GWT, navigate to page using POST request

Question

I want to navigate away from my GWT app using a POST request. If it was a GET I could just use Window.Location and if I didn't need it to be dynamic I could hardcode a Form and submit it. The FormPanel seems to be the answer for creating and submitting forms, but it does it asynchronously, and I want the user's browser to follow the form submit, navigating away from my app, rather than just displaying the results.

Anybody know how to do this in Google Web Toolkit?

Answer 1

Havn't done this myself but I think you should be able to create a FormPanel and then cast its element to FormElement and call submit on the FormElement.

FormPanel formPanel = new ...
FormElement form = FormElement.as(formPanel.getElement());
form.submit();

Ok, got it!

Passing null to the String contructor of the FormPanel says "replace the current page".

i.e. new FormPanel((String)null);
