[Zope-dev] manage_tabs

Hi. In my Zope product, I've got this; manage_options = SimpleItem.manage_options+( {'label':'Edit', 'action':'manage_main'}, ) If I view the management sceen of this product, I get four tabs (Undo, Ownership, Security and Edit). But If I click on "Edit", all tabs but the edit tab is removed. Why? My "Edit" dtml looks like this; <dtml-var manage_page_header> <dtml-var manage_tabs> <p class="form-help"> This is the edit form. </p> <dtml-var manage_page_footer> Thanks, /Magnus
