Excellent! Feel free to stop by seam-dev IRC and chat with the group. We are starting to grow again and if we can't help you, we'll at least make you laugh a few times :)

Visited seam-dev and Aslak pointed me to some git reading, so I need to enlighten myself on the diff/patch and do a pull request to the upstream repo.

Excellent! Ah, but did you laugh? :) If not, be sure to come back when lincoln's evil twin is around :)

I'd like to commit a new sub-module: seam-wicket-mock; to get SeamWicketTester in place. Then write up some NumberGuess tests.

Great. As you've probably noticed, the Wicket module seem to have left its tests somewhere :) So any test is a good test at this point.

Secondly, I have written a blog app (very simple example) which for the most part demonstrates CRUD operations using Scala, CDI, Wicket and off course have Arquillian/ShrinkWrap. This might be a nice show off as opposed to LiftWeb.

Awesome! This would be a great addition to the examples for the Wicket module. I look forward to the pull request.

The fork I'm working on is checked out by: git clone git://github.com/seam/wicket. It this a right starting point? Should it be forked in a different way, upon making pull request to the upstream repo?

It's funny you should ask because a guide is currently in the works! In the meantime, checkout the Hacking AS7 guide for a sample workflow.

Weld and Seam 3 is fun! Scala coding makes it even more fun. Though, Java and Faces is my core focus in my main project.

We'd love to get your help and/or input on Seam Faces as well!

Kariem, what modifications have you done?

Our modification were meant to let us use a current version of Hibernate Search and support dependency injection via @Inject. Not a big thing and from what I have seen this should already be done in the current beta.

On the topic of contributing to the project, I really liked the announcement on Hibernate's move to github: Hibernate moves to Git + Git tips and tricks.

Not this time; as I didn't see lincoln's evil twin in there :)

Calling Lincoln's evil twin. Come out to play!

What makes me laugh is having a descending dev cycle, so you'd except alpha3 to come after beta1 ;-)

We like to think outside of the box :)

I got my env set up, which means I might be productive.

...and there was much rejoicing!

Ove,

I've committed your changes after some reworking. Trust that all of your changes got applied, they just may look a bit different. You may have to reset hard to HEAD in order to get in sync.

I noticed that your XML files had tabs in them. The convention in the Seam project is to expand tabs to spaces. If you could please switch that it will make merges simpler ;)

Here are the dev guidelines for Seam: Seam development guidelines

Thanks again!

Hi Dan,

I have been trying to get Seam 3, Wicket and RESTeasy to work for a few hours now. Finally decided to use the numberguess example as a reference, so I

m eager to get it to work.

Chances are you are getting this because you have an EL API on the classpath when Jetty is starting. It's likely being pulled in by a Maven dependency. Execute mvn dependency:tree and figure out what needs to be excluded.

It would be helpful for others following this discussion if you could post your dependencies. Just the output of dependency:tree would do. Thanks!

Dan,

I pulled the numberguess straight from github. I'm now on another machine, I'll try to reproduce the problem.
