1. Re: Generic types and marshalling
1 of 1 people found this helpfulHi Anton,
Thanks for taking the time to package up an example app that illustrates the problem. This is a huge help!
Now for the bad (good?) news: I downloaded and unzipped the attached application, and the whole thing built properly for me. No errors generating either the client or server marshallers:

I also tried running the app in Dev Mode (mvn gwt:run), and that worked too.

2. Re: Generic types and marshalling
Thanks Jonathan
Thats strange that it worked for you.
I did, however, find the problem. I simply needed to ensure the event classes had default no-args constructors.
Thanks again.

3. Re: Generic types and marshalling
For mutable @Portable value types like all the ones in your example app's shared package, you don't need to write explicit default constructors. Errai Marshalling knows about the implicit public no-args constructor, and will use it.
Immutable types, of course, don't generally have a no-args constructor. In this case, you need to choose one constructor and annotate each of its parameters with @MapsTo. But this doesn't apply to any of the @Portable types in your example app; they are all mutable and have either an explicit or implicit no-args constructor.
Which leaves us with a mystery as to what caused your build to fail. Perhaps some old .class files that needed to be wiped out by a Maven clean?
