Hi,
Just FYI: I opened JAVASERVERFACES_SPEC_PUBLIC-946 (see [1]) to
discuss your misinterpretation of #{resource['...']} with the JSF EG
in order to find a more convenient way to address this issue than the
custom method in the managed bean, because I think it is a "mistake"
many users make.
Regards,
Jakob
