Greetings ladies and gentlemen,
I am running to a bit of trouble with a section of a my model as I
am testing through D2W. I am coming up with an Illegal State
Exception that reads as follows:
java.lang.IllegalStateException: sqlStringForKeyValueQualifier:
attempt to generate SQL for
com.webobjects.eocontrol.EOKeyValueQualifier
(dataReductionSources
._eofInv_DataReductionScalar_dataReductionSources.id = 21) failed
because attribute identified by key
'dataReductionSources
._eofInv_DataReductionScalar_dataReductionSources.id' was not
reachable from from entity 'PhotoSource'
I am having a hard time matching the names in that up with your model
diagram. It is trying to determine the join conditions needed for the
qualifier and can't get from A to B based on the information in your
model and its best guesses.
Look at the relationships between DataReductionScalar and PhotoSource.
What is the qualifier?

The section of my model that this pertains to looks as follows:
<PastedGraphic-2.pdf>
I am at a bit of a loss to make sense of why this error is cropping
up. Any ideas?
Thank you,
