Oh, in this case the approach I suggested does not work, I
think...sorry but I didn't get "page flow" logic properly.
Then your approach of a submit handler will be better.
MaybAs an alternativeif you don't strictly need a form for what you'r
doing you can define a GWT RPC method that contains the parameters you
need to redirect properly or update your GUI.
Something like this:
//RPC interface, synchronous version
public String submit(SubmitWrapper content); //SubmitWrapper class
contains what you want to submit
//invocation
SubmitWrapper content = .....//build
submitService.submit(content, new AsyncCallback<String>(){
onSuccess(String redirectURL){
Window.open(redirectURL, "_self", null);
}
onFailure(Throwable caught){ //handle}
});
Whether to use an handler or define your RPC depends on your needs (I
don't know struts so much...), yet it's another alternative you can
consider if you're still designing your interface.
I can suggest you to join the GWT discussion group here:
