Plugin Upgrade for JIRA 5 : How to get values from custom field (Cascading Select )

[Hussain Misbah]

Hi Everyone,

I have a custom plugin/events listener that I am rewriting to support JIRA 5.

but I am getting an exception , can anyone help fix this, or show a sample of how to get values from cascading select field using JIRA 5 SDK.

JIRA 4:

{code}

Issue currentIssue = event.getIssue();
IssueManager issueManager = ComponentManager.getInstance().getIssueManager();
MutableIssue mutIssue = issueManager.getIssueObject(currentIssue.getKey());
CustomFieldManager cfm = ComponentManager.getInstance().getCustomFieldManager();
CustomField customField = ManagerFactory.getCustomFieldManager().getCustomFieldObjectByName("MyCascadeSelect");
CustomFieldParamsImpl params = (CustomFieldParamsImpl) currentIssue.getCustomFieldValue(customField);

LazyLoadedOption option1 = (LazyLoadedOption) params.getFirstValueForNullKey();
LazyLoadedOption option2 = (LazyLoadedOption) params.getFirstValueForKey("1");

String value1 = option1.getValue();
{code}

JIRA 5

{code} Issue currentIssue = event.getIssue();
IssueManager issueManager = ComponentAccessor.getIssueManager();
MutableIssue mutIssue = issueManager.getIssueObject(currentIssue.getKey());
CustomField customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("MyCascadeSelect");
// System.out.println(customField.getCustomFieldType().getName()); //cascading select
// System.out.println(currentIssue.getCustomFieldValue(customField).getClass().getName()); //HashMap

HashMap value = (HashMap)currentIssue.getCustomFieldValue(inRegardsTo);
// System.out.println(value.size()); //2
// System.out.println(value.values().toArray()[0].getClass().getName()); // LazyLoadedOption

CustomFieldParamsImpl params = (CustomFieldParamsImpl) currentIssue.getCustomFieldValue(customField); // exception :
// java.lang.ClassCastException: java.util.HashMap cannot be cast to com.atlassian.jira.issue.customfields.view.CustomFieldParamsImpl

{code}

here is the solution to share :

LazyLoadedOption option1 = (LazyLoadedOption) params.getFirstValueForNullKey();

will become

LazyLoadedOption option1 = (LazyLoadedOption) value.values()toArray()[0];
