That means there's a exception when we create the model,which is a special case 
we haven't find.

Would you mind to take a full screenshot for me ?

Also , try to create a new run configuration to check if problem still there.

I just build a new nightly version that only return a error message instead of 
Exception, and you should now able to see the real error message in the view.

I am sorry about the inconvenience, if you don't mind , please try our latest 
nightly again.

FWIW, I was seeing this same error with 1.3.3 from the release update site and 
since switching to the latest 1.3.3.201203170835 from the updatesite-nightly it 
works as expected now.

I have the same problem while clicking "My proj"->run as ->run configuration. 
it opened a blank content with left menu "Jetty" - "My Proj" shown and the 
following popup

Items model shouldn't be null
An error has occurred. See error log for more details.

my installed version of "Run Jetty Run Feature (Required)" is 
1.3.3.201203161919.
I would like updating it to latest 1.3.3.201203170835 as the above tonylove... 
suggested, but there is no update available. 

Please advise. thx a lot.

For solving this issue for workaround ,
you could try to remove the run configuration and create a new one.

It might happen when RJR got exception from resolving the classpath items,
I will look into this for more details.

You could also find the version 1.3.3.201203161919 in the nightly update-site.

I also have this problem. I'm using version:

  Run Jetty Run Feature (Require)   1.3.3.201203161919  runjettyrun_feature.feature.group   http://code.google.com/p/run-jetty-run/

In my case it only happens if a project for which a RJR target is added is 
closed when opening the "Debug configurations". If I open the project before 
opening the "Debug configurations" I no longer get the "Update LCD..." errors.

Can you update the main updatesite to at least version "1.3.3.201203170835" 
suggested by testmcu* above, so people don't get this error when installing the 
default?

Either open all the projects you specified inside your run-jetty-run 
configurations or update to the nightly build mentioned before
