BizTalk 2004 :: messages mutating when they shouldnt be
|
|
|
|
Hello all,
I have a BAZZAR one:
I have a message coming into an orchestration (M1) which is copied to a new
message name (M2) and then is passed to a C# component where it is being
modified and returned back to the orchestration.
For some reason I cant understand the messages are all being mutated once
the component is callled. M1 should never be modified but it equals the
value of M2 once the component is called. This is very frustrating since
I need the unmodified M1 later in the orchestration. Even if I set M1 =
M3 for example, M3 is ALSO mutated to the value of M2 !!!!!
I have tried 100 different message combination and nothing changes this behavior.
The component is called in a message assignment shape like this:
......
M2 = M1
M2 = Stater.Isvcs.Iface.MO.OFKA.Reporting.Support.addEnrich.ReturnOkResponse(M2);
//Check the value of M1
xDoc = M1;
System.Diagnostics.Debug.WriteLine("M1 = " + xDoc.OuterXml);
.....
Even if I set M1 to an xml doc variable and then set M2 to that variable
its being mutated.
Help !!

It is all related to how objectoriented languages work. As long as you
are only changing the pointers, you are not actually creating a new
object. Try this:
xmldocVariable1 = M1;
xmldocVariable2 = new System.Xml.XmlDocument();
xmldocVariable2.loadXml(xmldocVariable1.OuterXml);
M2 = M1;
M1 = xmldocVariable2;
M2 =
Stater.Isvcs.Iface.MO.OFKA.Reporting.Support.addEnrich.ReturnOkResponse(M2);

| Thanks for the reply, Jan.
Makes a bit more sense although I wonder why there is so much information
about the immutability of messages.

True - a bit weird since they can actually be changed a number of
places...
