ID: 0057 Title: Fix exception in WATO host editor on custom tag without topic Component: WATO Level: 2 Class: Bug Fix Version: 1.2.3i8 When you've defined a host tag group in WATO that has no topic, then the host edit dialog would be interrupted with an exception. A simple workaround to this is to alwasy define a topic. The problem has now been fixed. It had shortly been introduced by fixing a problem appearing when you used a slash in the name of a tag group.
