Support for auto-complete and conditional choices #14

Closed richardpawson closed 10 years ago

richardpawson commented 11 years ago

In Naked Objects for .NET we now support auto-complete for reference properties (when editing an object) or parameters (in an action dialog).

At present, here is no obvious way to expose this via RO other than using implementation-specific extensions. My suggestion (for RO v 1.1. or greater) is that this could be supported simply by adding one or more links to the property or parameter JSON, with a new recognised rel-type. The link would take a single string argurment and would return a List representation of links to the objects. One unresolved part of this solution would be whether the URL link looked like an action, or had a new form, representing a 'method' rather than an an action.

If sufficiently generalised, the same pattern could also cover another NOF capability we would like to surface, which is 'conditional choices' - where the list of choices can vary dependent upon values entered for other properties/parameters (e.g. selection of a Country specified/filters the list of Counties).

Note: Need to make sure we cover the scenario where auto-complete and/or conditional choices needs to return a set of value types (e.g. a set of strings) rather than reference object list. I assume that in this case the list of strings would just need to be turned into a single scalar type e.g. a single string with the values comma separated. (This would be consistent with the way that a (fixed) set of choices is handled in the spec right now.
