Martin Grigorov commented on WICKET-5781:
-----------------------------------------
I don't see how Wicket 1.4 would work if the ModalWindow uses a Page.
Because in this case the ModalWindow creates an iframe for the page content. So
the JavaScript logic in wicket-ajax.js cannot find 'inNnameField' in the
current (top) document.
For ModalWindow I'd suggest to use OnDomReadyHeaderItem that is contributed by
the ModalWindow's page/panel. Because it will run in the correct context.

> Key: WICKET-5781
> URL: https://issues.apache.org/jira/browse/WICKET-5781
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.18.0
> Environment: Windows 7 64 bit, Tomcat 7, Java 7
> Reporter: Mark Walter
>
> I am using the following code to open a modal window and set the focus to the
> nameField:
> AjaxButton btn = new AjaxButton("btnNew") {
> private static final long serialVersionUID = 1L;
>
> @Override
> protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
> ModalWindow modalNewDefinition= new ModalWindow("mymodal");
> NewDefinitionPanel p = new NewDefinitionPanel( ...);
> modalNewDefinition.setContent(p);
> modalNewDefinition.show(target);
> target.focusComponent(p.getNameField());
> }
> }
> AjaxRequestTarget#.focusComponent works fine with Wicket 1.4 but ist has no
> effect with Wicket 6.18.
> WICKET AJAX DEBUG shows:
> ....
> INFO: returned focused element: [object HTMLInputElement]
> INFO: returned focused element: [object HTMLInputElement]
> INFO: focus set on inNnameField from server side
> INFO: Response processed successfully.
> INFO: Calling focus on inNnameField
> The information "INFO: focus set on inNnameField" is however missing and the
> focus is not set.
