Hi All,

I have got 2 entites in the parent child relationship. Whenever parent is persisted, I need to check for its dirty childs. This is because, I need to do some custom processing before dirty objects can be persisted.

Is there any way through which I can determine before hand if an object is Dirty or not. It will be great if there exist any such utility method through which it can be determined if an object is dirty or not without explicitly calling a finder and then to do equality check.

I hope that what Hibernate uses internally must be accessed and using that it can be determined if a particulr object is dirty or not.

Have you tried using an Interceptor ?

Hi,

Yes I tried the adapter. In the case of save, it worked correctly. But in the case of Update, it did not. Actually, I have to change a child collection of the entity which is being persisted. I tried to set a collection on a instance variable of the entity in onDirtyFlush, but it returned a class cast exception. Some digging on the forums mentioned that Hibernate internally saves the collections in one of its own formats.

Can you give me a hint or a link on how I can manage the updates on child collections in the case of onDirtyFlush?


Thanks & Regards,
Nitin
