Re : Re : Re : [Zope3-Users] formlib problem
Thanks Jim,
I now get the page back with the right data. I now have to figure out how to
have the actions work.
I guess I'll have to ajaxify my page in order to pass the data and have the
form do it's work.
I'll let you know if I encounter further problems or if it works (hopefully).

Actually, you are using a page template.
Calling ItemsForm() invokes the render() method of
zope.formlib.form.FormBase, which uses pageform.pt in the zope.formlib
folder by default. This is where title_or_id is requested.
You may wish to set a different template for your ItemsForm class.
Have you tried subclassing form.SubPageEditForm instead of form.EditForm?

Re: FW: Re : Re : [Zope3-Users] formlib problem
Stéphane, i'm working on what sounds to be a pretty much identical issue currently... i'm attempting to use formlib and jsonserver. i've been throwing around a number of possible solutions, but none that i'm comfortable with so far. i agree, i don't know how to access my form.Form class programmatically, but i don't want to sacrifice all the utility provided me by formlib (errors, checking of invariants, etc, etc). i've considered having my exposed json-rpc methods pull in the params explicitly, and then wrap them back up into formlib-style data (if it's possible, i haven't had a chance to try yet), and then use the handleSubmit and applyChanges logic out of formlib directly. but i'm not happy with that solution. i would like to find a way to build my forms agnostic of how they're to be used, and associate jsonrpc:view's to a particular content area that can access the forms i've displayed. i've been really happy with the ability to build formlib forms into viewlets, and use them where/how i want... but if that keeps them from being ajax-y accessible, it will present a significant hurdle :\ if anyone has any suggestions, or has solved this kind of problem before, i'd really appreciate pointers. if i stumble across anything that seems useful, i'll post it back out.

Re : Re : [Zope3-Users] formlib problem
Hi, when I use formlib the traditional way (registering the page via ZCML, going to it via the ZMI), everything works fine. The problem is I can't access it programatically. The thing I try to do is : - call a method via JSON RPC (by the way jsonserver is great ;-)) - in this method I get my object (through sqlos, which is nice too ;-)) and then call the formlib class to render my page in html - send back the html which is used to update my page. Has anyone tried to use formlib this way, I really need to use AJAX and it seems that I can't have both working together, I must be missing something.
