I think I'm getting close to figuring this one out, but I'm now stumped. Maybe someone else can build on what I've got or point out what I'm doing wrong...

Using the information in the following link, I tracked down how to easily get to the number sequence reference being used for product numbers, as well as how to get the next number from a number sequence reference:

msdn.microsoft.com/.../aa608474.aspx

Here's what my X++ code looks like:

[SysEntryPointAttribute(true)]
public Num getNextProductNumber()
{
    NumberSeq numberSequence;

    numberSequence = NumberSeq::newGetNum(EcoResProductParameters::numRefProductNumber());

    return numberSequence.num();
}

I then used the information in the link below to expose my code via WCF:

I'm able to connect to the service from C# and call the method, but I'm getting an AIFFault with an error message of "Number selection is canceled". I'm a newbie on X++ development and not yet familiar with the debugging tools, so I used a crude approach for now of evaluating some variables and stuffing them into a string that I can then view from my C# code. I basically wanted to make sure that I was getting a reference to the correct number sequence, and I also evaluated a few other properties that I thought might possibly affect my ability to get a new number. Here's the kludgy code I used for that:

[SysEntryPointAttribute(true)]
public str getNextProductNumber()
{
    str status = "Initializing;";
    NumberSequenceReference numberSequenceReference = null;
    NumberSequenceRange nextNumberUnformatted;
    Num nextNumber;
    str numberSequenceCode;
    str nextNumberUnformattedString;
    str isContinuousString;
    str isManualString;
    str isBlockedString;

    try
    {
        status = status + " Getting number sequence reference;";
        numberSequenceReference = EcoResProductParameters::numRefProductNumber();

        numberSequenceCode = numberSequenceReference.numberSequenceTable().NumberSequence;
        status = status + " Number sequence code: " + numberSequenceCode + ";";

        isContinuousString = enum2str(numberSequenceReference.numberSequenceTable().Continuous);
        status = status + " Continuous: " + isContinuousString + ";";

        isManualString = enum2str(numberSequenceReference.numberSequenceTable().Manual);
        status = status + " Manual: " + isManualString + ";";

        isBlockedString = enum2str(numberSequenceReference.numberSequenceTable().Blocked);
        status = status + " Blocked: " + isBlockedString + ";";

        nextNumberUnformatted = numberSequenceReference.numberSequenceTable().NextRec;
        nextNumberUnformattedString = int2str(nextNumberUnformatted);
        status = status + " Next Number: " + nextNumberUnformattedString + ";";

        status = status + " Getting next number;";
        nextNumber = NumberSeq::newGetNum(numberSequenceReference).num();
        status = status + " Number successfully retrieved;";
    }
    catch
    {
        status = status + "Exception";
    }

    return status;
}

The return value I get from that is:
"Initializing; Getting number sequence reference; Number sequence code: Prod_6; Continuous: Yes; Manual: No; Blocked: No; Next Number: 284; Getting next number;Exception"

Based on what I see in the UI, everything looks like what I would expect (number sequence code and the other properties). I have no clue where to look next. Any ideas?
