script runner validator- select list field is empty

Hello

I am trying to create script runner validator that should check select list custom field and another field based on select list field.

E.g. I have select list FieldA with values "Yes", "No" and "None" (empty). I need to check if FieldA is "Yes", then "FieldB" should be > 0. So my current working validator is

(cfValues['FieldA'].getValue() == "Yes" && cfValues['FieldB'] > 0) || (cfValues['FieldA'].getValue() == 'No')

But I need also to check if fieldA is "None", and I am unable to find correct statement for it I tried

(cfValues['FieldA'].getValue() == "Yes" && cfValues['FieldB'] > 0) || (cfValues['FieldA'].getValue() == 'No') || (cfValues['FieldA'] == null)

but it seems it is doesn;t work

What is the correct statement? Is it possible to optimize validator expression (without writing expression in one row) e.g.:

if(fieldA=="Yes"){
   if(fieldB<=0){
      //Validator was NOT passed
      // show message
   }
   else{
      //validator was passed
   }
}
else{
   //validator was passed
}

Thank you in advance,

Fyodor

It's better to use Groovy Truth than comparisons with null. So to check if it has a value:

if (cfValues['FieldA']) ...

to check if it doesn't have a value:

if (! cfValues['FieldA']) ...

You don't need to write it in one line, if you hit enter the text box will expand. Seems to be a common misconception that it must be a one-liner... bad UI design probably.

If it's clearer to write it in 10 lines with "if"s and "return"s then definitely do that.

Hey there,

"!= null" instead off ">0" could work and
you could check if you imported all nessesary data.
Like "import com.atlassian.jira.issue.Issue;"

That was often my problem ..

Hope this can help.

Hello Jamie and Simon.

Thank you for fast reply.

Could you describe me how can I put multi-row code? Expression should return TRUE (see screenshot), so I don't understand how can I put code with if, else etc ?

Could you show me an example?

Plugin version is 2.1.17

Best regards,

Fyodor

Like:

if (1) {
    return true
}
else {
    return false
}

am I missing someting?

The return keyword is actually optional for the last statement executed, but you can put it in for clarity.

Hello Jamie

Thank you for assistance, it works.

@Jamie Echlin [Adaptavist] I have a Q too:

 

 I would like to reject the option for setting the "Fixed in version/s" filed as long as the "Affects Version/s" field is empty

how should I write it with script validator? 

Hi Shelly


If you trying to update field's value based on another field, I think it will be better to use post-function or listener, not validator

If you need validator that checks issue's fields you can use something like:

result=true
if (cfValues['CustomFieldA']){
    if (cfValues['CustomFieldB'].getValue() == "Yes") {
            if(cfValues['CustomFieldA'] <= 0){
                result=false;
            }

    }
}
return result;

 

This °validator checks "CustomFieldA" (number custom field) value when 'CustomFieldB' (select custom field) has YES value.

Thanks Fyodor,

 

What I need is that:

if field A is empty/null than field B will be grey out - meaning, there will be no option to add value to this field. or make field B disappear 

 

Hmm....

I think it could be configured by behavior (Manage Addons -> behaviors....), but I haven't tried this functional yet....

Other possible soltuion - create postfunction or listener that updates one field value based on another field value.
Something like this listener example:

.....
MutableIssue issueToUpdate = (MutableIssue) event.issue;
def acceptedIssueTypes = ["typeA", "typeB"];
if(issueToUpdate.getIssueType().name in (acceptedIssueTypes)){

//some value
def someval = 100;

//find specific custom field
def CF = customFieldManager.getCustomFieldObjectByName('CF');

//set CF field and fire update issue event
issueToUpdate.setCustomFieldValue(CF, someval);
issueManager.updateIssue(event.getUser(), issueToUpdate, EventDispatchOption.ISSUE_UPDATED, false);

}
