Custom Business Logic / CodeRunner update problem

fabio-souza · February 27, 2016, 7:03pm

Hi! Since the last update on February 22nd my Custom Business Logic stopped working so I recompiled it with the latest release (downloaded from console) and now I can´t publish or debug it with CodeRunner, here is the error I´m getting.

Thank you

There is a known problem with CodeRunner on Windows. We’re working on it, should be fixed soon.

fabio-souza · February 29, 2016, 8:00pm

I could get it deployed and debugged on linux but my code´s still being ignored/ bypassed.
This is happening since the last update.

Thank you for any help.

mark-piller · February 29, 2016, 8:06pm

Please let us know your APP ID.

Thanks,
Mark

Thanks

mark-piller · February 29, 2016, 8:22pm

Thanks. Could you show what event handlers you deploy and what API you invoke (which should trigger the event handlers)?

fabio-souza · February 29, 2016, 8:34pm

Hi, I´m calling the afterCreate Event handler for “Plays” Data Table, here is the code
for PlaysTableEventHandler.java

I tried throwing some exception but coderunner still didn´t catch it.

fabio-souza · February 29, 2016, 8:40pm

Sorry, the API is javascript

mark-piller · February 29, 2016, 9:38pm

I didn’t understand what “sendNewSongMsg” method has to do with the event handler.

Also, I’d like to see the client-side code which you believe should trigger the event handler.

harsh-agrawal · February 29, 2016, 9:53pm

I am having similar while trying to override “Before Create” event handler for custom model. Whatever logs or exception I put in code, the Coderunner doesn’t show any logs or exception in debug mode. From the docs it looks like an easy things to do, but somehow it is not working. Coderunner is successfully deploying the handlers in both Debug and Production mode but the handlers are not showing any SystemLogs such as System.out.println .

fabio-souza · February 29, 2016, 9:53pm

The sendNewSongMsg method sends a message so devices connected on the specified channel will get notified,
here is the javascript function, it´s working fine, but the event handler should do some validation and change the “Plays” object status.

harsh-agrawal · February 29, 2016, 10:03pm

@Fabio check this http://support.backendless.com/t/backendless-business-logic-not-call

fabio-souza · February 29, 2016, 10:26pm

Thank you Harsh it seems to be the same problem, as Mark said the fix will be published on the next update.
Still coudn´t find the create method on JS API.

fabio-souza · March 3, 2016, 9:22pm

The handler worked for a while today but stopped.

fabio-souza · March 14, 2016, 9:40pm

I´ve downloaded and updated my code to 3.0.10 and my Event Handlers are still
being ignored by backendless. Do I have to update the javascript API too?

mark-piller · March 15, 2016, 5:45am

Fabio,

What event handlers do you implement?

Regards,
Mark

fabio-souza · March 15, 2016, 10:05am

Hi Mark!
I implemented AfterCreate and AfterUpdate on PlaysTableEventHandler.

Thanks

mark-piller · March 15, 2016, 10:11am

Do the event handlers show up in the Debug tab of the Business Logic screen?

fabio-souza · March 15, 2016, 10:14am

Yes, on Debug and Production

mark-piller · March 15, 2016, 10:17am

What does your code for the Update operation look like?

Could you please post here complete output from CodeRunner?

Could you also try it from REST console and see if the event handler is triggered? You can read more about REST Console here (it talks about GET, but you can use it for PUT and POST requests):
