[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-3033) make s:graphicImage work with s:cache

[Daniel Roth (JIRA)]

Daniel Roth updated JBSEAM-3033:
--------------------------------

    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>

> 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.
