Attribute Events gets missed

# 6 years ago
Reynald	Hi, This window in the ATK Diagnostic showing the listeners is showing only the listeners in your ATK application (ATKPanel in your case), so the number of listeners here does not corresponds to the number of Tango clients having subscribed to UTC attribute. The listeners listed here are internal Java objects in ATKPanel listening for some events occurring on this attribute. By the way, what are the other screenshots you attached? Cheers, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

Reynald	I would also encourage you to put less attributes per device if you can… For instance, in your case, we can clearly see you have many attributes starting with " Sub Array 1_" prefix… It would probably be better to create a device dedicated for this Sub Array 1. It is not a good practice to put everything into a single device. What surprises me the most is the name of some of the attributes… Maybe it's an optical illusion or a display artifact but it looks like some attributes are containing spaces in their names… For instance "MNC/CMC/AGN0/Sub Array 1_RA". Is the name "MNC/CMC/AGN0/Sub Array 1_RA" or "MNC/CMC/AGN0/SubArray1_RA"? Cheers, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new.
