When I define an entity (e.g. Project) with an email field and create a new project without explicitly initializing the email field. I get a null pointer exception even when I check for null pointers in the application. The npe is caused by the following code:

if( !(org.webdsl.tools.Utils.equal(this.getEmail().length(), null) ||
org.webdsl.tools.Utils.equal(255, null)) &&
this.getEmail().length() > 255
)

which is triggered by this call:

if(!ThreadLocalPage.get().isRollback())
{
ThreadLocalPage.get().validateEntitiesAfterAction();
}

The stack trace:
