I have updated my webapplication from JSF 1.1 to 1.2 and accordingly also the faces-config.xml.
When I open the updated faces-config.xml in Eclipse, it showed me that "variable-resolver" is deprecated.
My example: I used to have "<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>"
which I changed (when the above was highlighted to be deprecated) to "<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>"
It would be nice if such deprecations could be shown in NetBeans as well!
(This might well apply to other configurations, so this issue should be re-assigned if needed.)
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.
Thanks for your cooperation,
NetBeans IDE 8.2 Release Boss
