Table.columns.queryName property not updated after changing the aggregate function

[victoriaacqua]

I've created the following custom visual using a table Data View Mapping. If I added a column to my GroupingOrMeasure Data Role the table.columns.queryName property of this column takes the value of the first summarization option (which is sum): "Sum( Table.Column1 )".

But if I change the aggregate function of this column to "Don't Summarize" (or any other), the queryName property doesn't update at all, is still "Sum( Table.Column1 )":

Exploring Custom Visual DataView

Steps to reproduce this issue

1. Create the following table:

Adding data to a new table

2. Create a custom visual with the following capability:

• Data Roles:

"dataRoles": [
        {
            "name": "columns",
            "kind": "GroupingOrMeasure",
            "displayName": "Columns"
        }
    ]

• Data View Mapping:

"dataViewMappings": [
        {
            "table": {
                "rows": {
                    "select": [
                        {
                            "for": {
                                "in": "columns"
                            }
                        }
                    ]
                }
            }
        }
    ]

3. Explore table.columns.queryName value with Show DataView button and see how this property is not updated after changing the aggregate function of Column1.
