I followed this tutorial and everything is fine. Only one thing: I would like to have my customField to NOT become hidden when there is NO value. I tried to work with view.vm: #if ($value) // shows the link #else Hello the value is Empty! But nothing shows up. CustomField is still hidden. Can you please give me some tips about where should I handle this? I'm working with JIRA 5.1.8 Thanks in advance.

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Ok. I found another solution (to override method getValueFromIssue):

@Override

@Nullable

public String getValueFromIssue(CustomField field, Issue issue) {

// TODO Auto-generated method stub

String value = super.getValueFromIssue(field, issue);

return (value == null) ? "" : value ;

}

JIRA is setup to not display most fields that don't have values. Your code may never get executed if there isn't a value

Iryna Laryionav

is there any way to handle it with javaScript or some other way?

I actualy tried to set e default value, but the field is still hidden.

Joe Pitt

If it has a default value and still hidden there is another problem. Make sure it is in the on the screen (at least view) and is defined to be available for the issue type/project

Iryna Laryionav

actually I've already checked and it's not on the view-issue-screen html page. as soon as there is no value the <div> for custom field disappears.

but it is assigned to Default Screen and it show up in Edit and Create Issue (and after adding the value)

You can control this from the your CFType class. If the getValueFromIssue method returns null, the velocity file will never get called. You can return an empty string or something to make it look like it has a value and then handle it in the velocity file.

Joe has pretty much said a lot of what I would already, so I won't repeat it.

I think you'll need to change code in the core of Jira. The reason is that the framework that draws the screen is making the decision whether or not to render the field, way before you look at the templates. I imagine an internal dialogue like

Jira: Oi, field on issue, you got data?
Field on issue: Yes
Jira: Ok, field definition, how do I draw this?
Field definition: here's some velocity and some data, and my display name
Jira: There you are user, some nice html with a field name, and some pretty data

And then:

Jira: Oi, field on issue, you got data?
Field on issue: No
Jira: Ok, next field...

That's better than I could explain it

Since we're talking about a "custom" custom field, we do have control over "Field on issue: Yes/No" using that getValueFromIssue(..) method in the CFType class by returning a null value for "No" and non-null for "Yes".

Iryna Laryionav

good dialogue

Thanks for advice it actually almost solved everythig, there's just one new problem:

i check the value in getVelocityParameters next way :

if (getValueFromIssue(field,issue)==null)

{

log.warn("Field was empty");

//createValue(field, issue, "Edit");

updateValue(field, issue, "Edit");

}

in both cases (create and update value) the field becomes only visible after the second visit of the view issue page if the issue at first didn't have customField.
