JIRA Multi select复选框customfield无法正确更新

Question

I have a transition screen from which I am getting values(s) via a checkbox control, I need to get these values and update them on another checkbox control in the issues view screen. The below code updates the values but doesn't change the checkbox to checked.

   platvalue = issue.getCustomFieldValue(platRelOnField) //platRelOnField is the field from where I am getting my values to be set , it has 3 options [High,Low,Medium]

    ModifiedValue mVal = new ModifiedValue(issue.getCustomFieldValue(platRelOnAPIField),platvalue); 

    platRelOnAPIField.updateValue(null, issue, mVal, new DefaultIssueChangeHolder());

I am new to groovy/jira and cant seem to know the right way to set the checkbox options properly.

Any help in the right direction is appreciated.

I am using JIRA 6.3.9

Answer 1

Managed to get it working by writing the below code

ArrayList<LazyLoadedOption> optionsList = new ArrayList<LazyLoadedOption>();

FieldConfig fieldConfig = platRelOnAPIField.getRelevantConfig(issue);

OptionsManager optionManager = ComponentAccessor.getOptionsManager();

platOptions = optionManager.getOptions(fieldConfig);

for(def i = 0;i<platOptions.size();i++){
    def optVal = platOptions.get(i).getValue();
    if(platOptions.get(i).getValue().equals("custom field value")){
      optionsList.add(platOptions.get(i));
    break;
    }
}
platRelOnAPIField.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(platRelOnAPIField), optionsList),changeHolder)
