Description

« Hide

When running the Retrieve class it works fine. But if we comment out createClassTable() and insert(). and call just getEntry() on the database, it returns null values for some fields.

Even for the PEReflectField. get() are not called as expected

Ex: when createClassTable() and insert() are not commented
Output is TestClass , T1, 8, field2

When commented Out put is TestClass , null , 8, null

Rodrigo, any insight into this?
Is the problem with db4o or with Reflector code?

I'm still working on this.

What I'm doing right now is writing a complete test suite for db4o's reflector api based on a hypothetical PersistenceProvider interface which is roughly based on GigaSpaces persistence adapter interfaces.

The test suite will serve two purposes: documenting how to properly write a custom reflector and making sure db4o doesn't break custom reflectors.

It should be available later this week.

We are now providing a complete test case which serves as an example on how to write custom reflector implementations.

The test case can be found under the db4oj.tests project (src/com/db4o/db4ounit/common/reflect/custom/) in our repository.

Further problems or questions will be more productively answered if provided with a patch to the test case.
