When used "Statistic On Transtions Report" and selected "no" in "Display Column Filter" option, it works well. But when I selected "yes" in "Display Column Filter" option, it occurred the following error. I tried to remove some columns in my issue navigator and generated the report again. This time I selected "yes" and it works. I suppose this may be caused by some JIRA custom fields which your product doesn't support or may be there were too much columns in my issue navigator. But I cannot change my issue navigator each time I want to generate this report. Could you help us fix this?

Here error info?
