There is a checkbox for the field value comparison that is Compare with original value (before the change)?
What functionality does this do? I looked at the docs (https://docs.civicrm.org/civirules/en/latest/basic-example-field-value-comparison-condition/) but didn't see an explanation.
My use case is I have a custom field that is a set of checkboxes. I am adding an activity based on a a specific custom field value being selected but I don't want it to do trigger my action (in this case an activity) each time the fieldset is saved if the value is already selected. I thought that this option may be checking if the field value changed but it still added the action.
FWIW, I created a regular group that the CiviRule adds them to. My condition checks Not in Selected Group [the group] to get it to work.
