Hello there! I'm facing a really annoying problem here. I have table with a CLOB column mapped to a String property on my class.
At the beginning I had problems persisting it, due to batch size, so (as shown above) I've it set to 0.
I have no problems persisting it, but when I try to update the entity, when the String is over a certain limit (could not find how many chars :( ) Hibernate ignores the value and is setting the column as null. I've tested it several times, and happens only for big strings (not that big actually, I believe over 4096 chars)
It is possible to check at the log, that hibernate seems to be skipping one column (there's no binding for column #2):
