Losing device in temperature control

[johnnyt]

Have set up an event based on a temperature control that looks for the average of 2 humidity sensors to "decrease to lower limit" and set the lower limit value to "s3", a device with a value I calculate periodically.

Trouble is when I double click the event, the value "s3" disappears from the lower limit box. I see it in the "trigger" column but it disappears when I open the event and stays gone if I click OK.

I have explicit checks for numeric values when formatting the entry for display on the form. I dont recall why I did that. I removed them so the next build will allow the devices to be displayed there.
