Issue 1353:  Marshaling engine issue (obv-rtf)
Source:  (, )
Nature:  Revision
Severity: 
Summary: Summary: Using the idl defined in Issue # 1352, we have the send() method, in interface Foo, which takes a Base value type as it"s formal parameter.  Now supposet we wish to pass a Derived value type. When marshaling the list of repository id"s, the marshaling engine has no notion of the formal type of the parameter , thus it 
 does not know how many safe repository id"s it needs to marshal.

Issue #2: 

Using the idl defined in Issue #1353, we have the send() method, in
interface Foo, which takes a Base value type as it's formal
parameter.  Now supposet we wish to pass a Derived value type. When
marshaling the list of repository id's, the marshaling engine has no
notion of the formal type of the parameter , thus it 
does not know how many safe repository id's it needs to marshal. 

Proposal: 

The OutputStream method write_Value(java.io.Serializable obj) should
be changed to 

    public abstract void write_Value(java.io.Serializable obj, String
formal_type_id); 

where formal_type_id is the repository id of the formal type of the
argument.  Thus, the marshaling engine now has a way of comparing
repository id's (obtained from the static table in Issue #1) and is
able to determine how many repository id's to marshal on to the wire.
