Description

I've overridden JavaSerializer in the following way. When my application is in development mode, the PageSizeDebugPanel attempts to serialize my components to calculate their size. Unfortunately it does this before detach() has been called, so of course the NotDetachedModelChecker() fails.

JavaSerializer serializer = new JavaSerializer(getApplicationKey()) {
    @Override
    protected ObjectOutputStream newObjectOutputStream(OutputStream out) throws IOException {
        List<IObjectChecker> checkers = Lists.newArrayList(
                new NotDetachedModelChecker(),
                new ObjectSerializationChecker());
        return new CheckingObjectOutputStream(out, checkers.toArray(new IObjectChecker[checkers.size()]));
    }
};
