How to get other field value for Custom Picker field

[Jakub Gawinkowski]

Hi,

I’m trying to configure dynamic multi-select Custom Picker field “Hyp. Mitre Techniques“. Values show by that field should depend on value from multi-select Custom Picker field “Hyp. Mitre Tactics“.

“Hyp. Mitre Tactics“ is developed and working fine. I can’t read value of this field in my script for “Hyp. Mitre Techniques“. I’m trying to do it following way

import com.atlassian.jira.issue.Issue
Issue issuedef mitre_tactic = issue.getCustomFieldValue("Hyp. Mitre Tactics")

But it results in error

java.lang.NullPointerException: Cannot invoke method getCustomFieldValue() on null object	at Script285.run(Script285.groovy:6)

How can I get value of other field in Custom Picker?

Here is my code for both fields

Hyp. Mitre Tactics

search = { String inputValue ->

    }

}

getItemFromId = { String id ->

}

toOption = { Map<String, String> option, Closure highlight ->

            html: "${highlight(option.tactic, false)}"

    )

}

renderItemViewHtml = { Map<String, String> option -> 

    "$option.tactic"

}

renderItemTextOnlyValue = { Map<String, String> option -> 

    option.id

}

I resolved my problem. I had to define issue in inputs for search function and in getItemFromId function I had to provide list of all possible options. After that I was able to read field value inside that functions.

I created additional technique_searcher function to prepare filtered options list for "search" function and all options list for "getItemFromId" function

import com.onresolve.scriptrunner.canned.jira.fields.model.PickerOption

import org.apache.commons.lang3.StringUtils

def technique_searcher(issue) {    

    def picker_options = [

Hi @Jakub Gawinkowski 

In the context of ScriptRunner, you use issue directly, you don't need to define it. remove this definition

Issue issue

and use something like below

def customFieldManager = ComponentAccessor.getCustomFieldManager() 
def tacticField = customFieldManager.getCustomFieldObjectByName("Hyp. Mitre Tactics") 
def mitre_tactic = issue?.getCustomFieldValue(tacticField) 
if (!mitre_tactic) { 
   mitre_tactic = [] 
}
...

Hi @Tuncay Senturk 

I tried to do it like that but it shows that "issue" is undeclared

[Tuncay Senturk]

Did you try to run it? Sometimes the editor shows compile errors but it may run ok.

[Jakub Gawinkowski]

Yes i tried. I returns following error

groovy.lang.MissingPropertyException: No such property: issue for class: Script269
 at Script269.run(Script269.groovy:12)
