Hello all,
Suppose I want to create several NodeTypes, each of them containing a Property called
"category" whose value is constrained to a List of values.
The constraint list will need to be expanded as more categories will be added. This
change should be reflected then in all NodeTypes which contain the "category"
property.
Unfortunately, it seems that the PropertyDefinition is somehow static,
getValueConstraints() only allows to define one time the constraints. There is
no functionality to create a link to a dynamic Property, so that all changes
made in the Property will be reflected in all NodeTypes using this Property.
The only solution I see at the moment is to create a custom implementation,
outside the repository, to mimic the NodeType interface,
including inheritance. But doing so will create a lot of disadvantages;
including the fact that there will be no checks done by the repository itself
for compliance to the NodeType of new Nodes.
Are you aware of any posibility to create such a functionality using the
repository?
you could e.g. create a node type myapp:Category that extends from
mix:referenceable. now for each category (e.g. book, dvd, etc) you can
create a node of type myapp:Category.
in your custom node types make your "category" property a REFERENCE
property and restrict it to myapp:Category.
you can add new categories (nodes of type myapp:Category) at any time.

Thanks a lot,
