Yes, I reproduced it by simply modifying your HelloWorld example in the 
z3c.formdemo package:

Index: interfaces.py
===================================================================
--- interfaces.py       (Revision 78682)
+++ interfaces.py       (Arbeitskopie)
@@ -27,7 +27,7 @@
 class IHelloWorld(zope.interface.Interface):
     """Information about a hello world message"""

-    who = zope.schema.TextLine(
+    who = zope.schema.Int(
         title=u'Who',
         description=u'Name of the person sending the message',
         required=True)

Now the same validation problems occur for this input field.
Maybe the reason for this is my Zope3 version? I still use Zope-3.3.1. The z3c 
packages are all up to date, I use the latest SVN versions.

Best Regards,
Hermann
