I had form.hidden.fields() but not form.latest.id, now corrected
(form.record.id doesn't work for me).
I also added the T2 field I need:
<input type="hidden" name="modified_on__original"
value="{{=form.latest.modified_on}}" />
I also added id & modified_on to my FORM line:
form=FORM(INPUT(_name="id",_value=layer.id),INPUT
(_name="modified_on",_value=layer.modified_on),INPUT
(_name="name",_value=layer.name),INPUT
(_name="description",_value=layer.description),SELECT
(_name="type",_value=layer.type),SELECT
(_name="subtype",_value=subtype),INPUT
(_name="priority",_value=layer.priority),INPUT
(_name="enabled",_value=layer.enabled),INPUT(_type="submit",_value=T
("Save")))
I also converted all my form fields from:
<td><input name="name" type="text" value="{{=layer.name}}" /></td>
to:
<td><input name="name" type="text" value="{{=form.latest.name}}" /></
td>
Still nothing seem to link together the 'form' with the manual HTML :/
What else is needed in this scenario?

I have a global error div underneath the form:
{{if form.errors:}}<div class="error">{{=form.errors}}</div>{{pass}}
I've added specific ones underneath each field (which I'll try to
clean the output on later):
{{if form.errors.name:}}<div class="error">{{=form.errors.name}}</div>
{{pass}}
None of these get triggered, though (although the global one did when
using SQLFORM instead of FORM)

So form_builder is something I only see described here:
http://groups.google.com/group/web2py/browse_thread/thread/582863bdd056bd7b/4212aa3f99eb7c31?lnk=raot&fwc=1
Doesn't seem to be part of the std code.
I'll give it a try.

I'm not sure what 'no knowledge of the db means'
The validation defined in the model is sufficient for validation,
right? I don't need to redefine in my form? (unless I choose to add
more restrictions)
I try to do the db updates manually within 'if form.accepts', e.g.
db(db['gis_layer_%s' % type_new].layer==t2.id).update
(type=form.vars.subtype)
But it doesn't work.
I tried giving the form a matching name - within the HTML view, within
the FORM & even in the form.accepts
(as suggested here:
http://groups.google.com/group/web2py/browse_thread/thread/df59525001ebedc1/656128708948019e?lnk=gst&q=formname%3D%22myform%22#656128708948019e)
Nothing seems to work.
My form values are kept, I get my 'Form accepted' message, but the DB
remains stubbornly un-updated :/
