I would like to know why the fme_feature_type attributes is removed after passing the lines features through areaBuilder transformer inserted inside a custom transformer.
Even more weird, just after areaBuilder, Im doing a FeatureMerger to restore all attributes to each feature as they were before going through some transformers, but only fme_feature_type is not passed.

Anybody may provide explanations on this?
Thank you,
