Maybe Rong can help me, but maybe others also, if Rong is too busy, or
does not read the email
I get all the time in a specific archetype the ErrorType UNKNOW, when I
print the ErrorMap\.

I get it very much on top of the archetype:
\{/\[at0000\]/details\[at0001\]/=UNKNOWN

Is it possible to indicate what this error means\.

I found the enum ErrorType, but it was not documented in the code
However, most of them speak for themselve, but some don't

MISSING, BAD\_INDEX, BAD\_FORMAT, BAD\_VALUE, TERM\_MISSING, UNKNOWN,
    CARDINALITY\_TOO\_FEW, CARDINALITY\_TOO\_MUCH,

I wonder, after CARDINALITY\_TOO\_MUCH is a comma \(,\)
This confuses me, as if there should be another value?
Maybe it is a bit of my Java ignorance, if so, excuse me for that\.

thanks
Bert

Hi Bert,

Sure I can help :\)

I believe this error type is to do with known Reference Model class\.
This exception is thrown by RMObjectBuilder within construct\(\)\.  Method
loadTypeMap\(\) loads all openEHR reference model from the class path so
if you want the builder to support other RM you need to change that\.

Hope this helps\.

Thanks Rong, I left the path of working outsinde the RM Model, and I
already found the exception comes from the RMObjectBuilder\.

But still, I am working on code which is not the latest the greatest\.
But the latest, the geatest is a moving target, and for an application
builder, that is not suitable\.
So I stuck at level 0\.95, and I will upgrade in a few months\. \(maybe the
1\.0\.1 version is stable by then\)

My question is about this particular version\. And there is a small piece
of code which I do not understand, that is where my question is
referring too\.

I guess the exception is thrown where in the RMObjectBuilder the line
leafc\.createObject\(\.\.\.\) is executed\.
But this is an abstract method, so I have to go to the class on which
the error occurs to find out what causes the error\.

So I was hoping, you could give a generally true indication in what
situation the UNKOWN\- error occurs\. If possible\.

And please allow me a stupid question, it is because I still have to get
used to the java\-environment\.

What is the easiest way to turn on the logging in the kernel\-jars?

Recompile it in a version with logging enabled, or can I turn it on in
my local log4j\.properties?

Thanks for your attention
Bert
