Groovy Script Cast Exception

[Yogesh Mude]

As m getting the list of incomplete issues from the sprint, i want to reset the sprint field of those incomplete issues to null.

i tried with the below code but getting error.

import com.atlassian.jira.bc.issue.IssueService;
import com.atlassian.jira.component.ComponentAccessor;

@WithPlugin("com.pyxis.greenhopper.jira")

@BaseScript CustomEndpointDelegate customEndpointDelegate

String sprintId = event.sprint.getId();
//def sprint = event.sprint;

ApplicationUser user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
System.out.println("Sprint Name : " + event.sprint.getName() );

def sprintManager = PluginModuleCompilationCustomiser.getGreenHopperBean(SprintManager)
def historicSprintDataFactory = PluginModuleCompilationCustomiser.getGreenHopperBean(HistoricSprintDataFactory)
def rapidViewService = PluginModuleCompilationCustomiser.getGreenHopperBean(RapidViewService)

def userManager = ComponentAccessor.getUserManager()
def issueService = ComponentAccessor.getIssueService()

def closedSprint = sprintManager.getSprint(sprintId.toLong()).value
def view = rapidViewService.getRapidView(user, closedSprint.rapidViewId).value
def sprintContents = historicSprintDataFactory.getSprintOriginalContents(user, view, closedSprint)
def sprintData = sprintContents.value
def sprintField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Sprint");

if(sprintData != null)
{

def incompleteIssues =sprintData.contents.issuesNotCompletedInCurrentSprint*.issueId;
System.out.println("Incomplete Issues : " + incompleteIssues);
if(incompleteIssues != null)
{
for(int i=0;i < incompleteIssues.size();i++ )
{
//String value = null;
System.out.println("Issue Key : " + incompleteIssues.get(i).toString());
MutableIssue mutableObject = (MutableIssue)incompleteIssues;
mutableObject.setCustomFieldValue(sprintField, null);
ComponentAccessor.getIssueManager().updateIssue(user, mutableObject, com.atlassian.jira.event.type.EventDispatchOption.ISSUE_UPDATED, false);
}
}

}

[Payne]

You're attempting to cast your list of issues, rather than the current issue in the loop, to one MutableIssue object.

Rather than

MutableIssue mutableObject = (MutableIssue)incompleteIssues;

You need something like

MutableIssue mutableObject = (MutableIssue)incompleteIssues.get(i);

...I think it is even worse... you try to cast a list of issueIDs to one issue ??:-(

You should for all the issueIDs in the list, instantiate first the issue (and cast it to MutabelIssue) , and then ....
