In Thingworx standard training, after creating temperature and humidity widgets, when i try to set the value, it doesnt show up in the dial
pls see the attached document
could it be that you haven't refreshed the widgets after the service that sets the new value runs (when the set button is clicked?).
To do this select the service in the data window, then drag the 'ServiceInvokeComplete' event back onto the service that supplies the data to your widgets, as this will run that service again and refresh your widget with the new data.
