AIF: ‘EndElement’ is an invalid XmlNodeType

Klaas Deforche — Tue, 20 Apr 2010 09:31:08 +0000

Hi all.

I got this error when developing a C# .NET application that consumed a AIF web service, and couldn’t find a solution online so let me share mine :-).

The problem was that I initialised my queryCriteria wrong:

CriteriaElement ace = new CriteriaElement();
ace.FieldName = "AccountNum";
ace.Value1 = "000001";

I forgot the specify the datasourcename and operation:

CriteriaElement ace = new CriteriaElement();
ace.FieldName = "AccountNum";
ace.Value1 = "000001";
ace.DataSourceName = "VendTable";
ace.Operator = Operator.Equal;

AIF: HTTP Error 404.3 – Not Found

After installing an AIF web server and deploying services on it, I got an error when I tried to browse my web service http://myhost:82/MicrosoftDynamicsAXAif50/itemservice.svc.
The error was:

HTTP Error 404.3 – Not Found

When I tried to add a web reference the svc in visual studio .NET, I got a similar error:

HTTP Error 404 – Not Found

I solved it by using the method described on the AIF blog:
http://blogs.msdn.com/aif/archive/2008/12/12/http-error-404-3-is-received-when-calling-a-web-service.aspx

Basically, execute the following command on your web server:

ServiceModelReg.exe -i -x

After that, everything worked fine.

AIF: The class method for the specified action %1 could not be found

When you get this error:

The class method for the specified action %1 could not be found

It probably means you have regenerated you classes using the AIF document wizard, or that you have imported the AIF classes without id’s.

You can use this job to fix the class id’s in the AIFAction table:

static void KlForFixAIFActions(Args _args)
{
AIFAction aIFAction;
ClassId classId;

// inner method:
// spit string at delimeter, keep left substring
str lSplit( str _s, str _delimeter )
{
str s = "";
int pos;
int len = strlen( _s );

pos = strfind( _s, _delimeter, 0, len );
s = strdel( _s,pos,len-pos+1);

return s;
}
;

// fix all actions
while select aIFAction
{
// get 'real' classid
classId = classname2id(lSplit(aIFAction.ActionId, '.'));

// check if classid and classname match
if(aIFAction.ClassId != classId)
{
if(classId == 0)
{
// class does not exist
warning(strfmt("Class %1 does not exist", lSplit(aIFAction.ActionId, '.')));
}
else
{
// doesn't match
// update classid
ttsbegin;
aIFAction.selectForUpdate(true);
aIFAction.ClassId = classId;
aIFAction.update();

info(strfmt('Action %1 updated', aIFAction.ActionId));
ttscommit;
}
}
}

info('done');
}

Start learning about AIF

Hi everyone.

When I was starting to learn about AIF, I made a list of the resources I used to get familiar with it.
I know how hard it is to learn AIF (there’s a lot you need to know), so I’d like to share this list of links with you.

General:

Blogs:

Videos:

Axaptapedia:

AIFEnvelopeTool

Books:

Inside Microsoft Dynamics AX 2009: Chapter 17 The Application Integration Framework

Of course, there are also some articles on this blog that are tagged AIF.

Hope you find these links useful!

Run AIF inbound and outbound manually

Klaas Deforche — Wed, 17 Feb 2010 17:51:53 +0000

To have AIF import and export message, you have to have 4 batch tasks running (all about it here on TechNet). However, when developing, it is inefficient (and also tad tedious) to wait for those batches.

Here are two jobs to run inbound and outbound messages manually, so you don’t have to wait for the batches to pick them up.

Inbound:

static void KlForrunAIFInbound(Args _args)
{
;
// read the messages
new AifGateWayReceiveService().run();

// process the messages in queue
new AifInboundProcessingService().run();

info("done");
}

Outbound:

static void KlForrunAIFOutbound(Args _args)
{
;
// process messages in queue
new AifOutboundProcessingService().run();

// send messages
new AifGateWaySendService().run();

info("done");
}

Ofcourse, you can put this code in classes, or combine them so they are executed together. Because inbound messages can trigger outbound messages, it’s better to process the inbound messages before the outbound messages.

AIF: The path %1 does not exist or is not accessible from an AOS server. Always use a UNC path.

Klaas Deforche — Tue, 08 Dec 2009 17:03:27 +0000

Hi guys,

It seems like I’m going to be doing a lot of AIF in the future, so I’d like to share the first AIF error I came across:

The path C:\AIF does not exist or is not accessible from an AOS server. Always use a UNC path.

You can get this error when setting up channels.
While I immediately know what the problem was (you have to use shares), my less technical-minded colleague didn’t know what to do.

This is what Wikipedia has to say about ‘UNC path’:

The Microsoft Windows UNC, short for Universal Naming Convention or Uniform Naming Convention, specifies a common syntax to describe the location of a network resource, such as a shared file, directory, or printer. The UNC syntax for Windows systems has the generic form:

\\ComputerName\SharedFolder\Resource

So there you have it, you have to use a shared folder in stead of a local folder.
This is logical, as AIF runs on server, and the AOS can not access your local folders.
