I'm running into an issue where a converter i've setup is failing (or
appears) to fail to execute. First, might I make the assumption that type
converters and validators can be represented as beans. Reason being is
because I need to be able to do dependency injection via spring.
So, my problem is this: I've got an object 'CostCode' that has several
primitive properties and one 'Organization' object property. When the user
submits the form below, the validation specifications fail because the
system expects an Organization object as costCode.organization and instead
the validation processes receive a String representation of a LongID (the
long ID of the chosen Organization).
So, I thought, this is a perfect opportunity to use a converter... It's not
working, though. See the code below:
### RELEVANT TEMPLATE CODE ###
<s:form ... >
<s:textfield name="costCode.code" maxlength="20"></s:textfield>
...
<s:select name="costCode.organization" list="organizations" listKey="id"
listValue="name" label="Organization..." />
</s:form>
### xwork-conversion.properties ###

import java.util.Map;
import org.apache.log4j.Logger;
import org.apache.struts2.util.StrutsTypeConverter;
import com.ktm.tt.dao.hibernate.organization.impl.OrganizationDaoImpl;
public class OrganizationConverter extends StrutsTypeConverter {
private OrganizationDaoImpl organizationDao;
private static final Logger LOG =
Logger.getLogger(OrganizationConverter.class);
public Object convertFromString(Map context, String[] values, Class toClass)
{
Long organizationID = new Long(values[4]);
LOG.debug("running OrganizationConverter.convertFromString!!!");
return organizationDao.findById(organizationID);
}
public String convertToString(Map context, Object o) {
LOG.debug("running OrganizationConverter.convertToString!!!");
return null;
}
public OrganizationDaoImpl getOrganizationDao() {
return organizationDao;
}
public void setOrganizationDao(OrganizationDaoImpl organizationDao) {
this.organizationDao = organizationDao;
}
}

on 'class com.ktm.tt.struts.action.organization.CreateCostCode: Error
setting expression 'costCode.organization ' with value
'[Ljava.lang.String;@30fd981a'
So, what ends up happening is that the framework tries to determine the
conversion from a String to an Organization object... and fails.
I have the log levels jacked and I have _never_ seen the log statements I
have in place.
Any ideas???
