A bug in params transfer ? I call this url http://localhost:8080/book/seq/21/21?act=55689c4fe4b02318d27d2d22&act=55689c4fe4b02318d27d2d22 There is a list of 2 act as parameters. In the "seq" action, for params.act, I get a List of 2 elements as wanted. But if I call include to get the content of another action, in the params, i get a list of 3 elements !?! The first one is a String with the type => [Ljava.lang.String;@54e75502, the 2 others are the wanted ones. I attach some screenshots of my debugger to see this weird thing
