Hi,
This is about to drive me mad. I have a custom PopertyEditor that I
register in initBinder(). When setAsText() gets called, I get a
NullPointerException that I can't seem to figure out. Here's the
stacktrace:
DEBUG [btpool0-1] CountryPropertyEditor.setAsText(31) | Entering
CountryPropertyEditor.setAsText( 1 )
DEBUG [btpool0-1] CountryPropertyEditor.setAsText(34) |

This is the PropertyEditor:
package com.firstworldtoys.model;
import java.beans.PropertyEditorSupport;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import com.firstworldtoys.service.GenericManager;
public class CountryPropertyEditor extends PropertyEditorSupport
{
protected final transient Log log = LogFactory.getLog(getClass());
private GenericManager<Country, Long> countryManager = null;
public CountryPropertyEditor()
{
}
public CountryPropertyEditor(GenericManager<Country, Long>
countryManager)
{
setCountryManager(countryManager);
}
public void setCountryManager(GenericManager<Country, Long>
countryManager)
{
this.countryManager = countryManager;
}
public void setAsText(String s)
{
log.debug("Entering " + getClass().getSimpleName() +
".setAsText( " + s +
" )");
try
{
log.debug(countryManager);
Country country = countryManager.get(new Long(s));
super.setValue(country);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
I know that countryManager is not null, and I am able to use the same
instance to retrieve a list of Country objects in referenceData().
This is in my applicationContext-service.xml:
<bean id="countryManager"
class="com.firstworldtoys.service.impl.GenericManagerImpl">
<constructor-arg>
<bean class="com.firstworldtoys.dao.hibernate.GenericDaoHibernate"
autowire="byType">
<constructor-arg value="com.firstworldtoys.model.Country" />
</bean>
</constructor-arg>
</bean>
Any suggestions? I'm really stuck.
Thanks!
Greg
