Primefaces 6.1

Hello,

I am working on a project which previously used eclipse and I finally convinced my team to try intellij. We have a big spring project which uses java 8 and primefaces 6.1. I have an issue in my xhtml files when I want to define a parameter as follows:

<ui:param name="bean" value="#{myActualBean}" />

The issue is that whenever I try to use the declared parameter I get the following warning, and the actual staff that is bothering me is the fact that we do not have autocomplete for our defined variable(bean) even if we have for it's actual value(myActualBean).

Can you please help me with this issue, I can not seem to find any solution for it...
