Dynamic generation of CForms

[Mattom <ma...@gmx.at>]

Hi all !

After mastering my custom generator problems I am facing CForms now.

What I want to achieve is:
o) query my db access objects for metadata - this will give me xml trees 
describing the tree structure of my db data
o) transform this metadata xml to a CForms definition
o) render the form

I had a look at the form samples and found some useful info in the form1 
example.

This example does almost everything the way I'd like to do it, calling a 
custom action that generates the form instance, and do the rendering in 
the pipeline. All I have to do, is to replace the "static" filebased 
generation of the form instance by my dynamically generated form definition.

Now I am not sure what the approach would be, should I

o) Stay with a custom action, query my db object for the xml metadata 
and do a xslt transformation in the action to get my form instance
or
o) Do a pipeline  approach, with a generator getting xml from my db 
layer, then a pipeline xslt transformation

Thank you,
Tom

Certainly the best way - and make sure to make this pipeline's 
intermediate stages available (via sitemap views for example) for 
debugging.

with that approach you will heavily miss up concerns.

that seems to be the far more cleaner design.
