RESTDataSource.removeData() does not remove the selected rows from ListGrid.

Technical Q&A
1

I am using SmartClient8.0.
When I remove the records selected in a ListGrid, the records are actually deleted from database, but the rows are still in the ListGrid. What can I do to remove the records as well as from ListGrid.

The code I’m using:

isc.RestDataSource.create({
	ID: "application",
	fields: [
		{name:"id", hidden:true, primaryKey:true},
		{name:"name", title:"NAME"},
		],
		dataFormat: "json",
		removeDataURL:"application_delete.htm"
	});

isc.Button.create({
			ID: "removeButton",
			title: "delete",
			click: function()
			{
				application.removeData(appList.getSelection());
			}
		});

isc.ListGrid.create({
		ID:"appList",
		dataSource: application,
		width:"100%",
		canEdit:false,
		autoFetchData: true
	});

What do you return in application_delete.htm?

It should be something like that:

{"response":{"status":0,"data":{"id":"value_of_primary_key_for_deleted_record"}}}

With header Content-Type: application/json; charset=UTF-8

In case you are searching for the answer to this problem, got this far, and the problem isn’t yet answered, also check that you have only one field with “primaryKey: true” set. If you do have a composite key, you might be able to return both values in the response from the server (I haven’t checked this).
