This is my current way of doing editing of an existing order:
1. Search the order and store ALL the data into value node.
2. Transfer all the value node's values into model node. These model node are Context Bound to the UI so that one the click of "Save", all these values will be changed/saved successful.
Any comments on this way of doing? Is the transferring of all the data into value node first then transferring to model node redundant? It is abit troublesome because the node needs to contain lots of data due to the number of fields an Order has.
