Hi
I tried to set the null value with MyFaces 2.2.4 and it works as expected.
But trying with Mojarra 2.2.7 I get this:
javax.faces.component.UpdateModelException: java.lang.NullPointerException

Take a look your classpath, probably something is not right.

Getting NPE when Flow Scope parameter evaluates to null.
If no value is entered for firstName before “continue” on
campaigns/campaigns.xhtml is clicked, the NPE below thrown. Otherwise the
page2.xhtml is displayed as expected.
