Can't get issue key in context provider via jiraHelper

[zhen zhang]

Hi Everyone,
I am debugging one customized plugin, which was worked fine in JIRA 5.1.3, but not work in JIRA 6.4.1. The piece of code is below. the method-1 always return null, method-2 sometimes return correct issue key, sometimes return null. Does anyone have idea on this issue? thanks in advance!

Method -1:
String issueKey = jiraHelper.getRequest().getParameter("key");  //works fine for JIRA 5.1.3, but not ok for 6.4.1 

Method-2:
Map map = jiraHelper.getContextParams(); 
IssueImpl issueImpl = (IssueImpl)map.get("issue");
String issueKey = issueImpl.getKey(); //sometimes getKey() return null.

it seems that method-2 's behavior is normal, I add exception handling solve this problem.
