How to solve the repeated rendering problem in SelectCFType?

[Wenjing Liu]

Hi all, I'm developing a jira plugin custom field extends SelectCFType class, and I Override the OptionsManager.getOptions() function, but when I refresh the portal, the options will be rendered repeatedly like below. Could anyone solve this?

And here's my getOptions funciton.

@Override
public Options getOptions(FieldConfig fieldConfig, JiraContextNode jiraContextNode){

    try {
        List<Option> options = new ArrayList<>();
        IQLFacade iqlFacade = ComponentAccessor.getOSGiComponentInstanceOfType(IQLFacade.class);
        String iql = "Key != \"\"";
        List<ObjectBean> assets = iqlFacade.findObjects(iql);

        log.debug(assets.toString());

        for(ObjectBean asset : assets){
            String key = asset.getObjectKey();
            Integer id = asset.getId();

            log.debug(key);
            log.debug(id.toString());

            options.add(ComponentAccessor.getOptionsManager().createOption(fieldConfig,null,Long.valueOf(id),key));
        }
        log.debug(options.toString());

        return new OptionsImpl(options,fieldConfig,ComponentAccessor.getOptionsManager());

    } catch (InsightException e) {
        throw new RuntimeException(e);
    }
}

Any adivce will be appreciated. Thanks in advance.

Hi @Wenjing Liu  

The root cause of the problem is the line below:

options.add(ComponentAccessor.getOptionsManager().createOption(fieldConfig, null, Long.valueOf(id), key));

This line creates new Option instances every time the field is rendered. Every time this code runs, it adds the new Option to the database.

You must retrieve existing options, not create new ones each time. Options should be defined once (e.g., during configuration or plugin install) and only fetched during rendering.

Something like the below would work for your case

@Override
public Options getOptions(FieldConfig fieldConfig, JiraContextNode jiraContextNode) {
List<Option> existingOptions = ComponentAccessor.getOptionsManager().getOptions(fieldConfig);
return new OptionsImpl(existingOptions, fieldConfig, ComponentAccessor.getOptionsManager());
}
