[jira] [Created] (OLINGO-630) Exception is thrown when serializing
the complex type properties of entities in Car/manufacturer example Service
( serializing Manufacturer entities having Address complex type property)
Kevin Ratnasekera created OLINGO-630:
----------------------------------------
Summary: Exception is thrown when serializing the complex type properties of entities in Car/manufacturer example Service ( serializing Manufacturer entities having Address complex type property)
Key: OLINGO-630
URL: https://issues.apache.org/jira/browse/OLINGO-630
Project: Olingo
Issue Type: Bug
Components: odata4-server
Affects Versions: (Java) V4 4.0.0-beta-03
Reporter: Kevin Ratnasekera
Priority: Trivial
java.lang.ClassCastException: java.util.ArrayList cannot be cast to org.apache.olingo.commons.api.data.ComplexValue exception is thrown in the ODataSerializer method
writeComplexValue((EdmComplexType) edmProperty.getType(), property.asComplex().getValue(),selectedPaths, json);
Root cause for the issue is when invoking
property.asComplex()
public ComplexValue asComplex() {
if(isCollection()) {
return null;
}
return isComplex() ? (ComplexValue) value : null;
}
here the value Object is first initialized to List<Property> at the Car/manufacturer Service later it is being casted to ComplexValue.
Herewith attached a patch, proper type is set to value Object, so that no cast exaception is thrown later when serializing complex types.
