JSF Expression Language code completion

Hello,

I'm in the process of evaluating IntelliJ IDEA to see if we could use it in the company I work for. We write JEE7 code, and I imported a Maven project. We currently develop in Netbeans and that works all fine and dandy.

But when I try to write my JSF in IDEA, for some reason it does not like Primefaces. I have a p:dataTable with a LazyDataModel attached to it, but when I try to access the variable, it tells me it's a Map instead of the Object I use in the LazyDataModel.

This means I have no (proper) code completion in expression language, which is very annoying.

I expected this would work out-of-the-box, like it does in Netbeans, but for some reason it doesn't. How can I enable the proper code completion support? (Small detail, I used project Lombok as well, but even without it, it does not work)

Kind regards
