DynaTable, "Exception while dispatching incoming RPC call "

[Anders Branderud]

Hello!

Today I started to use GWT. I tried to run the example DynaTable, but
it doesn't work. I imported the files of that directory into a new
project.

When I run DynaTable I get this error: http://itlosningar.appspot.com/'

When I run it in Eclipse I get the same error and this is printed out:

The same error occurs both on both of my PC's.
Does anyone have a solution to this problem.

Thanks in advance!
