Hi Anthony, Probably we will implement this in the future, but for now you have to do the query on the comments and then manually traverse the relationship.
Current LiveQuery implementation still needs some optimizations, query de-duplication is one of these ;-) Thanks Luigi 2016-10-19 21:37 GMT+02:00 Anthony <[email protected]>: > I suppose it would be difficult to track changes on comment updates, as >>>> there are no links from comments to posts.
