Description
When calling mvn changes:announcement-generate for the attached changes.xml VTL errors are logged due to the various null fields in the Action bean:
[INFO] [changes:announcement-generate] [INFO] Creating announcement file from changes.xml... [ERROR] RHS of #set statement is null.

The attached patch goes the hard way and improves the VTL template to check for nulls. Easier would be to establish an invariant for the bean properties stating that they are never null but maybe empty, i.e. change all the setters to convert null into an empty string.
I am unable to reproduce this error. Could you provide a minimal project that exploits this bug?
