[richfaces-issues] [JBoss JIRA] (RF-12537) Resource Ordering -aware HeadRenderer

[Lukáš Fryč (JIRA)]

    [ https://issues.jboss.org/browse/RF-12537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12727191#comment-12727191 ] 

Lukáš Fryč commented on RF-12537:
---------------------------------

Actually, as Adrian pointed out, ECSS and reslibs are supported, they are added to the {{others}} collection of resources.

But that way priority and reslib expansion wouldn't be processed.
This would lead into pseudo-optimal state.

> The order of resources rendered in a head is currently un-managed and can cause resource ordering issues. (Which may be partially fixed by using different placement of h:outputScript tags).
> Furthermore a performance of application perceived by user might be significantly enhanced when ordering head resources correctly (see Yahoo recommendations).
> The proposal of {{HeadRenderer}} by Adrian Mitev:
> https://gist.github.com/3899465
> ----
> This proposal has several drawbacks:
> * doesn't count with mime-types, depends on resource names (Resource provided by ResourceHandler may be used here to obtain mime-type)
> * resource names stored in attribute "name" are not part of JSF spec (afaik) and thus implementation-dependent
> * the implementation does not count with resource library notion (.reslib)
> * ECSS is unsupported, but it can be simply changed with using ResourceHandler as described above
> Other than that the proposed solution seems like enough generic.
