Subject: Providing component design-time meta data

Hi All,

I have had an email exchange with Matthias about JSF, MyFaces and ADF 
Faces and what level of design time support faces component authors 
would, or could, expect from tools vendors such as (in my case) Oracle's


A couple of months back we (the Oracle ADF Faces team) posted a proposal

for design-time metadata for JSF at the JSFCentral website 

Matthias thought it would be a good idea if I sent an email to this 
mailing list asking for feedback on the proposal.

One of the concerns that we have is the lack of information provided by 
the JSF spec that defines what syntax to use for associating additional 
metadata with faces components. This lack of information can force tools

vendors to come up with their own syntax to support additional metadata 
for custom components, which would force component authors to have to 
deal with different solutions for different IDEs.  If there is a 
standard in this area, component authors would be able to provide 
metadata in one format that will work in all tools, and the end user 
will be in the ideal situation of being able to pick the tool they want 
to use independently from the component set that best meets their needs.

The goal would be to have a good and productive discussion about this 
topic/proposal and try to come up with a solution that all parties 
involved (component authors, tools vendors etc...) could agree upon, and

then put it in front of the EG as a proposal from the community to 
enhance JSF. As one of the leading JSF organizations comments and 
contributions from MyFaces to this proposal are greatly appreciated.

Matthias please feel free to correct me if I interpret your email
