Major Description
Currently the source is generated lazily only once, but once it is set it will not automatically be reset. I think it makes sense to automatically reset the underlying source whenever some write operation is called on the DefaultWorkspaceFilter, i.e. one of
- add(...)
- addPropertyFilterSet(...)
- load(...)
Both setImportMode(...) and setGlobalIgnored(...) do not affect the serialization and therefore do not need to be considered here.
