Is there a way to pass to the client upon a failed server data operation an error message associated with the operation or/and a record as a whole rather than with a specific field? I am so far not able to find one, so I attach messages to a dummy field name and then retrieve them in from the DsResponse in an EditFailedHandler. It works but seems kind of kludgy.
Call dsResponse.setFailure() and call setData() with the (singular) error message as a String.
Note that this type of error goes to central error handling (see RPCManager.addErrorHandler()), where the default is to show whatever message the server sent in a warning dialog.
Thank you very much! This works great for me.
BTW, there seems to be no RPCManager.addErrorHandler(). You possibly had on mind RPCManager.setHandleErrorCallback() but I did not really try this because default behavior suits me.
Yes, you’re correct, it’s really setHandleErrorCallback().
