Michael Bolz commented on OLINGO-1042:
--------------------------------------

Hi [~Michele EnergySys],

This is not a bug, it is a design decision based on the OData specification 
with its {{URI}} types (see section 
[2.2.3.5|https://msdn.microsoft.com/en-us/library/dd541212.aspx]) which is 
reflected in Olingo in the {{org.apache.olingo.odata2.core.uri.UriType}} class 
and {{org.apache.olingo.odata2.core.Dispatcher->dispatch()}} method.

According to this a function import which results in a collection (EntitySet) 
is dispatch to the {{readEntitySet(...)}}.

Best Regards, Michael

> Hello
> I have implemented some functions on my OData v2 service and they appear on 
> the $metadata as follow
> {code}
> <FunctionImport Name="UserAllowedApplications" 
> ReturnType="Collection(myproducer.Application)" EntitySet="Application" 
> m:HttpMethod="GET"/>
> {code}
> When I invoke a function using a GET request, the 
> EntitySetProcessor.readEntitySet() method ins invoked instead of 
> FunctionImportProcessor.executeFunctionImport().
> This seems to be the incorrect behaviour... is there anything that I can do 
> to ensure the correct method is invoked?
> Thanks
