Yes, I'm using the form default setting (DefaultFormProcessing = true). But for form processing you have to use a submit button or a SubmitLink or you can call the form validate() method programmatic.
See also Wicket API Doc of Form: ( http://wicket.apache.org/apidocs/1.4/org/apache/wicket/markup/html/form/Form.html Wicket API Doc ) "/If you want you can call validate() to execute form validation, hasError() to find out whether validate() resulted in validation errors, and updateFormComponentModels() to update the models of nested form components./" the first two are working perfect, but not the programmatic way. Nevertheless I found a solution for my problem. I'm using a SubmitLink in my LinkTree component. For that I had to override the newLink() method of LinkTree. see also the thread: http://apache-wicket.1842946.n4.nabble.com/Using-SubmitLink-as-a-tree-node-tc3914407.html SubmitLink in BaseTree Thanks for your hints!
