BUG REPORT: Realtime Messaging backward compatibility issue

[lpolvani]

We are in the process of upgrading from SmartGWT 5 to 12. Our backend is already up to date, while we are still migrating the frontend.

Problems arise when we try to use realtime messaging from a client compiled with SmartGWT 5 against a v12 backend.

The message formats are different. V12 client expects message to have attribute “connectionID”, V5 expects message to have attribute “conn”

Using the console to send the message, we can get the callback to fire. we just changed “connectionID” in the message to “conn”

This would be expected not to work. You can’t mix different versions of our front end and backend software, and warnings will be logged in the console if you attempt this.
