Hi guys.
This is not a MyFaces related problem, but a JSF related problem. Maybe
someone here could help me.
I'm writing a set of components for a new web application based on JSF.
Among requisites there is the need to build some forms in a dynamic way:
the application will sell products that will change in the future, and
the request from our committee is that (only for some product) forms are
to be auto-generated from a xml structure (or something similar) that
can be built using product info stored into the database.
Now my problem is this: I have created a jsf components that reads the
xml and creates new inputs components using validations and conversions
directly from the passed informations (using Shale and its validator
tags I can add javascript validation too!). It's great, but I don't
think it's the right approach to the problem, because I'm creating new
components dynamically during the rendering phase of my component and I
have to make them not transient to allow the lifecycle to be applied to
my fresh created components. So, when the page is reloaded for some
reason, I get a duplicate id error, 'cause I'm adding components in the
view that I've already added before. I can check in some way if I have
to add or not my new inputs, but for reasons I can't explain, it is not
always possible for me to do this check.
Where I'm wrong with this problem? Is my solution totally wrong or is
there a way to safely add not transient components to my view without
the duplicate id problem?
Thanks.
Regards,
Pierpaolo
