I working on building a simple connection with MS CRM. I am getting this 'Unconstructed message' error only when I add the Exception handler. I referred to another link Use of unconstructed message - which tells that compiler might not be sure of the message being constructed before it is handled.
But I am creating the message in a map(Transform shape) - does that not guarantees that a message is created?
Do I need to add a message assignment shape before the transform and initialize the Request message?
If you are constructing the message inside of the scope to which you have added the exception shape, then that message will be treated as Unconstructed as the exception may occur before or while the transformation occurs.
So no, the transform shape does not guarantee that the message will be constructed at all times.
Usually in this case you are better of using in your exception block the message that is on the initiating receive of your orchestration, or if you are trying to catch an exception after the transformation add a scope that starts after the transform shape and add an exception block to that.
Entity Framework's DbEntityValidationException renders a message of
Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
With a stack pointing to where the error occurred. It would be really, really useful if we could dig into the collection of errors, and write out the property and error message. Is there any way in Elmah where we can customize the output for this exception type only?
ELMAH only logs information about an error from the shared stuff on various exception. If the exception message or stacktrace doesnt contain the 'EntityValidationErrors' details, you need to save those yourself.
You can create a filter in ELMAH, implemented to check the type of the exception. If the type is DbEntityValidationException, you can dismiss that exception and raise a new one, containing a ToString of each item in the EntityValidationErrors property as the error detail.
I am attempting to connect to a .Net 1.0 web service using standard activities in WF 4.0.
I am using the SendandReceiveReplyFactory - the send portion seems to be working - however the ReceiveReplyForSend is for some reason expecting a tempuri.org namespace response rather than the www.thermo.com/informatics/xmlns/limswebservice namespace.
Could anyone instruct me on how I can cause the activity to expect the correct NS.
Thanks in advance for your help.
All the best,
DJ

The answer is to specify the namespace in the ServiceContractName Property of the 'Send' Activity using the following syntax '{http://someserver.org/test/}FileService ' in my case '{http://www.thermo.com/informatics/xmlns/limswebservice}LIMSSoap' . The syntax was sensitive to the trailing slash so a little trial and error was needed.
Many thanks to the contributors to WF4 - How to consume external web service? for the answer.
I am getting below error, when i am trying to resume Suspended(resumable) orchestration instance.
Scenario: Request went thourgh DB2 Static solicit - Response port, and it got failed because of access permission denied. I can see two instances suspended in the admin console one is related to port and another one is related to orchestration. After fixing the credentials, suspended port instance got resumed but the orchestration one is keep on failing.
Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Orchestration name'.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Any thoughts how to fix this?
Creating the above scenario using samples:
Go to BizTalk
samples/orchestrations/consumeWebservice
folder, install the
ConsumeWebService application and
publish POWebservice to IIS.
Change IIS Directory security
permissions for POWebservice, remove
anonymous or any other access.
Now drop the message you will see
suspended messages because of HTTP
status 401: Access Denied, then give
access to POWebservice either
anonymous or Windows.
Then resume
the suspended instances, one will
get disappear but
another(orchestration) one wont.
The orchestration will continue to fail with the exception because when it was suspended, the last persistence point was the receipt of the exception. This means that the orchestration will re-start (when resumed) and re-throw the exception.
Here's at article discussing some points at which orchestration state is persisted to the database: http://blogs.msdn.com/b/sanket/archive/2006/11/12/understanding-persistence-points-in-biztalk-orchestration.aspx
You can manipulate this to some extent in your orchestration design, as Richard Seroter discusses here, but generally you would do better to use failed message routing, enabling you to handle the failed messages, and terminate the failed orchestration instance.
Please correct me if I'm wrong, but is this not just normal biztalk behavior? I am not 100% sure so please let me know if this is wrong:
The outbound messaging instance was suspended because the credentials the port was using to connect to to the DB were wrong.
This caused the orchestrations making these calls to also suspend.
The suspended message instance was resumed and was processed correctly because the problem was fixed. So the call was made to the DB.
However, the orchestration instance may not be able to resume because when resumed it found itself at the most recent persistence point and the original error which was delivered back from the send port is still available to the orchestration, causing it to re-suspend.
In the error message, it actually says "If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception."
If you want to handle this sort of thing you could make the call to the database atomic. That way the orchestration will not persist itself at the point of making the DB call. If the orchestration then suspends it will resume at a point before the DB call is made, and will make the DB call as normal, which should succeed this time because you have fixed the original issue.
The only problem with this is if your DB call cannot be executed more than once with the same data without bad things happenning (is not idempotent).
I am not 100% on the above explaination. Please point out if my understanding is incorrect.
this scenario not treated by Microsoft Biztalk = Middleware FAIL.
you have to solve this at the orchestration design stage up front...

I am getting this error during serialization:
RangeError: Error #2006: The supplied
index is out of bounds.
The error occurs in AbstractMessage.as when it attempts to read input of timestamp.
After that my fault handler gets this error:
faultCode:Server.Acknowledge.Failed
faultString:'Didn't receive an
acknowledge message' faultDetail:'Was
expecting
mx.messaging.messages.AcknowledgeMessage,
but received null'
It appears to be happening as a result of an ArrayCollection coming back from the server.
Is it necessary to create custom classes to handle serialization of ArrayCollections with custom objects as shown here?
I've also followed the serialization recommendations here with no luck.
Thanks for your help!
The solution was correcting a mistake in writeExternal on the Java side. I was being very careful about the order of serialization but was writing an int as an object using writeObject. This will cause errors in completely unrelated code on the client side after it tries to readInt.
I just experienced this error myself, and it turns out it is caused by the Flash Builder Network monitor being enabled!! FB 4.0.1 this is.
I was going nuts for not finding the reason, so sharing it here for your peace of mind.
