Detailed description is here http://www.jboss.org/community/wiki/FindUsagesandRefactoringofmethodsusedinELexpressions

When editing java code I often use the find usages function to see where method is being called from. This works great until I start using the method in a .xhtml file inside an EL Expression. Another developer in my team uses IDEA 8 as his IDE and their find usages function will find all occurances of the method being used by java code AND EL expressions.

This also fits into renaming/refactoring methods. IDEA 8 allows renaming/refactoring of methods and will automatically go update any .xhtml file where an EL Expression calls that method and change it to the new name etc.

This feature would be a great addition to the jbossTools package
