use of org.activityinfo.model.formula.CompoundExpr in project activityinfo by bedatadriven.

the class LookupKeySetTest method simpleHierarchyTest.

/**
 * In the case of a simple hierarchy, we are referencing a single form that
 * in turn has key reference fields.
 *
 * For example, if the field references a Village form, this should yield:
 *
 * <pre>
 *     Province.Name
 *        ^
 *        |
 *     District.Name
 *        ^
 *        |
 *     Village.Name
 * </pre>
 *
 * All fields are required because we ultimately need the reference to the village record.
