Problem using Roo generated class

Hi all:

Are there special steps required before using a Roo generated form class?
I currently get the following exception when I try to use a generated form:

java.lang.ClassNotFoundException: javax.validation.MessageInterpolator$Context

This error does not occur when I bring up the generated application. The application starts up and works fine. However when I add a reference to the generated class in my vaadin component the exception above occurs. Any ideas?


Problem fixed: I replaced the javax.validation sources jar file referenced in the pom.xml with the actual javax.validation class jar file reference.
