Summary: EntityType with NavigationProperty Key
Key: OLINGO-204
URL: https://issues.apache.org/jira/browse/OLINGO-204
Project: Olingo
Issue Type: Question
Components: odata2-core
Affects Versions: V2 1.1.0
Reporter: M Carissimi
Hello,
I have some EntityTypes which define as Key one of the NavigationProperties.
For example EntityType AA_SEL_TEST_2 specifies as part of the Key the property
OBJECT_REF which is a NavigationProperty for AA_SEL_TEST_1
{code}
<EntityType Name="AA_SEL_TEST_2">
<Key>
<PropertyRef Name="NAME"/>
<PropertyRef Name="OBJECT_REF"/>
</Key>
<Property Name="GUID" Type="Edm.String" Nullable="false"/>
<Property Name="NAME" Type="Edm.String" Nullable="false"/>
<Property Name="FLOW" Type="esys_producer.NumberAndUnits" Nullable="false"/>
<NavigationProperty Name="OBJECT_REF"
Relationship="esys_producer.AA_SEL_TEST_2_to_AA_SEL_TEST_1"
FromRole="r_AA_SEL_TEST_2" ToRole="r_AA_SEL_TEST_1"/>
</EntityType>
<EntityType Name="AA_SEL_TEST_1">
<Key>
<PropertyRef Name="NAME"/>
<PropertyRef Name="IS_ACTIVE"/>
<PropertyRef Name="PRODUCTION_DATE"/>
</Key>
<Property Name="GUID" Type="Edm.String" Nullable="false"/>
<Property Name="NAME" Type="Edm.String" Nullable="false"/>
<Property Name="IS_ACTIVE" Type="Edm.Boolean" Nullable="false"/>
<Property Name="PRODUCTION_DATE" Type="Edm.DateTime" Nullable="false"/>
</EntityType>
{code}
When I request the feed containing all entries for EntityType AA_SEL_TEST_1 I
get all the data, but when I request the feed for entries of type AA_SEL_TEST_2
I get an exception
{code}
SEVERE: java.lang.NullPointerException

...
{code}
My entity processor class (ResourceEntitySetProcessor) builds a
Map<String,Object> containing all the required data and invokes the
EntityProvider.writeFeed() method passing the map.
How can I resolve the issue?
Regards
