I have a question about menus in the new pages. When I have two almost identical pages, lets say Page 1 and Page 2
page1.vm:
Page 1
<form action="secure/admin/Action2.jspa" method="post" class="aui">
<!--some form fields-->
<button class="aui-button aui-button-primary">Goto Page2</button>
</form>
page2.vm:
page 2
Now I am trying to create configuration pages for a plugin. So I have placed a new item into the menu and that item links to /secure/admin/Action1.jspa, which displays page1. From page1, I submit a form with /secure/admin/Action2.jspa and display page2.
The question is, even though there is no content like
<meta content="admin" name="decorator" />
on either of the pages, they each display in a different way. Page 1 is displayed in the Addons menu with the sidebar and the plugin administration link highlighted.

But, when I go to page2 from this page, the sidebar menu disappears.
How do I get the sidebar back on page2?
