Flexmojos 7.0.1 NullPointerException while generating sources

Hi folks,

I'm migrating my projects to flexmojos7.0.1 (flex-sdk4.13) from 6.0.1.
I have a project that generate the sources by using graniteds23 generator.

When I made changes in order flexmojos7.0.1 to be used I've got
NullPointerException.
