Here is the error:
Server was unable to process request. ---> MBException: Error in CMBVariant:

perator MB:

ataValuePtr(). Type of the variant not specified - cannot convert to datavalue. (0x80040500)
It comes from this call:
getMyStub().reviseAssetMetadata(movedAssetID,(new ArrayOfMBMetadata(mergedDBMetadata)));
It used to work before

Thanks.
