WOW can optionally use Websocket API to send messages to your server and receive event-driven responses (updates, deletes, inserts) without user having to hit the server for a reply.
This is set up by adding property into TableDisplay property group: websocketsRefresh:true
As an example, I would first need to create an operation to return data:
Upon running this operation, I get an updatable table of data:
To demonstrate, notice how I have two datasets labeled with "User 1".
Next, I need to create another operation showing the results in table display. This is also the operation where I need to set the TableDisplay property group: websocketsRefresh:true as shown here:
This will render this result:
Notice in my User 1 column I have a total of 120 but remember upon entering the data in the original table, there were two entries for User 1. The above image represents the TOTAL of both. Now, if I were to enter a new value for the User 1 and click update, the grouped data will automatically refresh without re-running the operation.
