make s:graphicImage work with s:cache

Key: JBSEAM-3033
URL: http://jira.jboss.com/jira/browse/JBSEAM-3033
Project: Seam
Issue Type: Feature Request
Components: JSF Controls, Performance and Scalability
Affects Versions: 2.0.2.GA
Environment: All
Reporter: Daniel Roth
Priority: Minor
Fix For: The future
s:graphicImage with its transformations is a great tag to use for user uploaded images.
However, having a couple of images on the same page makes the page a bit slow to load due
to transformations. One can quite easy make the transformations oneself and cache them,
however a nicer solution would be if s:graphicImage could be used inside s:cache tags.

-----------------------------------------
And how is that supposed to work? s:cache is global, so you couldn't even cache them
in the users session (until it is destroyed, which would still be a very bad idea).

-------------------------------------
It is a feature request, the workings I guess are up to Assignee to figure out. Maybe
<s:graphicImage cache="dimension"> is another approach.
In my use case, responsiveness is a major concern. Pre-scaling(on startup/upload) and
storing all images in-memory to get rid of the transformation cost works like a charm.
However, I think it would be better to have that kind of ui code removed from the business
code. Being able to cache the images with jsf tags would therefore be really nice.

Attachment: cache.patch
This is one way of doing it which works well. The developer controls cacheKey for each
image (so that he/she may invalidate them when necessary) and may also set a flag for
removing a key.
The cache used is the one provided by the CacheProvider, which the developer may configure
as he/she likes.
Using this patch on pages with lots of images ("webshop") makes the app
significally faster.
Example
<s:graphicImage value="#{bean.file}" cache="true"
cacheKey="#{bean.file.id}-size0.5"
invalidate="#{bean.file.dirty}">
<s:transformImageSize factor="0.5" />
</s:graphicImage>
