WCF REST Starter Kit not filling base class members on POST
- by HJG
I have a WCF REST Starter Kit service. The type handled by the service is a subclass of a base class. For POST requests, the base class members are not correctly populated.
The class hierarchy looks like this:
[DataContract]
public class BaseTreeItem
{
[DataMember]
public String Id { get; set; }
[DataMember]
public String Description { get; set; }
}
[DataContract]
public class Discipline : BaseTreeItem
{
...
}
The service definition looks like:
[WebHelp(Comment = "Retrieve a Discipline")]
[WebGet(UriTemplate = "discipline?id={id}")]
[OperationContract]
public Discipline getDiscipline(String id)
{
...
}
[WebHelp(Comment = "Create/Update/Delete a Discipline")]
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "discipline")]
public WCF_Result DisciplineMaintenance(Discipline discipline)
{
...
}
Problem: While the GET works fine (returns the base class Id and Description), the POST does not populate Id and Description even though the XML contains the fields.
Sample XML:
<?xml version="1.0" encoding="utf-8"?>
<Discipline xmlns="http://schemas.datacontract.org/2004/07/xxx.yyy.zzz">
<DeleteFlag>7</DeleteFlag>
<Description>2</Description>
<Id>5</Id>
<DisciplineName>1</DisciplineName>
<DisciplineOwnerId>4</DisciplineOwnerId>
<DisciplineOwnerLoginName>3</DisciplineOwnerLoginName>
</Discipline>
Thanks for any assistance.
