.  The workflow uses the following:

• Add Feature Layer
  • uses a feature collection as input; this works fine in WAB but returns layer: undefined in ExB deployment. What am I missing to get Add Feature Layer to work for ExB?
• Set Layer Pop-up 
  • not compatible with ExB; trying to do this by hand with Set Layer Property for $addFeatureLayer1.layer.id for property popupTemplate with value ={
    title: 'Query Result - {NID_ID}',
    fieldInfos: [
       {
           "fieldName": "NID_ID",
           "label": "NID ID",
           "isEditable": false,
           "visible": true
       },  etc.
       {
           "fieldName": "NEXT_INSPECTION_DATE",
           "label": "Next Inspection Date",
           "isEditable": false,
           "visible": true
       }
    ]
    }
  • unable to test since there is no layer.id from the above step
• Delay
• Evaluate Expression (Workaround to make sure popups are enabled by default on result layer)
• Get Feature Set Extent
• Set Map Extent
• Send Layer to Attribute Table
  • Also not compatible with ExB, would like to do a workaround by setting up a dataSource dynamically but can't figure this out.

  I have also found that we are getting layer:null pretty regularly when trying to create features (graphics).

  Was able to get everything resolved, EXCEPT Send Layer to Attribute Table.

   

  Is there any way to use VertiGIS Workflow to handle this?

  For my own notes, I believe the fix was to make sure the VertiGIS Widget in ExB was pointing to the Map widget, to properly format the fields list & symbology, and return geometry properly to load into the Add Layer to Map task.
