Is it possible to call a method from Customfield?

Question

Hello,

I have created a customfield and I have different methods to get the value. E.g. I have a method getValueWithId(). So the value of the customfield shows the let`s say lastName and the getValueWithId is personId, lastName. I am able to get the customfieldvalue as follows:

final CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();

final CustomField customField = customFieldManager.getCustomFieldObjectByName(CONTACT_CUSTOM_FIELD_NAME);

if(customField != null) {
	    	final Object customFieldValue = getIssueObject().getCustomFieldValue(customField);

if(customFieldValue != null && customFieldValue instanceof String) {
	    		String newCustomFieldValue = (String)customFieldValue;

Now I want to access the customField value from a class that extends a JiraWebActionSupport. I am able to access the value, but I want to directly call the getValueWithId() method from the customField class.

It`s all working as expected, my only problem is, that I have duplicated code within the customField and the class that extends the JiraWebActionSupport.

Thank you.

I tried this by checking the name of the returned customField object.

LOGGER.debug("customField: " + customField.getClass().getName());

writes

customField: com.atlassian.jira.issue.fields.CustomFieldImpl

But thats not my class. My class is EmailNotificationCustomField extends GenericTextCFType. Maybe it`s that easy as you describe, but where do I cast?

If you cast your customfield to the right class, you can use the method of that class right?
