Select list cascading smart value isEmpty does not return TRUE or FALSE when it is emtpy

[Bin]

issue.customfield_xxxxx.value.isEmpty did not return TRUE if the field was empty.  But when I selected a value in the field, the same smart value returned FALSE.  So it works only when the field is not empty.

Does anyone experience the same or I did something wrong.

You can use the expression "equals" over the child value instead. Check this example:

{{equals(issue.Custom_Field_***.child, null)}}

This will return TRUE whenever the child is null and FALSE whenever some value is assigned. Note that I am referring to the child structure, not its content (child.value). Trying this on its value for some reason won't work.

Hi @Bin Liang 

Yes, I have seen the same behavior, and I have not found the isEmpty function to be useful due to this problem with handling null values as "empty".  

I recommend using other methods to detect an empty value.

Kind regards,
