org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object issue while using export all fields to excel/xml

[Vijay Sv]

I am using Export (All fields) function to pull all the scripted custom fields, but logs are getting filled up with below error.

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'DocumentIssueImpl[issueKey=CDN-5922]' with class 'com.atlassian.jira.issue.DocumentIssueImpl' to class 'com.atlassian.jira.issue.MutableIssue'

Please let me what has to be done in this scenarios.

------------------------------------------------------------------------------------------------------------------------

Example scripted Custom Field:

-----------------------------------------------------------------------------------------------------------------------

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.util.IssueChangeHolder
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.MutableIssue

ComponentManager componentManager = ComponentManager.getInstance()
CustomFieldManager customFieldManager = componentManager.getCustomFieldManager()
String displayContent = "";
MutableIssue myIssue = issue;
def versions = myIssue.getFixVersions();

I got the solution for this i was using an issue object that is a document type class as an issue directly, need to convert from the issue document to an issue in this scenario.

1. Do you need to use Mutableissue instead Issue. It is requared if you want to update in issue. Here you need just to get some values
2. When you get custom field value for date you get  java.sql.Timestamp. object. You can have troubles to cust it to stirng here: commitValue!="". If you want to checj wether this field is empty you should use commitValue.getTime() != 0;
3. To speed up development see this: https://answers.atlassian.com/questions/32982259.

Thanks Vasiliy!! I am able to update in issue. Here the issue is, for example if the custom field "Deployed in Name" is part of Project "A" and issue Type "Task" & "Defect"(Screens) and for Project "B" it is part of only issuetype "Task(screen)" not "Defect(screen)". in such scenarios if i try to export my query using "Export(All fields)" function it fails to cast that object in defect(screen) because custom field is used only task(screen) of project "B". how do we ignore such cases? changing Global configurations for Issuetype & project works for other custom fields but couple of custom fields are shared with lot of projects and it is really difficult to change at the configuration level. is there any way we can ignore this through Script that i am using?
