That should be fine.

You might want to try a named page configuration to limit the impact of your
changes in testing.
public WOComponent queryDocumentAction() {
ERD2WQueryPage page = (ERD2WQueryPage)
D2W.factory().pageForConfigurationNamed("QuerySchoolAdmin", session());
...
}

What was that rule? Did it work? Why did you decide not to use the rule?

Not sure why this is happening.

Definitely not sure why this is happening. Sounds like a problem with the scope
of your rule(s)

the code below assumes the use of the Wonder templates for EOGenerate
private EOQualifier qualifierFromSender(ERD2WQueryPage sender) {
SchoolBoard sb = (((Session)session()).schoolBoard());
School aSchool = (((Session)session()).school());
EOQualifier q =
School_Admin.SCHOOLBOARD.eq(sb).and(School_Admin.SCHOOLS.eq(aSchool)).and(sender.qualifier());
return q;
}
