Hi I think it is a bug in JSF 2.2 spec. The behavior for ScopedAttributeELResolver (for facelets) is defined in section 5.6.2.9. To solve it (for 2.3) you should raise an issue on:
https://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC But I found this one already created on Mojarra issue tracker: https://java.net/jira/browse/JAVASERVERFACES-3362 Please create an issue on the spec issue tracker. MyFaces already has some params to control the EL Resolver ordering, so I suppose this feature will help to fix the problem for 2.2.x. Besides that, we can't do anything else from this side. regards, Leonardo Uribe 2015-03-27 9:19 GMT-05:00 William Lucy <wtl...@us.ibm.com>: > > Thanks for the response, Leonardo. > > From what I can tell, the issue isn't that MyFaces can't find the > StaticFieldELResolver - that is loaded correctly.
