If a map a subclass that contains a bag of sibling subclasses, I get a ClassCastException. Debugging this it appears that someow the CollectionEntry key is being initialized to the base class rather than the appropriate compisite key.

See mapping/code below. If there are no suggestions, I will submit this bug and test case to JIRA.

Thanks,
Mark

I am not an expert, but you have not supplied a type in the property of the map file.

<key-property name="key1" column="colKey1" type="string"/>

Mike,

That's certainly a good suggestion, I have tried that and still the same error. I beleive that the ClassCast is actually the key itself, not the attribute. In this case I believe its trying to cast org.hibernate.test.subclassbagofsibling.BaseDocument to org.hibernate.test.subclassbagofsibling.DocumentKey.

I'm having what I believe is this exact problem. I'm new to hibernate and thought that maybe I was getting something wrong, but from everything I've read, I'm doing everything correct and hibernate is making a mistake.


I have 4 classes:

----------------------


----------------------

----------------------

----------------------

The classes are mapped thusly:

Question.hbm.xml


---------------------------------

Response.hbm.xml


--------------------------------


It seems reasonably straightforward, I think.

You can see that in the "Question" implimentation, I added the generics code "Response<T extends Question>" to try and force hibernate to make sure that the type of "SliderResponse.getQuestion()" would be "SliderQuestion". Indeed its not actually possible for code that doesn't set the "question" value as a "SliderQuestion" to compile!

But when I run the following:



I get the output:



As you can see, hibernate is returning an Instance of Question, rather than SliderQuestion, my generics code is actually making "r.getQuestion()" fail because its returning the wrong type!

If I remove the line to get the following test code:


Then it will execute fine, the call to "getSliderAnswer" works fine (even though SliderAnswer is also a subclass of Answer).


I'm pulling my hair out over this, I think the problem lies in the fact that I have defined the <many-to-one> relationship using the Question class, but my understanding is that hibernate should handle the polymorphism and return me the true Type of the object that was originally saved.
So either there is a mapping subtlety that I haven't discovered yet, or this is a bug in hibernate.


I apologise for the length of this response, but I see you only posted this a few days ago, and I'm hoping that we can help each other out here.
