IssueFactory.getIssue（）创建了一个id == null的问题

Question

您好我使用adaptavist scriptrunner创建了一个创建子任务的小脚本：

ApplicationUser user   = // .. obtaining the user
MutableIssue parent = // .. obtaining parent issue
MutableIssue child  = issueFactory.getIssue()

// ... filling child with some data

// here the errors appear:
// workflow error
Issue subtask = issueManager.createIssueObject(user, child)
// null pointer
subTaskManager.createSubTaskIssueLink(parent, child, user)

我试图找出错误的原因，看起来我发现了问题所在： child.getId（）返回null。我错过了什么？ getIssue()应该返回没有ID的空白问题吗？

Jira版本7.1.7

Answer 1

这应该有效：

• 使用IssueService.validateSubtaskCreate验证输入参数。
• 使用上一个方法返回的validationResult来调用IssueService.create。
• 使用SubtaskManager.createSubtaskIssueLink链接父和子任务问题，就像您已经做的那样。

还有this related question on Atlassian Answers有一些示例代码。

Answer 2

MutableIssue child  = issueFactory.getIssue()
// issueFactory.getIssue(), returns an instance of MutableIssue, 
// that will be used to set issue data, here issue is not yet created
// in jira yet hence issue id and key will be null here
// ...

Issue subtask = issueManager.createIssueObject(user, child)
// issueManager.createIssueObject(user, child), creates the issue
// in the jira and after execution of this statement, you can retrieve
// issue id and issue key
