I have created a filter with criteria: "Assigned to: specific-group: A"

After that I have created a two-dimensional portlet: columns had asignees, rows had priorities.

When clicking on the name of assignee, I get back a list of issues assigned to group, NOT THE USER since the query built looks like this:

http://jira/secure/IssueNavigator.jspa?...&assigneeSelect=specificgroup&assignee=XXXX&...&assigneeSelect=specificuser&assignee=YYY

instead of:

http://jira/secure/IssueNavigator.jspa?...&assigneeSelect=specificuser&assignee=YYY

better yet, issue navigator should parse the string and take the LAST not the first parameter, something like:

String[] vals = request.getParameterValues("assignee");
String assignee = vals[vals.length-1];
