    cdi-example issue

    Franck Garcia Newbie

      Hi there,


      I try to run cdi example but I run into this issue.

      Brand new to errai (and GWT) so any pointers will be appreciated.

          Hi Franck,


          got the same issue here. It was due to an old timstamped errai-common.jar from my local .m2 folder.

          Apparently maven-2 builds replace SNAPSHOT with an timestamp and maven-3 stopped doing this.


          So to fix this:

          1. delete ~/.m2/repository/org/jboss/errai on your developer machine
          2. mvn clean install on a fresh https://github.com/errai/errai checkout
          3. The decompiled errai-common.jar CollectionToList class should be the same as https://github.com/errai/errai/raw/ecd7e0bc82e167528f09388b49e67a6f90608165/errai-common/src/main/java/org/jboss/errai/common/client/types/handlers/collections/CollectionToList.java it was much longer in the stale artefact..
          4. build and deploy the cdi-example again


          Best Regards

            Ralf, thanks for the explanation.As an alternative, I was able to make it work in checking out tag v1.1-beta2 that points to errai v1.1-Final.

              Yes, working with 1.1-Final is a good idea at the moment. However, I'll take a look at the serialization issue:

                This problem is fixed in master. However to prevent these sort of issues, make sure to run a clean build that updates all the snapshot dependencies:


                mvn -U clean install
