Get files, attached from JSD Portal

[Saida Jafarova]

Hi there, 

I need a listener, which will clone all attachments from a Service Desk to a Software project. 

I wrote the one, but during testing we have found that the listener doesnt work if attachment is added in comment from the customer portal. 

I have configured the custom script listener on Issue Commented, Issue Updated Event, but

event.getChangeLog() returns nothing 

event.getComment() returns com.atlassian.jira.issue.comments.CommentImpl, 

and there is no any methods in CommentImpl to get the file attached. 

Also, system doesnt fire Issue Updated event when adds attached files to the issue. 

How can I solve this issue for JIRA Service Desk 3.10.0?

ScriptRunner version:    5.3.5

Thank you
