Exception Handling of scripted data source for preview [message #915429]

Dear all,
I'm using scripted data sources (JAVA) successfully for quite a while now.

Now I would like to present error messages in the preview of the designer (only in the designer, in my application I do not have this problem).
For example, passwords are transmitted as parameter to my datasource. If the password is wrong, at the moment the user gets the whole stack trace in the preview of the designer.
I'm searching for:

- a possibility to configure the designer in a way it will only show the exception message but not the whole stack trace

or

- a possibility to return an error message

It is OK to present the message in the preview window, an alert box is not necessary (but would be nice).

Is there a way to solve this?

Thank you in advance!

Best regards

Mark

Is your code surrounded with Try Catch blocks? I know when using a JavaScript scripted data source you can wrap up code in try catch blocks and then swallow the error and use a column to return an error.
