You probably haven't implemented the IFormComponent.getName() method.

Hmm, not quite following. NameSet is extending BaseComponent and
implements IFormComponent.
I fixed it again by slightly modifying NameSet.jwc (added a line before
the component spec).

NameSet in a class hierarchy? Not sure how your particular situation
is happening but looking at
org.apache.tapestry.enhance.DefaultComponentClassEnhancer.validateEnhan
cedClass()
I see that it walks up the class hierarchy looking for abstract method
declarations that have not been implemented by Tapestry in the
generated subclass.
So, I would look up in the hierarchy and ensure there are no
unimplement abstract methods that tapestry would miss at enhancement
time (no <property-specification> etc).

So, I am developing a Tapestry application and we have started adding
in components. This the third time I have run into this error and
cannot figure out the root cause. The second I ran into it I changed
the .jwc file (removed some extraneous xml) and it went ahead just
fine
no problem. I have since made some other changes and am getting the
same exact error again (these changes are unrelated to the component).
Here is the error (with part of the stack trace):

The odd thing is this:
While we have an abstract class for NameSet, there is no method for
getName, and there is no property called name in the .jwc file.
I am running it on tomcat 4.1.30 (although had the same exact problem
on 5.0.something.
Any ideas on this, it's very irritating. If need be, I'll attach the
.jwc and .html files.
