How to handle errors?

Hi, I'm new to CKFinder.

I'd like to know how to handle errors when they occure.

Currently, when an exception occures, the full stack trace is displayed in a popup, on the client side! Is it possible to prevent those popups and to provide a custom handler method instead?

Thanks in advance.

Re: How to handle errors?

Hello.

This is more like a general JavaScript issue and not a CKE issue per se. I do my uncatched error handling like this answer on StackOverflow: http://stackoverflow.com/a/5328206/694325 - it is also userful to extend that so that it logs to server via AJAX if you want to. Of course, I would love to catch all errors in dev/testing and have custom error handling for each predictable error, but this method works for those uncatched errors.

Thanks for the help req.

I actually solved my problem by implementing a special WebExceptionHandler for CKFinder (I use Java and Spring MVC). I now return an appropriate http code and a simple message (that can be displayed to the end user) when an exception occured in the CKFinder servlet.

Re: How to handle errors?

For the records, I also had to modify the ConnectorServlet class, so handleError() throws the exception it received as a parameter, when the command is not an instance of XMLCommand, instead of calling ErrorCommand#execute(). With the default code, response.sendError() was called and that prevented any reset of the response object after that. Since I needed to modify the response to fit my need, in my custom WebExceptionHandler, I had to remove this part of the code.
