Hyperlink reference expression

Hi,

Please if someone can help, I want to create a link from a mainreport to an other report using the hyperlink. I use a text field and right-click Hyperlink. I choose reportExecution, but what then?

Hyperlink reference expression like "http://localhost:8080/jasperserver-pro/flow.html?_flowId=viewReportFlow&standAlone=true&_flowId=viewReportFlow&ParentFolderUri=%2Fpublic&reportUnit=%2Fpublic%2FanotherReport" or "/anotherReport" ? Neither works. Do I have to set anything else? I also trie adding parameter "_report" with above values.  

What do I have to set in the hyperlink box. Right know I do not want any parameters.

Thanks in advance!
