Simple working GWT demo?

[Fireball]

Strange, after rebooting and just running gwt:run for the clinic application and no other desktop application it's working now. I'am wondering what application could conflict? Perhaps a running eclipse with gwt plugin?

My test application isn't running, the same error occurs.

Port conflict maybe? jps is your friend. :-)

I also can't run any simple Roo/GWT application. The application obviously always fails when any of my domain entities has a field of any type other than String or Date.

When my Entities only have String or Date fields, everything is fine. When I add e.g. an Integer, Float or a reference to another entity, I get errors like this:

Sometimes this happens within an UmbrellaException.

Any advice appreciated...

[Fireball]

Yeah, the same for me. Theoretically it's working but there must be some issues related to this topic. The clinic example has the same problems.

[Fireball]

Well, look at this: http://jira.springframework.org/browse/ROO-865

:-)

[Ben Alex]

https://jira.springsource.org/browse/ROO-874 covers the integer field specific issue.

[joe_leads]

Thanks for pointing to the Jira bug.

I also created a new one for the problem I have with bidirectional references and GWT because of the missing gwt.request.SetRecord class:
