[ome-devel] Hibernate PropertyAccessExcpetion when creating WellSamples in 4.0.1

[Bernhard Holländer]

Dear developers,

I've migrated my client sources from 3.1 to 4.0.1, which went rather
smoth, but I have a problem with the creation of WellSamples. The
following code that worked in 3.1 yields a Hibernate
PropertyAccessException (pasted below) when working with the 4.0.1
library:

# python code, given are WellI and ImageI objects fetched from the db
ws = WellSampleI()
ws.well = WellI(well.id, False)
ws.image = ImageI(image.id, False)
ws.timepoint = rint(timepoint)
ws.posX = rdouble(posX)
ws.posY = rdouble(posY)
ws = self.updates.saveAndReturnObject(ws)

Here's the exception thrown by the saveAndReturnObject call:

<snip.... python traceback>
   552         ws.posX = rdouble(posX)
    553         ws.posY = rdouble(posY)
--> 554         ws = self.updates.saveAndReturnObject(ws)
    555
    556         l = ScreenAcquisitionWellSampleLinkI()

    serverExceptionClass = ome.conditions.InternalException
    message =  Wrapped Exception:

nested exception is org.hibernate.PropertyAccessException: Exception

}

Is this a problem in the server lib, or do I have to change the way
how I create the WellSample?

Thanks for help! Bernhard
