XmlExporter fails if a subject cannot be resolved and gives truncated output

-Loris Bennett via grouper-users-
OK, I have found what was causing the trouble. The following was written
to grouper_error.log:

2008-07-04 10:47:05,274: unable to export to xml: No results:
searchSubject searchValue: 332279

Something, probably my fiddling around with sources.xml, had invalidated
some IDs used by search subject. I found several groups, the members of
which could not be displayed, and deleted these. After that the export
worked.

However, this error situation causes the write-operation to fail at a
seemingly random point:

...
<internalAttributes>
<internalAttribute
name='parentStem'>TestFolder:subfolder</internalAttribute>
<internalAttribute name='createSubject'>
<subject id='GrouperSystem' type='application'
source='g:isa'/>
</internalAttribute>
<internalAttribute
name='createTime'>1212134050347</internalAttribute> <!-- Fri May 30
09:54:10 CEST 2008 -->
<internalAttribute name='modifySubject'>
<subject id='GrouperSystem' type='application'
source='g:isa'/>
</internalAttri
(EOF)

which is obviously not desirable. Perhaps somebody can look into this
scenario.
