Hi Carl-Eric,

WICKET-4107 was specifically about preventing GET request on stateless forms. Why not do something similar for Ajax behaviors?


Have fun

Hi,

I've just encountered an interesting oddity. For a normal form submission, there is Form#onMethodMismatch where I can decide what should happen if somebody calls the form's URL with a GET request rather than the usual POST. At least in 6.x and 7.x this is called from onFormSubmitted() - but not from onFormSubmitted(submitter).

The result is that for forms that have an ajax button and thus a valid submitter, I can't stop somebody building a GET request and firing that against the button's URL. Theoretically I could override AjaxFormSubmitBehavior's onEvent method, but that doesn't work for ajax buttons, which build their own AjaxFormSubmitBehavior.

On one of my current projects the customer is quite security-minded and would like the application to block these GET requests. My question is: Is it intentional that only the regular onFormSubmitted() method checks this? If yes, I'd like to know the reasoning please. If not, I'm going to write a patch to fix this.

Or maybe I'm missing something and am going the wrong way entirely. In that case, let me know please.

Carl-Eric
