updateCaches add operation not working?

[jason.saunders]

What am I doing wrong here, I click the test button which fires an updateCaches operationType: "add" but no record appears in the listgrid?

   var ds = isc.DataSource.create({
        fields: [ { name: "ID", title: "ID" } ]
    });

    var grid = isc.ListGrid.create({
        dataSource: ds
    });

    isc.Button.create({
        title: "add",
        top: 200,
        click: function () {
            grid.dataSource.updateCaches({ operationType: 'add', data: {ID: "xxx"} });
        }
    });

You did not declare a primaryKey.

[jason.saunders]

Added primaryKey but its still not adding the record. No javascript error and no smartclient debugger error apparent.

Current test case;

    var ds = isc.DataSource.create({
        fields: [ { name:"ID", title:"ID", primaryKey:true } ]
    });

    var grid = isc.ListGrid.create({
        dataSource: ds
    });

    isc.Button.create({
        title: "test",
        top: 200,
        click: function () {
            grid.dataSource.updateCaches({ operationType: "add", data: {ID: "xxx"} });
        }
    });

Another problem is that the DataSource has not fetched. Calling fetchData() will fix the problem, another route is to setData() with a ResultSet that has empty initialData (if you for some reason don't want to fetch).

[jason.saunders]

Thanks. Using either the fetchData or setData methods make the updateCaches "add" work.

For other readers in order to "...setData() with a ResultSet..." its not immediately obvious from the documentation that a ResultSet can be passed on a ListGrid.setData call. The ResultSet overview covers it though with "ResultSet can be passed to any component that expects a List"

To use it;

 var rs = isc.ResultSet.create({
        dataSource: ds,
        initialData: []
 });

 grid.setData(rs);
