According to what you propose, I have added in the onSubmit() method of my
form class, the following method :
public void onSubmit() {
// Populate list using search Criteria
populateList((RequestModel) this.getModelObject());
}
populateList calls a service returning from my DB the records. The result (=
records) are put in a LoadableDetachableModel which is used by the DataView
to display the result in a DataView.
private void populateList(RequestModel requestModel) {
// Generate Data View to display requests in a table
final DataView dataView = new DataView("requestList", new
RequestProvider(requestModel)) {
public void populateItem(final Item item) {
final Request request = (Request) item.getModelObject();
....
Unfortunately, when onSubmit (of my form) is called, Wicket generates the
following error :
WicketMessage: Method onFormSubmitted of interface
org.apache.wicket.markup.html.form.IFormSubmitListener targeted at component
[MarkupContainer [Component id = requestForm]] threw an exception
Root cause:
java.lang.IllegalArgumentException: A child with id 'requestList' already
exists:
How can I avoid this ?
