force client to use GET method
Hi
How do I tell the client to use a GET method instead of POST?
The problem is, the client is sending the form from a previous page
in a POST request, causing a double submission.

Sorry, this seemed like two different ways that may solve the same problem.
anyway, problem solved. Thanks for your great support!

store a flag in the form that change to true when the form is submitted.
then, in onsubmit, check "if(myflag) { return;}"
should work... ugly but should work

Can you give more details on what you mean by submitting the form of the
previous page again?
Is this:
1 - the user is clicking the submit button, and then clicking again before
the page every changes?
2 - the form is being submitted, and the user is doing refresh / etc / to
resubmit?
Number two is handled by default by Wicket using the redirect to buffer
strategy, unless you have modified settings otherwise.

Tell people to use a less stupid browser than IE? (Which is the one with
that behavior if memory serves)? :)
Real solution: Use a "hidden" token that you use to check whether the
particular form already has been posted, and in that case just skip the
form processing and work on the already processed object, something like
this in onSubmit():
// Map<String, DataObject> objectmap...
// Form<DataObject>
String tokenvalue = form.get("token");
DataObject obj = objectmap.get(tokenvalue);
if (obj == null) {
// Not already handled
obj = this.getModelObject();
// TODO Persist or whatever
// Put in map
objectmap.put(tokenvalue, obj);
}
// TODO Operate on obj
Instead of this thrown-together example using an objectmap (which will
get filled with "garbage"), use the session.

Ok.. that didn't stop the client from submitting the form of the previous
page again.
Any other solutions to preventing double submissions?
