> FunctionImport returns null
> ----------------------------
>
> Key: OLINGO-137
> URL: https://issues.apache.org/jira/browse/OLINGO-137
> Project: Olingo
> Issue Type: Bug
> Components: odata2-jpa
> Affects Versions: V2 1.0.0
> Reporter: David Radenkov
> Assignee: Anirban Roy
> Fix For: V2 1.2.0
>
>
> I have JPA-Entity "User" and I try to return it with FunctionImport:
> @FunctionImport(name = "myFunc",entitySet = "User", returnType =
> ReturnType.ENTITY_TYPE , multiplicity = Multiplicity.ONE, httpMethod =
> @HttpMethod(name = Name.GET))
> public User currentUser(){
> User currentUser = getLoggedInUser();
> return currentUser;
> }
> But the response from that function is:
> <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";>
> <code/>
> <message xml:lang="en">
> An exception of type 'NullPointerException' occurred.
> </message>
> </error>
> I have tried to chage the ReturnType and Multiplicity but the response was
> same.
> For example If I re-factor the function to return Integer and set the Return
> Type to SCALAR it works fine.
