- add a variable of type date to a process instance (e.g. name = "date" value = "2014-04-14T10:27:51")
- go to process definition view in cockpit
- filter by variable using: date = "2014-04-14T10:27:51"
- process instance is not found
- the process instance with this variable should appear in list on process definition view
Hint: probably the filter mechanism does not realize that this is a date and executes a like query as with any other string
