If you attempt to use a message variable within an orchestration and have
not created an instance of it, you get an error.

I know two ways to do this are:
1. If the message is like the incoming message, you can use an expression
shape and just say Msg2 = Msg1;
2. You could create a dummy transform shape that has any source schema and
the required destination schema and without creating any links within the
map, let the map create the instance. Kind of a hacked way of doing it.

But what would another method of creating an instance be? Would you create
an instance of an XMLDocument and then somehow associate it with a schema?
What would the code in the expression shape look like?

Thanks.

Hello !

A way to do what you want is to assign your message variable in an
expression shape using a helper, like that :
msgMyMessage = aHelper.NewMessage();

And, in your helper (in C#), you could have :
public static XmlDocument NewMessage()
{
XmlDocument doc = new XmlDocument();
doc.LoadXml("<ns0:Root
xmlns:ns0=\"http://my.namespace.here\"><someTagsHere></someTagsHere></ns0:Ro
ot>");
return doc;
}

That _could_ be a way. Not the best, firstly because the XML is hard coded,
but it is an example.....

hi,

why isn't this working directly in the expression shape?

also, i'd like to load a schema instead of hardcoding the xml... what would
be the syntax?
i cannot i think use .net because i must conform to BPEL and target systems
could be others than .net...

thanks!
