Hi.
Has anyone integrated Weblets into MyFaces via the AddResource?
I'm writing my own components that rely on some js/css. Weblets seem to be a
right thing to manage resources. Seems much easier to use and configure than
MyFaces analogs.
At the same time I consider taking advantage of positioning resources with
AddResource. That is, I'd like to add a script once to the header even if it's
used 200 times in a page.
A custom AddResource implementation could adapt Weblets to manage resources.
Another problem with AddResource is AJAXified components. For instance, with
ajax4jsf.
Current implementation of (say) StreamingAddResource uses a very tricky approach
to manage stylesheets:
1. You have to use this with t:documentHead which renders a link to
pseudo-stylesheet. This links carries an unique id of the requst, for instance:
123/header.css.
2. When rendering the components, they may add some stylesheets to the header.
These are gathered in some kind of a map associated with the request id (123).
3. After the rendered html is delivered to the client, the client requests the
123/header.css.
4. This is intercepte by MyFaces which in its turn create a header.css with all
the
@import url("my-style.css");
for styles that were added by the components.
Scripts are currently managed a bit differently, but I think this is also gonna
change.
In my opinion, this is rather a tricky way to shut yourself in the head.
Why not simply pre-render body in a buffer (gathering the styles/scripts for the
header or whatever), and then happily render the head with all the gathered
resources? A combination of document/head/body components could easily do it.
You only need a some tens of kbs buffer to pre-render the body...
So my question before I start implementing something myself is if anyone has
done something in this direction, are there alternative AddResource
implementations and so on.
Are these issues adressed in JSF 1.2 somehow?
Bye.
