Hi!
Created jira issue at https://issues.apache.org/jira/browse/WICKET-3166
2010/11/12 Martin Makundi <martin.maku...@koodaripalvelut.com>:
> Hi!
>
> I have a page with two panels:
>
> page.add(panel1);
> page.add(panel2);
>
> in some situations panel1 is not visible.
>
> However, a form submit event will visit all formcomponents of panel1 via:
>
> at
> org.apache.wicket.markup.html.form.FormComponent.visitFormComponentsPostOrder(FormComponent.java:400)
> at
> org.apache.wicket.markup.html.form.Form.visitFormComponentsPostOrder(Form.java:1209)
> at org.apache.wicket.markup.html.form.Form.inputChanged(Form.java:1403)
> at
> org.apache.wicket.markup.html.form.Form.onFormSubmitted(Form.java:865)
>
> This results in a crash because panel1 components are not prepared to
> be invoked via isvisible when the panel itself is not visible.
>
> I wonder if the component.isVisibleInHierarchy could be changed as
> follows, to first check parent visibility:
>
> public final boolean isVisibleInHierarchy()
> {
> Component component = this;
> while (component != null)
> {
> Component componentParent = component.getParent();
>
> if (((componentParent == null) ||
> componentParent.isVisibleInHierarchy()) &&
> component.determineVisibility())
> {
> component = componentParent;
> }
> else
> {
> return false;
> }
> }
> return true;
> }
>
> Similar change could/should maybe be possible also for isEnabledInHierarchy ?
>
> Comments?
