Re: Using the restful interface with view models

[Erik de Hair]

Hi Dan,

Thanks for your help. I'm not sure about the architecture.
Would the following architecture do the trick:
- write my own xml web service, accepting xml complying to the view 
model's xsd
- use the jaxb service to unmarshall the input to a domain entity
- use the wrapperfactory to wrap the actual service method call for 
validation to be handled by Apache isis
- how to use a possible validation error as a response?

Thanks,
Erik

Hi Erik,
sorry not to reply sooner.

I'm afraid that serializing objects in this fashion isn't possible in the
RO viewer.  The best/only workaround I can give you right now is to define
the property as a string and then to send the JSON as a string and
deserialize within the receiving action:


public void exampleAction(String addressAsJson, String foo) {
     Address address = fromJson(addressAsJson);
}

Or, you could use XML of course.  The JAXB-style of view models would make
the deserialization easier actually, so you might want to go that route,
using JaxbService [1]

Anyone? I can do this writing my own service class but I would like to
use Apache Isis' error handling etc.

Still figuring some things out...

Is it possible to expose some service method using the RO viewer with
complex type parameters like below?

public void exampleAction(Address address, String foo){
     // process input...
}

public class Address {
     private String zipCode;
     private String number;
}

I tried annotating the Address class with @ViewModel but then the RO
viewer expects a link to an existing view model. I would like our
external partners using the RO viewer to create json-objects (or xml?)
that will be accepted by 'exampleAction'. How to do that?

Thanks,
Erik

Hi,

For some use case we have a Wicket wizard using Apache Isis view
models where each step enriches the view model as returned by the
previous step until it is ready to submit. I was trying to redo this
using the restful interface but I can't figure out what's the
objectId of the returned view model. I need that I to start the
actions related to the next step.

So I have an action

/objects/WbaAvailability/{objectId}/actions/startAccessOrderCopper/invoke
where object WbaAvailability is a view model. An other action
(executed before) returns a list of WbaAvailabilities. But how to use
one of these and invoke the startAccessOrderCopper-action?

Thanks,
Erik
