ClassCastException when using the "Show Empty Rows" option

[Nicolas Zastavni]

When trying to use the "Show Empty Rows" option to show all jiras in epics related to a given filter (not only the one for which there are encoded hours), the page redirect to a 500 response.

In the log, the following error is present:

Hi there, I'm getting the same error with Show Empty Rows flag set (Project Pivot report). I do not remember my original version, but I found this issue and upgraded to 3.0.5.3 (Jira 7.1.1) but the error is still there.

Thanks

Hi Marco,

I can't seem reproduce it. Could you please provide screenshot for gadget or report configuration that causes the problem?

Thank you.

[Marco Baldelli]

Hi Andriy, I currently don't have access to the instance so I can't send you screenshots. Scenario is very simple: I'm using Project Pivot Report: if I don't set any field but that one, it is ok (but it is a bit weird, because I can only see a few users). Then I configured it again adding a project, and it breaks. The strange behaviour I noticed later is that if I create the same report from gadget I can see it correctly even if I set Show Empty Rows to true, and then if I click "Details" the plugin will bring me to the Project Pivot Report page and everything seems to work.

Any idea?
