In the actions_summary of a specific topic json response, there are some fields: acted, canAct, canUndo and canDeferFlags. I can’t find any documentation as to what they actual mean.
When I click on a “like” button for example, the acted is true, along with the canUndo. At some point the canUndo is false, but the acted remains true. What action makes the canUndo go false? What actions make these flags get set or unset?
