subtask validation from parent's field used JMWE

[Tyas Iglecias]

Hi guys,

I have 3 field :

1.  Vendor (A) : Text Field (multi-line) 12038
2.  Developer (B) : User Picker (multiple users) 12443
3.  SQA (C) : User Picker (multiple users) 12444

fields will be filled in Parent workflow,

I will make validation in sub-task used Linked Issues Validator (JMWE app)

Status Movement from open to in progress if :

A Empty + B Empty +C Empty= stop
A Empty + B filled +C Filled = move
A filled + B filled +C Filled = move
A filled + B Empty +C Empty = move

but I try my script and the result not same with my needs

(linkedIssue.customfield_12038 == null && linkedIssue.customfield_12443.length == 0 && linkedIssue.customfield_12444.length == 0)
||
(linkedIssue.customfield_12038 == null && linkedIssue.customfield_12443.length > 0 && linkedIssue.customfield_12444.length > 0)
||
(linkedIssue.customfield_12038 != null && linkedIssue.customfield_12443.length > 0 && linkedIssue.customfield_12444.length > 0)
||
(linkedIssue.customfield_12038 != null && linkedIssue.customfield_12443.length == 0 && linkedIssue.customfield_12444.length == 0)

the result  :

A Empty + B Empty +C Empty= stop
A Empty + B filled +C Filled = move
A filled + B filled +C Filled = move
A filled + B Empty +C Empty = stop

please help me for corrections related to what i have made

Regards,
Tyas

Apparently, Jira expressions return "" for an empty multi-line text field (instead of null). Therefore, the script should be:

(!linkedIssue.customfield_12038 && linkedIssue.customfield_12443 != null && linkedIssue.customfield_12444 != null)
||
(!!linkedIssue.customfield_12038 && linkedIssue.customfield_12443 != null && linkedIssue.customfield_12444 != null)
||
(!!linkedIssue.customfield_12038 && linkedIssue.customfield_12443 == null && linkedIssue.customfield_12444 == null)

Hi @David Fischer ,

After used your script, result is :

A Empty + B Empty +C Empty= move
A Empty + B filled +C Filled = move
A filled + B filled +C Filled = move
A filled + B Empty +C Empty = move

Are there any settings I missed?

Hi @Tyas Iglecias ,

that's probably because, when a multi-user picker field is empty, it doesn't return an empty list but null. Therefore, you should not test the length against 0 but the field against null. Also, your first test is incorrect, since it will pass if all 3 fields are empty. Generally, you need to think in terms of every case where the validator should pass.
