Novell ZENworks Configuration Management 11.2 ZENworks Control Center - ZCC
This issue occurs when creating a new filter in the registration rules section under Configuration->Registration->New Rule in the ZENworks Control Center. When a new filter is added, there is an immediate field for the "NOT" option at the left of the filter. If this field is set to "NOT", it will be reset to its default when the next field (where the actual type of filter is selected) is chosen.
Fix was made in 11.2.3 so the "NOT" operator is now considered when selected, keeping it from resetting when an additional filter is added.
While choosing actual filters, the "NOT" operator selection was not considered. that is why default value was selected.
