ComboxBoxItem with pickListProperties: {progressiveLoading: true} issues too many requests on pickList open

[Blama]

Hi Isomorphic,

explaining progressiveLoading and dataFetchMode I noticed that there is something not working as expected.
In my application (latest 6.1p) a SelectItem with progressiveLoading does skip the COUNT(*)-statement (which is good), but requests all rows of the DS, which is not expected.

I tried to reproduce in the SmartClient showcase and there is also an issue, but a different one. Please see this modified sample (v11.1p_2018-02-21) and the requests issues on pickList open:

isc.DynamicForm.create({
    width: 500,
    numCols: 4,
    isGroup: true,
    groupTitle: "List - ComboBox",
    wrapItemTitles: false,
    fields : [{
        name: "bugStatus", title: "Bug Status", 
        editorType: "ComboBoxItem",
        valueMap : {
            "new" : "New",
            "active" : "Active",
            "revisit" : "Revisit",
            "fixed" : "Fixed",
            "delivered" : "Delivered",
            "resolved" : "Resolved",
            "reopened" : "Reopened"
        }
    },{
        name: "itemName", title: "Item Name", editorType: "ComboBoxItem", 
        optionDataSource: "supplyItem", pickListWidth: 250, [B]pickListProperties: {progressiveLoading: true}[/B]
    }]
});

This is minor for me.

The ComboBoxItem uses progressiveLoading by default. Explicitly setting the property on the pickListMenu is causing the full dataset to be loaded a page at a time.

So why are you trying to enable a default setting?

Hi Isomorphic,

I have FetchMode.LOCAL set on some ComboBoxItem where I know they will have only a few entries and wanted to explain the difference to progressiveLoading. So it was more of a test.
