Trying to compare assignee fields as not being empty when checking out a computer

[Jim Poole]

In a transition, I want to validate that a computer leaving inventory to be checked out that a condition must be met.  The condition I chose was field assignee !=  (blank) or NULL according to documentation.  I also tried Unassigned.

Basically, I can't seem to use a Condition for a single field selection list or field Assignee to check that there is indeed a valid value other than None (for the single field list) or Unassigned for the field Assignee.  

Not sure of another way to get around this.  I don't like the idea of being able to move a computer from Reviewing (In Progress) to In Use (In Progress) and allow the Assignee field left as Unassigned.

BTW - this is Jira Cloud - not server or datacenter

Thank You

Hi Jim,

This might seem obvious but when you write the condition, do not write None or Null in the second field. Just leaving it blank will make the condition work. likne Assignee != [and leave this blank] it will appear as Null when you save. If you write None or NULL is comparing to those words as strings. (Happened to a collage).
If thats not the problem please send a screencap of how are you configuring it.

You should use "Validation" not condition, I guess. Do you see a "Field Required" validation in your workflow validation ? If you see, use that and select the field Assignee.
