Hi

i need  script that copy date value from c

i try with below script but not worked and when execute transition (behind is script post function) error showed.

import java.util.*
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import static java.lang.Math.*
import java.sql.Timestamp
 
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def customField = customFieldManager.getCustomFieldObject("customfield_10408")
def customFieldtemp = customFieldManager.getCustomFieldObject("customfield_10500")

issue.setCustomFieldValue(customField, customFieldtemp)

error:

Error occurred while creating issue. This could be due to a plugin being incompatible with this version of JIRA. For more details please consult the logs, and see: http://confluence.atlassian.com/x/3McB com.atlassian.jira.issue.fields.ImmutableCustomField cannot be cast to java.util.Date
