[omniORB] Sequence in Any marshalling failure

[Franzen, Holger]

Actually i got my code runnig by changing the idl definition:

[From]
...
	enum XMLDataNodeType { ... };

	struct XMLDataAttr { ... };
	typedef sequence<XMLDataAttr> XMLDataAttrSeq;

	// forward declaration
	struct XMLData;
	typedef sequence<XMLData> XMLDataSeq;

	struct XMLData {
		XMLDataNodeType type;
		string name;
		string value;
		XMLDataAttrSeq 	attributes;
		XMLDataSeq children;
	};
...

[To]
...
	enum XMLDataNodeType { ... };

	struct XMLDataAttr { ... };
	typedef sequence<XMLDataAttr> XMLDataAttrSeq;

	struct XMLData {
		XMLDataNodeType type;
		string name;
		string value;
		XMLDataAttrSeq 	attributes;
		sequence<XMLData> children;
	};
	typedef sequence<XMLData> XMLDataSeq;

So avoiding the forward-declaration for the recursive field 'children'
makes the code work. why i don't know maybe an internal typecode
mismatch?

thank's,
 holger.
