Alex,Thanks a lot for help!! So it is known feature, Wow! Then additional question How can I produce "fictive" copy? That means, if I really want to copy only into 2-d parameter, how can I "simulate" copy into 1-st parameter and really leave it untouched? Is there preferable and simple or any tricky but generic approach? Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3997889#...
