cs-studio: Strange PVManager error
I keep getting this error from a BOY screen that uses this pv in a text input I’m not sure why only this pv.
2017-01-19 10:34:48 ERROR: Error from pv connection layer:
java.lang.IllegalStateException: ConnectionCollector for 'REA_BTS19:RFC_D0983:ON_RSTS_RF' was closed.
If I remove the text input, there is no error. If I paste the text input with this pv into a new BOY screen, there is no error. If I paste the text input back with this pv, there is the same error again.

Just guessing: The widget is started, connects to the PV etc. Meanwhile, to allow changing the PV name at runtime, there’s a listener for the pv_name property. It closes the old PV, connects to the new PV. Problem is that this handler seems to run right away, and with a bad oldValue. Maybe it was triggered by some code change to support macros etc, forcing a re-evaluation of all properties?
