Custom Connector: Changing Icons in Navigation Pane

[Beginna]

Hello, 

I want to build a nav table so I followed the documentation: 

https://learn.microsoft.com/en-us/power-query/handling-navigation-tables#examples

I tried to change the ItemKind of a row in the Simple Navigation Table, that is shown in the documentation. 

The documentation says this about ItemKind: "

Each of the following item kind values provide a different icon in the navigation table.

• Feed
• Database
• DatabaseServer 
• ..."

So I thought that changing the value for ItemKind in one row of the navigation table also changes to icon in the navigator. But nothing changes:

How can I change the Icon of one element in the navigator window?

Hello @Anonymous,

are you able to look into this matter?

I can provide more examples where the icons don't reflect the item type.

Thank you, @Anonymous  !!

But I still have this issue. Could you help me with that?

I would like to give you an example. 

I want to change the icon of Item3 to a table. I know that the data of Item3 shows a function. Therefore I change the ItemKind and ItemName to Table in the navTable: 

objects = #table(

            {"Name",       "Key",        "Data",                           "ItemKind", "ItemName", "IsLeaf"},{

            {"Item1",      "item1",      #table({"Column1"}, {{"Item1"}}), "Function",    "Function",    true},

            {"Item2",      "item2",      #table({"Column1"}, {{"Item2"}}), "Database",    "Database",    true},

            {"Item3",      "item3",     (a) => FunctionCallThatReturnsATable(),  "Table",    "Table",    true},            

            {"Item4", "item4", #table({"Column1"}, {{"Item2"}}),       "Table", "Table", true}

            }),

NavTable = Table.ToNavigationTable(objects, {"Key"}, "Name", "Data", "ItemKind", "ItemName", "IsLeaf")

// Common library code

Table.ToNavigationTable = (

    table as table,

    keyColumns as list,

    nameColumn as text,

    dataColumn as text,

    itemKindColumn as text,

    itemNameColumn as text,

    isLeafColumn as text

) as table =>

    let

        tableType = Value.Type(table),

        newTableType = Type.AddTableKey(tableType, keyColumns, true) meta [

            NavigationTable.NameColumn = nameColumn,

            NavigationTable.DataColumn = dataColumn,

            NavigationTable.ItemKindColumn = itemKindColumn,

            NavigationTable.ItemNameColumn = itemNameColumn,

            NavigationTable.IsLeafColumn = isLeafColumn

        ],

        navigationTable = Value.ReplaceType(table, newTableType)

    in

        navigationTable;

But I still get the function icon in the navigator:

Hi @Beginna ,

Try changing these two columns to the same value.
