While testing the changes in the content server, Juan and myself detected that
one of the css included in the page, and all the images, have the same name for every decorator.
This produces strange interactions with caching whenever there are fragments
using two different layout decorations in the same page, or the user switches pages.
The icons and styles are taken apparently randomly from both stylesheets, which
plays havoc with the decoration.
It looks like a solution for this would be to have the decoration name in the resource,
now: content/images/edit.gif -> content/THEME/images/edit.gif
now: content/css/styles.css and content/THEME/css/styles.css -> content/THEME/css/layout-styles.css and content/THEME/css/portlet-styles.css
Not sure if it was a bug or intended in the last batch of changes by Scott, so I just post here for clarification.
