Hi,

I had the following problem when trying to render a page based on this java:

...
else if (getCustomer() == null){
setTrafficMonitorThresholds(getTrafficMonitorThres holdService().fetchByReseller(getWebUtils().getCur rentReseller()));}
...

This page also is used dependent on another render of a collection which works however this one doesnt :S

The place that it is erroring after debugging and stepping through is:


public void setIdentifier(Identifier identifier) {
this.identifier = identifier;
}

<many-to-one
name="identifier"
class="Identifier"
cascade="none"
access="property"
column="identifierid"
/>

The result set is comming from this hibernate query:

<query name="searchByResellerForThreshold">
<![CDATA[
from TrafficMonitorThreshold
where reseller = ?
]]>
</query>

And called this hibernateDAO

@SuppressWarnings("unchecked")
public List<TrafficMonitorThreshold> fetchByReseller(Reseller reseller)
{
return getHibernateTemplate().findByNamedQuery("searchByR esellerForThreshold",reseller);
}

and this DAO Service

public List<TrafficMonitorThreshold> fetchByReseller(Reseller reseller){
return this.trafficMonitorThresholdDao.fetchByReseller(re seller);
}

Many Thanks In advance
