h1. Less code
If you use jface databinding to code your swt views in Eclipse you'll get spared from writing listeners and updating code by hand. JFace databinding offers very nice abstractions and automatisms that offer funcitonalities for the vast majority of the tasks where you have to listen for user input and update the view accordingly.
*Premise*
If you implement a complex and highly dynamic UI in Eclipse you'll have to code many many many listener that wait for user actions. Those listeners mostly do nothing spectacular but update widgets and models in reaction to the user inputs. You end up with a lot of repetitive boilerplate code. UI frameworks in the non-java land (ex. http://qt.nokia.com/products/ Trolltechs QT) already have approaches that are far more elegant and slick than what we knew for Swing and SWT.
By luck Eclipse has progressed in this area (since 2005!) and offers neat abstractions that help a lot in this area and lead to far more concise and a less verbose implementations: Jface Databinding!

*=== Environment ==============================*
- *jBPM Version*: 4.4

*=== Problem description =========================*
I've been going through the example processes provided in the developer guide ( http://docs.jboss.com/jbpm/v4/devguide/html_single/#group http://docs.jboss.com/jbpm/v4/devguide/html_single/#group) and encountered a problem in the GPD. When using a group activity in a process the graphical designer doesn't show the group activity in the process flow (see attached print-screen). This is a problem since my intention is to use the image produced by the graphical designer in documentation.
I have been through the jBPM wiki, user forums, etc. but nothing seems to address this issue in any way. Is there a reason for this to occur? Is there any work-around?
Kind Regards,
Adel Haider

Hello,
since yesterday I got exceptions when I try to open XML or XHTML files in JBoos tools editor.
I tried Eclipse 3.4.2 with JBossAS Tools Version: 2.0.2.v200910211631N-H194-GA
as well as Eclipse 3.6.1. with
JBossAS Tools
JBossAS Tools Version: 2.2.0.v20100908-1606-H23-M2
Version: 2.2.0.v20100908-1606-H23-M2
and JBoss Tools RichFaces for Eclipse Version: 3.2.0.v20100908-1606-H23-M2
but all I got is

[JBoss Tools] - JBoss/Red Hat at Eclipse Summit 2010

--------------------------------------------------------------
I'm looking forward to attend for my first time Eclipse Summit 2010 where as I until now only been at EclipseCon's.
http://www.eclipsesummit.org/ http://www.eclipsecon.org/summiteurope2010/static/image/friends/100x100_g...
I (luckily?) won't be speaking at the conference, but Chris Aniszczyk and Nick Boldt will:
Tuesday at 14:00, Nick is having a 4-hour symposium together with Henrik Lindberg (Cloudsmith) on the topic of http://www.eclipsecon.org/summiteurope2010/sessions/?page=sessions&id=1924 "What's in a Build? Best Practices and Requirements". The intent of this is to work out best practices for how to mange the process of developer, nightly, milestone and release builds for Eclipse projects. Something that we have spent alot of time on in the JBoss Tools project but still know can be improved - looking forward to see if what others have done in projects of our scale/size.
Wednesday at 10:30, Chris is doing his http://www.eclipsecon.org/summiteurope2010/sessions/?page=sessions&id=1658 "Using Git in Eclipse" together with Matthias Sohn (SAP) showing of the wonders of Git and the EGit tooling for it.
Thursday at 10:30, Nick Boldt is participating together with Henrik Lindberg (Cloudsmith), Jason Van Zyl (Sonatype), Oisin Hurley and Thomas Hallgren (Cloudsmith) in http://www.eclipsecon.org/summiteurope2010/sessions/?page=sessions&id=1869 "Build Systems Exposed: Strengths & Weaknesses of Build Technologies at Eclipse" . This talk will compare the various build systems in use at Eclipse - will we finally reach some concensus ? :)

I'm looking forward to meet old and new Eclipse friends - if you want to find me, look for someone with a JBoss Tools jacket!
See you there!

[JBoss Tools] - Seam runtime does not exist error but... it exists

I had to rebuild my workspace, JBDS environment and I did it with the latest version of JBDS 3.0.1 GA. I had a lot of "Problems" and resolved all but one that I can't figure out.
I have a seam project with 3 parts, assettag, assettag-ear, assettag-ejb. I am getting this error on the assettag project:
Seam Runtime "seam" specified for Seam project "assettag" does not exist.
It is a bold-faced LIE! :-)
The "seam" runtime does exist for Seam project "assettag". I've recreated that runtime, added another runtime, restarted, deleted, re-added, etc. and this error will not go away no matter what I do. I believe it is related to some other Property on this project or one of the related projects. Just to prove it I'm attaching a screen shot of the Seam Settings.
What else might influence this project so that it would produce this error?
TDR
