First, let me restate the intent of the<br> feature.<br><br> FEATURE SHORT DESCRIPTION:<br> ==========================<br><br> Let JSF2 resources refer to other resources in a way that the browser<br> can make GET requests to load them via the ResourceHandler.<br><br> RATIONALE for FEATURE:<br> ======================<br><br> CSS files may refer to other files using the following syntax<br><br> url( some URL )<br><br> The url() element may appear in several places in a CSS file, most<br> commonly to the right of @import, as in<br><br> @import url(layout.css)<br> @import url(typography.css)<br> @import url(colorAndMedia.css)<br><br> Unfortunately, this doesn't "just work" when the CSS file in question is<br> in a JSF resource library, for obvious reasons.<br><br> The solution we chose was to allow EL expressions in CSS files. That<br> way, you could say this in your css file:<br><br> @import url(#{resource['this:layout.css']})<br> @import url(#{resource['this:typography.css']})<br> @import url(#{resource['this:colorAndMedia.css']})<br><br> and when the file actually gets served up it would look like:<br><br> @import url(/jsf-ezcomp02/javax.faces.resource/layout.css.jsf?ln=ezcomp);<br> @import url(/jsf-ezcomp02/javax.faces.resource/typography.css.jsf?ln=ezcomp);<br> @import url(/jsf-ezcomp02/javax.faces.resource/colorAndMedia.css.jsf?ln=ezcomp);<br><br> PROBLEM 1. This behavior should have been specified in the javadocs for<br> Resource.getInputStream(). I've added this to the ChangeLog.<br><br> PROBLEM 2. JavaScript resources have the same problem; they can refer<br> to other javascript files and the browser needs to know how to fetch<br> them. We employed the same solution: put EL in there and it gets<br> evaluated on the way out.<br><br> Unfortunately, the prototype JavaScript library uses #{} to mean<br> something important.<br><br> SUGGESTED SOLUTION to PROBLEM 2.<br><br> Let's assume PROBLEM 1 didn't exist. I suggest we modify the spec for<br> getInputStream() to say that all resources EXCEPT JavaScript resources,<br> must do the EL evaluation on the way out. We need some way for users to<br> enable the feature for JavaScript resources because, let's face it, not<br> everyone uses prototype. Ryan and I suggest we adopt a protocol that<br> says, "if the resource name ends in '-el' we always turn on the EL<br> evaluation on the way out".<br><br> Thoughts?<br><br> Ed<br><font color="#888888"><br> --<br> | <a href="mailto:ed.burns@sun.com">ed.burns@sun.com</a> | office: 408 884 9519 OR x31640<br> | homepage: | <a href="http://ridingthecrest.com/" target="_blank">http://ridingthecrest.com/</a><br></font></blockquote></div><br> </html>
