•

onEditSaveClick—Commits the updated object to the local database.

•

onEditDeleteClick—Deletes the record from the local database, updates the status, and displays a toaster alert.

•

onEditCancelClick—Cancels the current edit operation.

_editFieldContainer.fieldCollection.updateObject(

new mx.rpc.Responder( commitToDB, saveFaultHandler )

);

}

protected function onEditDeleteClick() : void {

_app.setStatus( null );

var account : Account = Account(

_editFieldContainer.fieldCollection.managedObject

);

// clear and go back to empty mode

_editFieldContainer.fieldCollection.clear();

currentState = "default";

_desktopWrapper.deleteItem( account )

var status : F3Message = new F3Message(

F3Message.STATUS_INFO,

"Account deleted"

);

// Show the message in the status bar.

_app.setStatus( status );

// Show the toaster.

_app.showToaster(

new Toaster(

StaticAssets.REPORT_IMAGE_32,

"Account deleted",

status.description

)

);

protected function onEditCancel() : void {

_app.setStatus( null );
