I have something I do not understand in Wicket. I created an AJAX Button with an override method onSubmit() linked with my HTML page. Once I press the button the method is not call.

Here the JAVA code:

  AjaxButton savebutton = (AjaxButton) new AjaxButton("save_ext", form) {

        @Override
        protected void onError(AjaxRequestTarget target, Form<?> form) {
            super.onError(target, form); //To change body of generated methods, choose Tools | Templates.
            System.out.println("save button ajax error");
        }

        @Override
        public void onSubmit(AjaxRequestTarget target, Form<?> form) {

             System.out.println("save form");
    }.setOutputMarkupId(true);

form.add(savebutton);

Here the HTML:

<button type="submit" value="save" wicket:id="save_ext" class="btn btn-success" id="buttonSave_ext" onclick="saveFunction()">Save</button>

Do you have an idea how to solve the problem.

Thanks

  • I have the same issue now, if you remove `onclick` in the button tag. Does it work? But mine does not have `onclick` but still I cannot reach `onSubmit()`. It sends requests when I click the button, but never reaches `onSubmit()` code. – Borgy Manotoy Dec 07 '22 at 02:43
  • Oh this thread is too old. Sorry, my project is using old wicket 6.3. I find it weird since I do not get any errors (dev tools console, it sends request when I click button submit), but I cannot hit `onSubmit()`. Too bad debug mode does not work on my IDE now. – Borgy Manotoy Dec 07 '22 at 02:45

Check in DevTools/Firebug whether there is an Ajax request made by clicking on the button. I see you have a "onclick" function in your markup. If it returns false then the other event listeners won't be executed, i.e. Wicket's click listener won't fire the Ajax call to notify the server side.

  • I checked, I have IBehaviourListener. When I press the button, I do not see AjaxRequest but my javascript function work and returns true. How can I have an Ajax Request? – user3774233 Apr 30 '15 at 09:36
  • First try by removing your "onclick". If this doesn't help then put a breakpoint at https://github.com/apache/wicket/blob/wicket-6.x/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js#L554 and see where it goes. Maybe some precondition?! – martin-g Apr 30 '15 at 13:17
  • I tried to remove onclick tag and still the same problem. I checked on Firebug I receive only one GET IBehaviourListener and no POST. What does it mean? Should I receive a POST? – user3774233 Apr 30 '15 at 13:49
