Switching between design and source view causes errorHandler configuration to change and become invalid

See

The issue can also be in the Camel model where the error handler is modelled with options which are "default" values and not applicable for the given error handler type.
I will have to check the Camel codebase for this in camel-spring and camel-blueprint.
