Forum | Appery.io

Hi,
I'm used to use:
servicename.updateComponents(responseCachedJSON);
for update components on appery.io with a cached Json. Since the new appery.io interface arrives it seems that this code doesn't work any more (perhaps due to the new mapping interface for services).
How can I reach the same behaviour with javascript and the new appery.io interface (update components with a cached json)?
Is there an api reference for new javascript functions?

Thanks

Marco

Hello Marco,

You can make the mapping from storage variable or you can use the echo service parameter

Hi Evgene,

thanks for the reply. I haven't clear how to make mapping through storage variable. I already have the full json response as string as a storage variable. I need to automatically map that json with the appery.io components without recalling the service (exactly the thing that updateComponents method do).
I haven't tried to use echo yet but the documentation you linked says:
em"Be sure to turn off the Echo service when using the app in production."/em
I haven't understand if this note is valid also if I use echo with javascript... can you clarify please?
Any other suggestions for solve the problem? It will be great if I can use again the updateComponents method or a similar way because with one line of code it makes exactly what I want. If you confirm that use echo with javascript in production is safe I'll go for that.

Thanks again

Marco

Marco,

Please try the following
pretest_list_service.requestOptions.echo = '[{"id":"11111111","createdAt":"2013-05-23 13:59:24.980","updatedAt":"2014-10-03 19:50:20.114", "s":"6","n":1},{"id":"22222222222","createdAt":"2013-05-27 15:36:27.002","updatedAt":"2014-10-03 19:50:18.311","s":"5","n":1}]';
restservice1.execute();
test_list_service.requestOptions.echo = ";/pre
Where test_list_service is the service name
restservice1 is the name of the instance of the service test_list_service on the page
