Writing changes from editable datagrid back to local data store - Adobe Air/Flex

Question

Hi

I am using Adobe Air to get data from SalesForce, and present it in a datagrid.

I am using a query to get the data, and then put it into an arraycollection that is bound to the datagrid, this works correctly and the data is displayed.

I have made the datagrid editable, and I am able to change the values in the datagrid, but I cannot find how to save the changes to the local database.

I am using the following code:-

protected function VisitReportGrid_changeHandler(event:ListEvent):void{ app.wrapper.save(VisitReportGridProvider) }

But this has the following error when I try and compile it:-

1067: Implicit coercion of a value of type mx.collections:ArrayCollection to an unrelated type mx.data:IManaged.

Obviously I am doing this wrong, but I cannot find the correct syntax.

Thanks in advance for your help

Answer 1

This code is not enough to understand where actually is the problem Need to know what is VisitReportGridProvider, what is wrapper.save() method.

**after comment:

F3DesktopWrapper.save():

          public function save(item:IManaged):void

Saves the specified Managed object to the local database. You must make an explicit call to syncWithServer() to update the data on the salesforce server. However, do not call syncWithServer() too often (batch your save calls) as this may use up your alloted API usage. If the item is in conflict, the conflict will be resolved.

Parameters:

item:IManaged — The managed object to create or update.

you're passing parameter with type ArrayCollection which doesn't implement IManaged interface.

Answer 2

You need to pass the item in the ArrayCollection that was changed to the save function. Like:

acc.fieldCollection.updateObject(new AsyncResponder(function(o:Object, t:Object):void {
  app.wrapper.save(o as Account);
}, function(e:Object):void {

}));
