I'm using scriptrunner's issuefunction expression to compare two custom date fields in a jql. Example: issueFunction in expression("", "dateField1 < dateField2"). I'm having trouble when one of the custom fields have a dash in it, scriptrunner doesn't recognize the name of the field. When a field is called "date field 1", writing datefield1 on scriptrunner works. When a field is called "date - field 1", writing date-field1 on scriptrunner does not work.
Is there a particular way to escape dashes for custom field names in that situation?
