[jira] [Created] (ISIS-1874) Parented checkboxes fails - NPEs and
incorrect facets.
Dan Haywood created ISIS-1874:
---------------------------------
Summary: Parented checkboxes fails - NPEs and incorrect facets.
Key: ISIS-1874
URL: https://issues.apache.org/jira/browse/ISIS-1874
Project: Isis
Issue Type: Bug
Reporter: Dan Haywood
Two separate issues:
# NPE for a parented collection with no toggle box column (the AssociatedWithProvider is always created, but may return a null toggle box column; this isn't guarded for.
# When a choices facet is installed for a parameter, doesn't check the type of the parameter against the collection, meaning cannot invoke action.
Workaround: disable the "associateWith" or memberOrder
Example of (1) - fails with NPE (though action is executed)
{code:java}
@Getter @Setter
private SortedSet<Occupancy> occupancies = new TreeSet<>();
// associated via .layout.xml
public Occupancy newOccupancy(
final @Parameter(optionality = Optionality.OPTIONAL) LocalDate startDate,
final Unit unit) {
Occupancy occupancy = occupancyRepository.newOccupancy(this, unit, startDate);
occupancies.add(occupancy);
return occupancy;
}
public LocalDate default0NewOccupancy() {
return getTenancyStartDate();
}
public List<Unit> choices1NewOccupancy() {
return getProperty()!=null ? unitRepository.findByProperty(getProperty()) : unitRepository.allUnits();
}
{code}
Example of (2) - fails with AgreementRole incompatible with Party. Workaround is to ensure there's an explicit autoComplete or choices
{code:java}
@javax.jdo.annotations.Persistent(mappedBy = "agreement", defaultFetchGroup = "true")
@Collection(editing = Editing.DISABLED)
@CollectionLayout(render = RenderType.EAGERLY)
@Getter @Setter
private SortedSet<AgreementRole> roles = new TreeSet<>();
@MemberOrder(name = "roles", sequence = "1")
public Agreement newRole(
final AgreementRoleType type,
final Party party,
final @Parameter(optionality = Optionality.OPTIONAL) LocalDate startDate,
final @Parameter(optionality = Optionality.OPTIONAL) LocalDate endDate) {
createRole(type, party, startDate, endDate);
return this;
}
public List<AgreementRoleType> choices0NewRole() {
return agreementRoleTypeRepository.findApplicableTo(getType());
}
public LocalDate default2NewRole() {
return getEffectiveInterval().startDate();
}
public LocalDate default3NewRole() {
return getEffectiveInterval().endDate();
}
{code}
^^^ the problem triggers on Party, not on AgreementRoleType, because the latter has an explicit choices method.
