Uri parser can't work for short data type (Edm.Int16) for function parameter

[xuzhg]

Supposed I have a function as:

<Function Name="ShortFunction" IsBound="true">
    <Parameter Name="bindingParameter" Type="Collection(NS.Customer)" />
    <Parameter Name="number" Type="Edm.Int16" Nullable="false" />
    <ReturnType Type="Edm.String" Unicode="false" />
 </Function>

Then, I call this function as:

~/odata/Customers/Default.ShortFunction(number=1)

It fails as

"Expression of type 'Edm.Int32' cannot be converted to type 'Edm.Int16'."

The call stack is:

I am using Web API 2.2 for OData V4. Thanks.

Also consider Edm.Single and Parameter Alias
