You are getting the NPE because you are not using a factory method to create
your D2W pages. The factory creates a d2wContext. You should never use the
WOComponent constructor directly either. Always use WOApp, WOAction, or
WOComponent's pageWithName() factory method.
If you want to reuse a query, ERD2W does that :-) Look at the saved queries
stuff in ERD2W. I believe David Holt has an example of this somewhere.
You'll want to be careful with that though. Your model changes over time. The
queries you store in the database don't. You'll need to validate them before
you run them. I don't know if ERD2W does this for you. I think it does, but
I've not gotten around to using saved queries just yet. (I need to separate
the implementation from the userPreferences stuff for it to be useful to me.
You may have the same requirement.)
