Cancel Request?

[hasc...@qyotta.de]

Hi,

first let me thank you for this project and your efforts. We are successfully using restyGWT in three project with no problem up to now! thanks!

One thing that we couldn't solve on our own is that we sometimes need to cancel a request. With the plain GWT RequestBuilder is is possible:

RequestBuilder requestBuilder = new RequestBuilder(
    RequestBuilder.GET, FOOBAR_SERVICE_URL);

Request request = requestBuilder.sendRequest("",
   new RequestCallback<ResultList>() { .... });

...

//user clicked cancel button
request.cancel();

Is this possible somehow with restyGWT too?

/cheers

if you use the Resource object itself you will get a Method which does the sending and there you have access to the request object used.

if you use RestService then that is not possible. BUT it looks straight forward to change the generated code (RestServiceClassCreator) to return the Method object used for sending the payload as return value of the RestService method (if the return value is declared as Method and not as void).

would that help ?

Hi Christian,

yes, that would be enough! Let me see if I can contribute the change myself. However, if your are faster then feel free to commit it.

Hi Christian,

it seems that it is enough to let the service method return a Request-Object. On the Request-Object, I can call „cancel“. Did I miss something?

cheers

that is OK. the only thing is that we need to stay backward compatible,
i.e. if the method in RestService interface declares void that the
generated implementation should not return anything. if the method
returns Request then the generated code should just return that.

Hi Christian,

sorry for not being exact, it seems like the mentionen Java-Class ALREADY does that. I cloned the git-repo and saw that it is possible to use JsonpRequest and Request.

cheers
