Exception handling using the html-bridge

Hi,

we are starting to create plugin views using the html-Bridge.  All was working well, until we started working on exception handling.

In the dataservice, an error has happened while retrieving the data -so a RuntimeException is thrown.   But in our htmlview - in the

.fail(function(jyXHR, Status, error) - the value of  error is always "Not Found".

I thought I was doing something wrong, so I tried the same in the globalview-html plugin - but the results are the same.

Here I just threw a fake RuntimeException during the save Settings.

>throw new RuntimeException("abcd");

This gets caught in the Service Controller - in the handleDataAccessException() - which returns

>return Collections.singletonMap("message", ex.getMessage());

Here we can see the message

"Error while saving Setting in null\globalview/Settings.properties"

But in the settingsView.js, the .fail  is called, and the error is also "Not Found".

Could you please tell me what is wrong here?

thanks

Cathy
