Hi Frank,

Go for it. Note I would recommend looking into seeing if f:partial would be an easier route than messing with f:ajax directly.

Thanks!

Kind regards,
Manfred Riem

Subject: [faces-dev] Partial Partial Updates

Hi,


Within Chapter 3 of the Enterprise JSF document, available via:
https://github.com/e-Contract/enterprise-jsf
I muse on how to apply different rendering techniques using JSF.

When looking at partial updates, right now it always happens at a component granularity level.
However, with a little tweaking the Faces runtime can be used to partially update selected sections of a component instead of the component as a whole.
The client-side Faces Javascript does not mind what it is actually updating, it just executes the received XML update instructions.
Under section 3.4 Partial Partial Updates, I implemented this idea using a custom PartialResponseWriter.
For some components, this has the potential to reduce the required update data set drastically.


Maybe the Faces API could support such "partial partial updates" directly?


Kind Regards,
Frank.
