Here's how to do what you asked. That's not what you want, but it's
what you asked for: :)
<edit-page>
<form:>
<submit: replace>
<transition-buttons/>
</submit:>
</form:>
</edit-page>
What you want to do.
1) add params to your save transition. Hobo automatically makes a
page with the form for lifecycle actions
2) link to it from your show-page (or wherever)
<a action="save">Edit Foo</a>
3) turn off the non-lifecycle edit link in your controller.
auto_actions :all, :except => [:edit]
If you're on the latest version (gem "hobo", :git =>
"git://github.com/tablatom/hobo", :branch => "1-3-stable") in your
Gemfile, you can do:
<show-page>
<after-field-list:>
<transition-button transition="alter"/>
<transition-link transition="save">Edit Foo</transition-link>
<transition-button transition="delete"/>
<transition-button transition="submit"/>
</after-field-list:>
</show-page>
