--------------------------------------
Summary: XML syntax unbound action with a collection of entities
as parameter
Key: OLINGO-1580
URL: https://issues.apache.org/jira/browse/OLINGO-1580
Project: Olingo
Issue Type: Question
Components: odata4-server
Affects Versions: (Java) V4 4.9.0
Reporter: Florent Albert
I have an unbound action which takes a collection of entities as a parameter.
This action works fine when the request body is JSON. However, when the request
body is XML, it fails with HTTP 400 "failed to read feed".
This is what my request body looks like:

I tried removing the <atom:feed> tag and have my entries directly under
MyCollectionParameter, it didn't work either.
Looking at the XML Deserializer, it looks like there is a bug as it expects the
parameter name to be "<atom_ns>feed" (cf.
{_}org.apache.olingo.server.core.deserializer.xml.ODataXmlDeserializer.entitySet(XMLEventReader,
StartElement, EdmEntityType){_})
Before opening a bug, I wanted to make sure I'm not making a syntax mistake.
