Subject [jira] [Commented] (MYFACES-3740) ResourceResolver "this" identifier applies for contracts too in JSF 2.2
Date Wed, 26 Jun 2013 19:25:19 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-3740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13694182#comment-13694182
] 

Leonardo Uribe commented on MYFACES-3740:
-----------------------------------------

The problem with this issue is that to resolve "this" identifier it is necessary to setup
the context. For example, if a css resource is being served, the resulting EL expressions
that are evaluated must take the context into account. If the file is a simple template, "this"
should refer to the current facelet template, but that's tricky because if the EL expression
is evaluated outside facelets control, the reference is lost.

> Doing some reviews in the code, I found these lines in JSF 2.2 section 5.6.2.5 :
> getValue()
> "... If property contains a single colon character ‘:’, treat the content before
the ‘:’ as the libraryName and the content after the ‘:’ as the resourceName and pass
both to ResourceHandler.createResource(
> resourceName, libraryName). If the value of libraryName is the literal string “this”
(without the quotes), discover the library name of the current resource (or the contract name
of the current resource, the two
> are mutually exclusive) and replace “this” with that library name (or contract name)
before calling
> ResourceHandler.createResource(). In the case of resource library contracts, libraryName
will actually be the contract name. If property contains more than one colon character ‘:’,
throw a localized
> ELException, including property ..."
> In JSF 2.0, "this" was used when el expression where inside composite components, but
in this case "this" refers to the contract itself.
