Hi, 
I cannot make a ticket in the JIRACLOUD queue, so I am leaving it here (please transfer the ticket if needed). 
We are using Atlassien Cloud since like a year (a company hosted instance before) and since forever there is one problem: the "Resolution" field is not editable. So if once a ticket was closed (an the "Resolution" field was set) and than reopened, the ticket Id will be showed as stricken through in any dashboard (as it would be still closed, but it is not). So it would be good to either: 
1. make that field editable so it can be reset to null or

2. do not check the "Resolution" filed in Dashboards to signal if the ticket is open or not and rather check the status of the ticket for this purpose
