Hi,
I didn't know about deprecation of <f:loadBundle>. At least, this is not
mentioned in VDL:
https://docs.oracle.com/javaee/7/javaserver-faces-2-2/vdldocs-facelets/f/loadBundle.html
Where is this issued/discussed?
At least, the intent indeed was that <f:importConstants> should have same
mechanism as <f:loadBundle>. However, instead of request scope, the values
can be placed in application (global) scope. At least not in page/template
scope as that would not work (it would break your ajax example) and also
not in view scope (technically possible but plain inefficient).
A faces-config.xml based configuration is a reasonable idea. Perhaps even
better.
Cheers, B
