data type mismatch - IMAGE object

[Martin Maguth]

i believe the issue occurs when the existence check for the object fails
for some reason. the method for IMAGE.existencecheck checks the link table,
workitems, the archive system as well as other areas to verify whether an
image with the corresponding key. sometimes, when system performance is
VERY bad, the method cannot process the database checks quickly enough and
can end with an errror that is incorrectly "announced" with the error
message you list below ... the dependency on system resources could explain
the sudden and sporadic occurence of this problem ...
 
i hope this helps.

Subject:  data type mismatch - IMAGE object
 
 
 
We have a 4.5b system where we use archivelink functionality in a custom
workflow.  One of the initial steps of the workflow is to instantiate the
IMAGE
object.
 
Recently, we have had 10 work items, all from the same day, that could not
execute this step in the workflow.  The message (WL 109) states the
following:
 
"According to the container definition, expression references an object of
type
u.  However, the element to which this expression is allocated is defined
with
Dictionary reference IMAGE."
 
This is the only time we have known this to happen.  It has worked
successfully
for thousands of other work items.
 
>> What is type "u"?
>> What could be causing this problem?
>> Do you have any tips on how to troubleshoot this further?
 
Thanks,
Brian
