Dan Haywood updated ISIS-691:
-----------------------------
Description:
Several issues:
1. for entities, if the reference is null, the drop-down
(EntityLinkSelect2Panel) always shows the first object in edit mode
2. for value types (eg enums), it is not possible to set a null value (!)
~~~
To replicate (1) add the following property to the simple archetype's
SimpleObject class:
// //////////////////////////////////////
// other (property)
// //////////////////////////////////////
private SimpleObject other;
@Column(allowsNull="true")
@MemberOrder(sequence = "1")
// @Mandatory
public SimpleObject getOther() {
return other;
}
public void setOther(final SimpleObject other) {
this.other = other;
}
public List<SimpleObject> choicesOther() {
List<SimpleObject> list = container.allInstances(SimpleObject.class);
return list;
}
~~~
To replicate (2),
ToDoItem
@javax.jdo.annotations.Column(allowsNull="true")
public Subcategory getSubcategory() {
and
ToDoItemContributions
public ToDoItem updateCategory(
final ToDoItem item,
final @Named("Category") Category category,
final @Optional @Named("Subcategory") Subcategory subcategory) {
...
}
and
public static enum Category {
Professional {
@Override
public List<Subcategory> subcategories() {
return Arrays.asList(null, Subcategory.OpenSource,
Subcategory.Consulting, Subcategory.Education);
}
}, Domestic {
@Override
public List<Subcategory> subcategories() {
return Arrays.asList(null, Subcategory.Shopping,
Subcategory.Housework, Subcategory.Garden, Subcategory.Chores);
}
}, Other {
@Override
public List<Subcategory> subcategories() {
return Arrays.asList(null, Subcategory.Other);
}
};
public abstract List<Subcategory> subcategories();
}
