Hi!
I had some problems migrating the entitystore fra 1.3 to 1.4. I discovered
that populating entities with namedassociations failed:
org.json.JSONException:
JSONObject"namedassociations"<https://wiki.cantara.no/pages/createpage.action?spaceKey=retrade&title=%22namedassociations%22&linkCreation=true&fromPageId=24184572>
not
found.
at org.json.JSONObject.get(JSONObject.java:617)
at org.json.JSONObject.getJSONObject(JSONObject.java:733)

org.qi4j.spi.entitystore.ConcurrentModificationCheckConcern$ConcurrentCheckingEntityStoreUnitOfWork.getEntityState(ConcurrentModificationCheckConcern.java:129)
The code in MapEntityStoreMixin.createNamedAssociations gave me a clue:
private Map<QualifiedName, Map<String,EntityReference>>
createNamedAssociations( JSONObject jsonObject,
EntityDescriptor entityDescriptor
)
throws JSONException
{
Map<QualifiedName, Map<String,EntityReference>>
namedAssociations = new HashMap<QualifiedName,
Map<String,EntityReference>>();
JSONObject namedAssocs = jsonObject.getJSONObject(
"namedassociations" );
for( AssociationDescriptor namedAssociationType :
entityDescriptor.state().namedAssociations() )
{
Map<String, EntityReference> references = new
HashMap<String,EntityReference>();
try
{
JSONObject jsonValues = namedAssocs.getJSONObject(
namedAssociationType.qualifiedName().name() );
for( String name : jsonValues )
{
Object jsonValue = jsonValues.getString( name );
EntityReference value = jsonValue ==
JSONObject.NULL ? null : EntityReference.parseEntityReference(
(String) jsonValue );
references.put( name, value );
}
namedAssociations.put(
namedAssociationType.qualifiedName(), references );
}
catch( JSONException e )
{
// NamedAssociation not found, default to empty one
namedAssociations.put(
namedAssociationType.qualifiedName(), references );
}
}
return namedAssociations;
}
I moved JSONObject namedAssocs = jsonObject.getJSONObject(
"namedassociations" );
into the try-block, and that seems to eliminate the problem.
I guess this is a bug.
Best Regards,
Dag
