The next method cannot be invoked in method 'initValue' because it's not a Chain Of Command Method

Trying to extend initValue method on CustCustomerV3Entity. The goal is to auto-generate customer account number when customer record is inserted via the data entity.

I'm not clear why CoC isn't working. Even though CustCustomerV3Entity doesn't implement this method, it still inherits it from Common. This should work according to

docs.microsoft.com/.../method-wrapping-coc

What are my options? The only other option I can think about is creating my own data entity but this seems to be a huge overkill.

Here's the code I'm trying to use

[ExtensionOf(tableStr(CustCustomerV3Entity))]
final class CustCustomerV3Entity_Extension
{
    public void initValue()
    {
        next initValue();

        if (!this.skipNumberSequenceCheck())
        {
            NumberSeqRecordFieldHandler::enableNumberSequenceControlForField(
                this, fieldNum(CustCustomerV3Entity, CustomerAccount), CustParameters::numRefCustAccount());
        }
    }

}

Forgot to update you guys - this was turned out a bug in PU21 that Microsoft acknowledged and fixed in PU22.

Unfortunately I don't know the answer, so you have to try all of them ( events) to see if there is suitable one. If you wouldn't find any you have 2 options:

easy one, to duplicate entity and add code wherever you need or open extensibility request to ask MS to make it extensible. But it could be rejected just because you have easy work around - duplicate entity or because there is a deal for extensibility requests...

Ievgen, I see what you mean now.

Question here - is this something Microsoft aware of and will be fixing in the upcoming releases? According to the wiki, it should be possible to CoC methods that are not overriden in a specific class. I don't see why this should not be working on data entities.

In regards to this particular case, unfortunately I don't think your solution will work. The NumberSeqRecordFieldHandler must be initialized in the initValue before the call into the base method. This is because enableNumberSequenceControlForField method establishes certain event subscriptions, most importantly a subscription to onInitializingRecord. If I call NumberSeqRecordFieldHandler::enableNumberSequenceControlForField inside the onInitializingRecord, it will subscribe but will never be called. If I had another event that fires before onInitializingRecord, I could try that but I think onInitializingRecord is the first available event in the sequence of data entity execution.

I was actually talking about events you have, like InitializingEntityDataSource or InitializingRecord, try one of them. Your way with extension works only if entity has this method but unfortunately it is not defined for CustCustomerV3Entity

Thanks ievgen!

I'm on PU21. Is there anything specifically that I need to enable? I have just rebuilt all models but that did not make any difference.

As for event handlers, I thought about it but I don't believe I can use them. initValue() is not overriden by the CustCustomerV3Entity so I don't think I can attach an event handler.

Hi Venkatesh,

Thank you for your response!

I'm on PU21. I compared the syntax of your sample against what I have and it's the same with the exception of tablestr() vs dataentityviewstr(). I tried this but it didn't make any difference. The compiler is still complaining about me using the next() call,

To get CoC on data entities you need to install PU mentioned above, but you can always use event handlers to achieve the same if CoC does not work for you.

Hi Alex,

Enable Chain of Command for data entities from Platform update 20 and the syntax follows.

docs.microsoft.com/.../platform-extensibility

[ExtensionOf(dataentityviewstr(CustCustomerV3Entity))]

final class CustCustomerV3Entity_Extension

{

public void initValue()

{

}

}

Thanks,

Venkatesh
