Hi,
I've posted on here previously about trying to create something akin to an HMI using Node-Red. I've got a setup that is "working" currently. I have some user parameters that I want to set, and then send onwards to a device via MQTT.
The problem I'm having is that the behavior of the text input node is not what I would expect. I have 3 text input nodes designed to take numbers as input, and pass them on to MQTT once the user presses a RXN Start button. This all works as expected. The issue arises when the user stops the reaction, or tries to modify a parameter. When this happens, only the modified value is sent instead of the currently populated fields of the other text inputs. This is very confusing from a user perspective since you would expect it to send the current value of each field.
Is there an accepted solution to this problem?
