Giatri,
Answers to your original questions,
1. Where in the FeatureServiceManager.qml should the NetworkRequest object be placed.
Anywhere as long as it is inside the main Item component
Item{
.....
.....
}
preferably toward the bottom so that they are in the same area with other NetworkRequest components in this qml file
2. How do I call the emailHandler in the applyEdits function.
By calling the send() function, you can refer to the applyEditNetworkRequest in the same file to see how it is being used to call the NetworkRequest component.
Hope this helps,
Erwin.
