Re: [orion-dev] Handling long running validation

[Simon Kaegi <Simon_Kaegi@xxxxxxxxxx>]

Hi Chris,

All service calls are under the covers asynch and return a then-able promise unless you are directly using the service object. So, yes just return a deferred and the rest is handled for you.
Also... if you're returning a deferred in a service implementation but are otherwise not using Dojo I would suggest using "orion/Deferred" as it has no dependencies and should load faster than dojo especially when used in a plugin.


For an example see -- bundles/org.eclipse.orion.client.core/web/plugins/filePlugin/fileImpl.js

Hi all,
 
Apologies if I am missing something obvious here. I have a validator and outliner that make relatively long running xhr requests to a server. I would like this to happen asynchronously but I can't work out how to do this as when the service I registered is called, it seems to be expected to return synchronously. Is there a way to either trigger the rest of the validation myself when the request returns or to return a dojo deferred object  which Orion can call then() on?
 
Thanks,
Chris.
