Send an email with your .java file, the problem is in there.

Subject: [Tapestry-developer] Could not find an adaptor for class X
I'm working very hard to wrap my brain around Tapestry concepts and syntax,
but need some help with this one.
I keep getting an exception with the text "Could not find an adaptor for
class Person".
On a PersonList page, I've got a Foreach component that has as its source a
List of Person objects. I then need to access attributes of each object.
It's really straightforward and not unlike some of the tutorials.
Here's the clip from the PersonList.page file:
<component id="e" type="Foreach">
<binding name="source" expression="personList"/>
<binding name="value" expression="jondough"/>
</component>
<component id="insertPersonID" type="Insert">
<binding name="value" expression="jondough.personID"/>
</component>
<component id="insertAddress" type="Insert">
<binding name="value" expression="jondough.address"/>
</component>
What is an adaptor? The Person class is in the same directory as the
PersonList class. I've been working on this one all day. Thanks in advance
for your help!
