The text of the launcher buttons is changed to "---" when the device goes to fault (that's ok) but it is not recovered when the device gets running again
To reproduce:
- launch taurusdevicepanel and select sys/tg_test/1
- go to commands tab and launch "Switch States" command
- Now launch "Init" command
- Go back to the attribute panel, and see that the launcher button text will be "----"
Reproduced with debian9 and with win8.1
