Issue 4804:  section 1.18.2 of the OMG IDL mapping document ptc/00-01-08 (java-rtf)
Source:  (, )
Nature: Clarification
Severity: Significant
Summary: There is something that is unclear in your CORBA spec that I think is causing incompatibility problems between various IDL compilers. 

Given the following IDL: 

------------------------------------------------- struct Protection { string str; }; 

typedef Protection ProtectedEntity; 

typedef sequence<ProtectedEntity> ProtectedEntityList; 

typedef ProtectedEntityList ProtectingEntity; ------------------------------------------------- 

Should a holder class for ProtectingEntity get generated? I ask this because some IDL compilers generate it and others do not (very frustrating!). 

In section 1.18.2 of the OMG IDL mapping document ptc/00-01-08 spec I found this: "Holder classes are generated for sequence and array typedefs only. The "unwound" type's Holder class is used for the other cases.". 

Since this is a typedef of a typedef, but the original item was a sequence, should the ProtectingEntityHolder.java file get generated or not?

Description

There is something that is unclear in your CORBA spec that I think is
causing incompatibility problems between various IDL compilers. 

Given the following IDL: 

------------------------------------------------- struct Protection {
                                                  string str; }; 

typedef Protection ProtectedEntity; 

typedef sequence<ProtectedEntity> ProtectedEntityList; 

typedef ProtectedEntityList ProtectingEntity;
------------------------------------------------- 

Should a holder class for ProtectingEntity get generated? I ask this
because some IDL compilers generate it and others do not (very
frustrating!). 

In section 1.18.2 of the OMG IDL mapping document ptc/00-01-08 spec I
found this: "Holder classes are generated for sequence and array
typedefs only. The "unwound" type's Holder class is used for the other
cases.". 

Since this is a typedef of a typedef, but the original item was a
sequence, should the ProtectingEntityHolder.java file get generated or
not?
