Both 'success' and 'failure' payload objects are null. This should never occur.

[noosy]

I was just wondering, I have a void return type for my RPC method and
it's resulting in this exception appearing in my log when I call it
using the gwtrpccommlayer library:

Failure in Asynch dispatch thread. java.lang.RuntimeException: Both
'success' and 'failure' payload objects are null. This should never
occur.
java.lang.RuntimeException: Both 'success' and 'failure' payload
objects are null. This should never occur.
at
com.seguedevelopment.gwtrpccommlayer.client.GwtRpcClientSideProxy
$AsynchCallBackRunnable.run(GwtRpcClientSideProxy.java:613)

Is there a reason why it is not appropriate to have a void return
type?

Thanks.

Thanks for reporting it. I'll give it a look.

fixed in latest maven snapshot build

ahh, that's a bad dependency.  I had to compile my own version of Guice.  I'll get about fixing that ASAP.  It should download the dependency automatically.

And the goal you have to execute gwt hosted mode is "mvn war:exploded gwt:run."  I suspect that you don't have to execute war:exploded but I haven't figured out the correct configuration quite yet.

Hi Dan -

Excellent stuff, I've installed the Mercurial and Maven plugins for my Eclipse instance.
I have been able to take the latest code from

https://gwtrpccommlayer.googlecode.com/hg/

I then tried to execute some of the Maven tasks: "Meven test" and I get the following error (see below)
I looks like I need the Guice jar. A couple of questions:

• Does/Should maven dowload this package directly for me (it seemed to do that for other dependencies)
• Assuming I need to do this manually, can you provide me a link (so I know I have the correct version)
• Which Maven task do I execute to start-up the GWT hosted mode environment?
