Validation Error on Simple a4j:support Call
I am trying to add an a4j call to an existing Faces form. I am getting two errors and not sure if the are related.
The errors:

I have the following in my faces-config.xml file:
<managed-bean>
<managed-bean-name>pc_TiersAndLevels</managed-bean-name>
<managed-bean-class>TiersAndLevels</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>pc_DocumentEdit</managed-bean-name>
<managed-bean-class>DocumentEdit</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>docid</property-name>
<value>#{param.docid}</value>
</managed-property>
<managed-property>
<property-name>tiersAndLevels</property-name>
<property-class>TiersAndLevels</property-class>
<value>#{pc_TiersAndLevels}</value>
</managed-property>
</managed-bean>
And the important parts of the backing bean:
