Looks like you missed the "Set the default Entity Configuration" step where you modify applicationContext-entity.xml. Also, since this occurs in core, you will have to either do a full rebuild of the project or build core and then build site in order to get these changes.

i did also this step, i added in the file core/src/main/resources/applicationContext-entity.xml :
<bean id="org.broadleafcommerce.profile.core.domain.Customer"
class="com.mycompany.profile.core.domain.HCCustomerImpl"
scope="prototype"/>
I made a full rebuild, and i still have the problem, it's strange .

Perhaps you are logging with a previously-created customer? If so, you would have an entry in the BLC_CUSTOMER table but not a corresponding entry in the HC_CUSTOMER table. Try registering a new Customer. What happens in that scenario in relation to the database?

I think is a cash problem, because in the logs and just before my exception stack trace i have :

http-8443-1 WARN strategy.AbstractReadWriteEhcacheAccessStrategy - Cache blStandardElements Key org.broadleafcommerce.profile.core.domain.CustomerImpl.customerAttributes#102 Lockable : null
A soft-locked cache entry was expired by the underlying Ehcache. If this happens regularly you should consider increasing the cache timeouts and/or capacity limits
http-8443-1 ERROR workflow.DefaultErrorHandler - An error occurred during the workflow

in the log we can see that the application use org.broadleafcommerce.profile.core.domain.CustomerImpl.
do you see anything that can help me plz.
thanks .

Possible, but if you have restarted the application then the Hibernate cache is cleared. What happens with the scenario that I presented above?

in each test i use a new customer, and i still have the same problem.
