<p>Hello Xiaoshu,</p>
<p>thank you for the information.</p>
<p>At this moment, it looks like a bug in midPoint for me. The
reason is that midPoint has all the information it needs to
determine the shadow name (pid = 017). Most probably the
definition of the shadow is incomplete at that particular moment:
if the primary identifier (pid) would be correctly marked as such,
midPoint would use it as the shadow name.</p>
<p>The exception itself is really harmless here, and all it does is
the pollution of the logfiles (which is, of course, ugly). At
least I think so now.<br>
</p>
<p>Overall, this would deserve logging a JIRA issue, with the
type=bug, and all the necessary details (see <a
moz-do-not-send="true"
href="https://docs.evolveum.com/midpoint/reference/diag/creating-a-bug-report/"
class="moz-txt-link-freetext">https://docs.evolveum.com/midpoint/reference/diag/creating-a-bug-report/</a>).</p>
<p>We would be happy to fix that, but ... you know ... according to
priorities (subscribers' bugs first).</p>
<p>Nevertheless, I hope you will be able to continue with your work.</p>
<p>Best regards,<br>
</p>

<p>That's great. I am now not sure - have you implemented a
(limited) executeQuery method that would allow midPoint to
fetch your resource objects "by UID"?<o:p></o:p></p>
<p>Also, I become more and more interested to see the stack
trace of the "SchemaException" you mentioned. :) I would like
to know the path between points 3 and 4 in your description
below, i.e. creating an object and trying to determine its
name.<o:p></o:p></p>

<p>Hello Xiaoshu,<o:p></o:p></p>
<p>OK, I understand that you cannot execute a "blank" query
that would return all objects on a resource. But can you
execute - at least - a query for one specific object,
identified by UID?<o:p></o:p></p>
<p>--<o:p></o:p></p>
<p>Just by the way, could you share the whole stack trace of
the "SchemaException: Could not determine shadow name"? I am
quite interested in the whole execution path there. And, the
exact midPoint version.<o:p></o:p></p>

<p>Hello Xiaoshu,<o:p></o:p></p>
<p>I am still not sure I completely understand your use
case, but maybe the simplest thing your connector can do
is to mirror __UID__ to __NAME__ itself (if the name is
not known). This is actually what many connectors do.<o:p></o:p></p>

https://docs.evolveum.com/connectors/connid/1.x/connector-development-guide/#__uid__-and-__name__-are-the-same</a>.<o:p></o:p></p>
<p>I am not sure why both of these are obligatory in ConnId
(originally ICF, then OpenICF).<o:p></o:p></p>
<p>The <span style="font-family:"Courier New"">ShadowUtil.determineShadowName</span>
method is maybe not very consistent, I must admit. (I have
looked at it right now.) For example, it is called from a
couple of places in midPoint, and a caller usually catches
SchemaException, and continues with "no name" situation. I
am not sure about your specific situation, because I don't
know exact midPoint version, whole stack trace, and so on.
But I think the best you can do is simply to return both
__UID__ and __NAME__ from your connector, and (hopefully)
midPoint will be happy with it.<o:p></o:p></p>

understand the rational under this as the
connector.create() is meant to create a remote
resource as opposed to create the shadow account, (I
guess is mirrored by the connectorObject). Upon
receiving the UID, the midpoint then creates a
matching shadow account with it (due to the absence of
it). However, as both __UID__ and __NAME__ are *<b>required</b>*
