I am writing a trigger that has an IF clause based off of a field. However, I cannot get it to recognize if that picklist is blank. I have tried:
field.isblank()
string.isblank(field)
field == ''
field == '--None--'
field == NULL
None of these catch when there is no value. Prior to saving the record, the field says 'deleted' if I set it to --none--...but I'm not sure how to check that value within a trigger.
Thank you!
