Martin Tzvetanov Grigorov resolved WICKET-6854. ----------------------------------------------- Assignee: Martin Tzvetanov Grigorov Resolution: Cannot Reproduce Closing as "Cannot Reproduce". The behavior works just fine for me with latest 9.0.x. Tested it with wicket-examples module: {code:java} diff --git wicket-examples/src/main/java/org/apache/wicket/examples/echo/Echo.java wicket-examples/src/main/java/org/apache/wicket/examples/echo/Echo.java index bdb837c7cc..09a150d8b0 100644 --- wicket-examples/src/main/java/org/apache/wicket/examples/echo/Echo.java +++ wicket-examples/src/main/java/org/apache/wicket/examples/echo/Echo.java @@ -16,6 +16,8 @@ */ package org.apache.wicket.examples.echo; +import org.apache.wicket.ajax.AjaxRequestTarget; +import org.apache.wicket.ajax.form.OnChangeAjaxBehavior; import org.apache.wicket.examples.WicketExamplePage; import org.apache.wicket.markup.html.basic.Label; import org.apache.wicket.markup.html.form.Form; @@ -48,7 +50,12 @@ public class Echo extends WicketExamplePage // else with this form as the shared model is automatically updated // on form submits Form<?> form = new Form("form"); - form.add(new TextField<>("msgInput", messageModel)); + form.add(new TextField<>("msgInput", messageModel).add(new OnChangeAjaxBehavior() { + @Override + protected void onUpdate(final AjaxRequestTarget target) { + System.err.println("=== CHANGED : " + getFormComponent().getModelObject()); + } + })); add(form); {code} Tested it with Firefox 83 and Google Chrome 81.
