[jira] [Resolved] (WICKET-4056) Invisible Form creates empty Page

["Igor Vaynberg (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/WICKET-4056?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Igor Vaynberg resolved WICKET-4056.
-----------------------------------

    Resolution: Invalid
      Assignee: Igor Vaynberg

in this code
{code}
MarkupContainer form = add(new Form("loginForm"){...}); form.setVisible(false);
{code}
the variable form is assigned the page instance, not the form. because component's add method is chained, it returns the component that add is called on, not the added components.

since form=page and you call page.setvisible(false) you get an empty document.
