Hi Erik,
Sorry not to get back to you before now.
As you've probably realized, there's no particularly clean API here to
leverage, and what you've written is isn't too far off the mark from what I
would have written.
In the Wicket viewer itself the ActionPanel uses the ActionModel (which you
discovered), and it invokes the action through the model [1], ie:
final ObjectAdapter resultAdapter =
getActionModel().executeHandlingApplicationExceptions();
In the mean time I was using the following (a bit more generic) code
ObjectAdapter resultAdapter =
actionModel.executeHandlingApplicationExceptions();
ActionResultResponse resultResponse =
ActionResultResponseType.determineAndInterpretResult(actionModel, null,
resultAdapter);
resultResponse.getHandlingStrategy().handleResults(this, resultResponse);
This way I don't have to change the Wicket component if the return type
of the action changes (and that's what I did).
It was hard to find out but it's nice to see it work finally!
The search service is calling a Elasticsearch-engine. I saw a question
about that on the mailing list. It's working now but I have to implement
the updating of the objects.
Otherwise, looks ok.
Thx
Dan

For now I've got it working. Is there a better way of executing the action
and returning the correct page?
final ObjectAdapter serviceAdapter =
getServiceAdapter(SearchService.class.getName());
final ObjectAction action =
serviceAdapter.getSpecification().getObjectAction("find");
ActionModel actionModel = ActionModel.create(serviceAdapter,
action);
List<ActionParameterMemento> parametersList =
actionModel.primeArgumentModels();
AdapterManager am = (AdapterManager)getPersistenceSession();
for (ActionParameterMemento actionParameterMemento :
parametersList)
{
ScalarModel arg =
actionModel.getArgumentModel(actionParameterMemento);
switch (actionParameterMemento.getNumber())
{
case 0:
arg.setObject(am.adapterFor(this.query));
break;
case 1:
if(this.preference != null)
{
arg.setObject(am.adapterFor(SearchService.Type.valueOf(this.preference)));
}
break;
case 2:
arg.setObject(am.adapterFor(boost));
break;
default:
break;
}
}
ObjectAdapter resultAdapter = action.execute(serviceAdapter,
actionModel.getArgumentsAsArray(), InteractionInitiatedBy.USER);
ActionResultResponse resultResponse =
ActionResultResponseType.COLLECTION.interpretResult(actionModel, null,
resultAdapter);
resultResponse.getHandlingStrategy().handleResults(this,
resultResponse);

Hi,
I'm trying to create a generic search component that should show up in
the footer bar. Creating the component itself is not a problem but
returning the results is. The component is calling a service like this:
final SearchService searchService = lookupService(SearchService.class);
SortedSet<SearchResult> results = searchService.find(this.query, null, 1);
I was thinking about returning a StandaloneCollectionPage or ViewModel by
using ActionResultResponseType but I can't figure out to create the model
right. So how to set the response page with the right parameters?
Thanks,
Erik
