Hello Todd, Thanks for your quick answer.
Yes I know I can do that, but that way, everytime that I want to
change the menu, I have to change the code, and thats what I want to
avoid.
I really want to do that because I'm starting a project, and I know
(by experience) that the menu will have a lot of changes.
But do you think that I souldn't use the client side solutions? Like
the "gwt-ent" and "gwt reflection" libraries? What is the problem with
them?
My last solution is to generate all the menu from the XML, and
interpret the actions with a client side function. Example, every
action like doAction("Home"). This solution is very likely yours, and
I get a semi-dynamic Menu.
Regards.
