Joining and Nesting Markers:

Verb[causative[て]] - means て form of the causative form of the verb.
[AものをB, similar to のに, is used to express that something happens contrary to expectations. However, it emphasizes displeasure, criticism, or regret towards the listener more strongly and is considered more formal and old fashioned than のに.]
[Also, unlike のに, there usually is a condition in A, which if only had been realized, B would not have happened. Therefore it is generally not used in “despite the fact” type of sentences (毎日走っていたのに重量を負けない）. B can be omitted]
[Remember that ものを can also be used as a noun meaning “thing” with direct object particle]
