>             Project: Olingo
>          Issue Type: Bug
>          Components: odata2-core
>    Affects Versions: V2 2.0.7, V2 2.0.8
>            Reporter: Daniel Horvath

> Hello colleagues,
>  
> We have found a strange behaviour in the update process of an entity in Olingo (2.0.7)
OData 2.0.
>  
> When we try to set a property to {color:red}null{color} value it is not set but the old
value remains. It is caused by the implementation of:
> {color:red}setProperty(final Method method, final Object entity, final Object entityPropertyValue,final
EdmSimpleType type, String propertyName){color}
> method in {color:red}org.apache.olingo.odata2.jpa.processor.core.access.data.JPAEntity{color}
class.
>  
> In line 472 there is a check if the entityPropertyValue is null then skip the setting
of the value completely.
> The protocol documentation says that we can use the Nullable facet on all the EDMSimpleType-s
because it’s a Commonly Applicable Facet. (Section 2.2.1.1.1. in https://winprotocoldoc.blob.core.windows.net/productionwindowsarchives/MC-CSDL/%5bMC-CSDL%5d.pdf)
> We think that the setting of null value to a Nullable property should be allowed.
> If you have further questions please feel free to contact me.
> Best regards,
> Daniel
