It's a great help to get warnings about unknown properties. But, if something isn't a property, and might been recognized not being one, you'll get a misleading hint:

Bean:
    public Map<String, String> getPages() {

JSF Page:
            <h:link value="#{msg.lblSummary}"  outcome="#{sessionTools.page}"/>
"unknown property page"
This is a usefull warning, cause ther is no such property

            <h:link value="#{msg.lblSummary}"  outcome="#{sessionTools.pages.MainApp}"/>
"unknown property MainApp"
This is an annoying hint. In this case pages.MainApp is a valid expression to retrieve a value of the map.
Switching off these hints is no option, cause I want to get hints about false expressions.
NB should invstigate and recognize "pages" as Map (same for List, ...) and treat "MainApp" as key. Thus, no warning will be displayed.
