[jifty-devel] state variable craziness

[Chia-liang Kao]

Hi,

I've just committed a test app for the SinglePage plugin, which exploits
some bugs in variable and region variable handling.  the test app
consists of a page with a select dropdown, submit the value to a region
that it replaces with, which contains a createuser action and a redirect
action that comes back to the first page.  here's the transcibed dialog:

---------- client sends onclick replace with explicit args
{"path":"/__jifty/webservices/xml","actions":{},"fragments":{"__page":{"name":"__page","path":"/page2","args":{"":"Next","foo":"4"},"parent":null}},"variables":{"region-__page":"/page2","region-__page.":"Next","region-__page.foo":"4"},"continuation":{}}
---------- server returns an action form with serialized variables
<form method="post" action="/" enctype="multipart/form-data" >
<input type="hidden" name="J:V-region-__page" value="/page2" />
<input type="hidden" name="J:V-region-__page.foo" value="4" />
---------- client submits action
{"path":"/__jifty/webservices/xml","actions":{"create_user":{"moniker":"create_user","class":"TestApp::Plugin::SinglePage::Action::CreateUser","fields":{"name":{"value":"4"},"email":{"value":"orzorz at of"},"email_confirmed":{"fallback":"0"}}},"auto-e04fb2080eaf81eb7483ef274bea95cd-1":{"moniker":"auto-e04fb2080eaf81eb7483ef274bea95cd-1","class":"Jifty::Action::Redirect","fields":{"url":{"fallback":"/index.html"}}}},"fragments":{"__page":{"name":"__page","path":"/page2","args":{"":"Next","foo":"4"},"parent":null}},

"variables":{"region-__page":"/page2","region-__page.":"Next","region-__page.foo":"4"},"continuation":{}}
---------- action taken, redirect to first page
<form method="post" action="/page2" enctype="multipart/form-data" >
<input type="hidden" name="J:V-region-__page.foo" value="4" />
---------- all gone crazy
{"path":"/__jifty/webservices/xml","actions":{},"fragments":{"__page":{"name":"__page","path":"/page2","args":{"":"Next","foo":"1","J:V-region-__page.foo":"4","J:V-region-__page.foo=4":"Next"},"parent":null}},
"variables":{"region-__page":"/page2","region-__page.":"Next","region-__page.foo":"1","region-__page.J:V-region-__page.foo":"4","region-__page.J:V-region-__page.foo=4":"Next"},"continuation":{}}

Can someone familiar with the use of state variable clarify?  is it
supposed to hold up all region's varible we've ever seen as fully
qualified form?

Cheers,
