How to create a custom field like Components field?

[zaharovvv_suek_ru]

Hey, guys!

What I want is to create custom button which is the same like Component/s button:

So I need to have the content of Component/s button and behaviour of Component/s button in custom button.

I've tried to create a custom button and put this code inside of "Description":

(function($){
 new AJS.MultiSelect({
 element: $("#customfield_10653"),
 itemAttrDisplayed: "label",
 errorMessage: AJS.params.multiselectComponentsError
 });
})(AJS.$);

However, the above code is not working and I see just the above code.

Guys, how can it possible to create custom field like "Component/s" button?

I have an option to use ScriptRunner.

Hello @zaharovvv_suek_ru

As I can remember, you are using scriptrunner

Component/s field it's just like labels field, so why not try to create labels field that will be populated from components via listener on Issue Update event?

@Mark Markov yeah, you are right! 

Thanks for your reply.

It sounds really good. However, I am not really aware how it is possible to populate by components and what does "via listener on Issue Update" event. Could you be very kind to clarify that?

[Mark Markov]

Jira based on event architecture. When something happens(changes) in system, jira thtows an specific event(for example, when you made some changes to the field values, jira throws ISSUE_UPDATED event), that can be caught and processed by listeners. To make listener with Scriprunner go to add-ons -> Script listeners -> Add -> Custom script listener

Project key: What project lister will be affect

Event: On what event it will be triggered (in your case Issue Updated)

Inline/file script: And your script that will do all kind of magic you need.

Here is example of script that will catch changes of Component/s field:

def change = event?.getChangeLog()?.getRelated("ChildChangeItem")?.find {it.field == "Component"}

if (change) {
    log.debug "Value changed from ${change.oldstring} to ${change.newstring}"
 // your actions if the field has changed
}

@ Huge thanks! You make it clearer! Now it is really clear about events. 

However, is it possible:

1. To get components and populate custom field by this components? I mean like Components field.

2. To have behaviour like Components field - when I input letter in custom field, then autosuggestion of components will work?

@zaharovvv_suek_ruYou don't need to  create a  new one,  we have the component/s

field,  

• Just go to knowledge base here see how to  Configure component
• this values  for the component  will  appear on the screen as you already have this  field  added to screen .

Why you  want to  complicate things ?

Best!

@Moses Thomas yeah, I know, however I was asked by my chief to create the same custom field "ComponentsLinked" which looks exactly the same like "Component/s" field and set Components value  in that custom field. 

So I cannot protest to his requirements.

Is it possible to create such a field?

@zaharovvv_suek_ruI think its not designed for you to  add a system field.

@zaharovvv_suek_ru

Please KB article on  how to add new custom field Add custom field

What  do  you  hope to  achieve?  component field is a system  field  by  default.

Best

Thanks for your reply, Moses. I can add custom field, however I cannot create a custom field which is populated by components.

What I want is to create custom field "ComponentsLinked" which looks exactly the same like "Component/s" field and set Components value  in that custom field. 

How can I do it?
