What would be the recommended way to open a TXDataWebDataset for data entry - i.e. an empty dataset which will post back to an xdata server as records are added?
Is it ok to just call Open, or perhaps set the query to a nonsensical selection like $filter=(Id eq -1) and call Load?
You can simply call Open. If you have EntitySetName and Connection properties set to valid values, it will send new data to the server when you call ApplyUpdates.
