Hmmm. While trying to create a unit test method for you (for the latest version from CVS), I wrote the following method (added to ExplicitVersionsTest): | Node root = cache.getRoot(); | | TestVersion lev2V = new TestVersion("Lev2-v"); | cache.getInvocationContext().getOptionOverrides().setDataVersion(lev2V); | root.addChild(Fqn.fromString("LEV2")); | | Node lev2 = root.getChild(Fqn.fromString("LEV2")); | | TestVersion lev3V = new TestVersion("Lev3-v"); | cache.getInvocationContext().getOptionOverrides().setDataVersion(lev3V); | lev2.addChild(Fqn.fromString("LEV3")); | | Node lev3 = lev2.getChild(Fqn.fromString("LEV3")); | | if (lev3 == null) | throw new Exception("Hay! lev3 is null!"); | | TestVersion lev4V = new TestVersion("Lev4-v"); | cache.getInvocationContext().getOptionOverrides().setDataVersion(lev4V); | lev3.addChild(Fqn.fromString("LEV4")) | The null check for lev3 was added because it is indeed null and the test fails because of that; that seems strange, and was not the behavior I was trying to reproduce... After commenting out the explicit-versioning related code, everything seemed to work normally; lev3 was not null... | Node root = cache.getRoot(); | | // TestVersion lev2V = new TestVersion("Lev2-v"); | // cache.getInvocationContext().getOptionOverrides().setDataVersion(lev2V); | root.addChild(Fqn.fromString("LEV2")); | | Node lev2 = root.getChild(Fqn.fromString("LEV2")); | | // TestVersion lev3V = new TestVersion("Lev3-v"); | // cache.getInvocationContext().getOptionOverrides().setDataVersion(lev3V); | lev2.addChild(Fqn.fromString("LEV3")); | | Node lev3 = lev2.getChild(Fqn.fromString("LEV3")); | | if (lev3 == null) | throw new Exception("Hay! lev3 is null!"); | | // TestVersion lev4V = new TestVersion("Lev4-v"); | // cache.getInvocationContext().getOptionOverrides().setDataVersion(lev4V); | lev3.addChild(Fqn.fromString("LEV4")) | Am I using the API incorrectly, or is this indeed a bug? I didn't yet manage to reproduce the same bug, but perhaps this is related... I guess in our application some other factor also takes a role in the failure.
