Re: Caused by: java.lang.IllegalArgumentException: Cannot fetch unpersisted entity
Can you post the class firing the below request? requests.find(proxyId).with(resource, action, subjects).fire(callback); -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Caused by: java.lang.IllegalArgumentException: Cannot fetch unpersisted entity
Hi ,
The AbstractRequestFactory in the client throws this exception, method
public P extends EntityProxy RequestP find(EntityProxyIdP
proxyId) {
if (((SimpleEntityProxyIdP) proxyId).isEphemeral()) {
throw new IllegalArgumentException(Cannot fetch unpersisted
entity);
}
but the weird issue is that the data is persisted to the database.
RuleProxy is a new entity with no persistent id, but
ActionProxy,ResourceProxy and Subject all have a persistent id.
The entities/proxy are as follows
public interface RuleProxy extends EntityProxy {
...
abstract ResourceProxy getResource();
abstract void setResource(ResourceProxy resource);
abstract ActionProxy getAction();
abstract void setAction(ActionProxy action);
abstract Setcom.citi.gpf.cues.client.proxy.SubjectProxy
getSubjects();
the call to persist:
request.persist(RuleProxy).fire() ; I am doing something wrong
here ???
then I call a finder method as follows
requests.find(proxyId).with(resource, action,
subjects).fire(callback);
I am just wondering whether I am calling the finder method before the
persist request has been returned.
thanks,

What does throw this exception? (I suppose Hibernate, Datanucleus or
whichever JPA implementation you're using)
And when? (which method, and what's the stack-trace?)
Does request factory support inheritance ?
Yes.
