How to cascade comments in linked cards in Trello

[Shyam Reyal]

I have two mirrored cards (say ONE and TWO) on two boards. ONE has a checklist "Mirrors", which contains a link to TWO.

This rule is setup on board containing ONE:

when a comment is posted to a card by anyone, for each card linked from an item in checklist "Mirrored Boards", post comment "Comment by {username} on {date} {time24}: {commenttext}"

However it does not work. I've attached some screenshots.

@Shyam Reyal The checklist is named "Mirrored Boards", not "Mirrors"

@Iain Dooley sorry my bad it was a typo when I copied the actual butler rule to this question. Regardless, it still does not work :( 

[Iain Dooley]

@Shyam Reyal these don't appear to be on the same board, have you installed the command on the board where the card containing the Mirrored Board checklists resides?

[Shyam Reyal]

@Iain Dooley no it wasn't installed. I just installed it right now, and tried again. Still the comment doesn't cascade :( 

[Iain Dooley]

@Shyam Reyal okay well I just created the same command and it works:

@Iain Dooley 

Were both your cards on the same board?

[Iain Dooley]

@Shyam Reyal no I set them up on separate boards to get as close as possible to your setup

[Shyam Reyal]

@Iain Dooley  this works for me if its on the same board for me, but not if they are on separate boards. I ensured the command is enabled on both boards.

Let me try a different two boards just to be sure.

Hi @Iain Dooley you are correct. when I moved the mirrored card to a different board, it worked. So it seems the block exists between two specific boards only.

Hi @Shyam Reyal ,

As per as my information you can't copy the comments automatically on linked cards you have to do it manually.

Hi @Soumyadeep Mandal thanks for replying. This cascading works in other operations such as card moving. e.g. 

when a card is moved into list "Done" by anyone, for each card linked in the attachments, check item "{triggercardlink}", and post comment "Dependency {triggercardlink} was completed on {date}"

This works perfectly.  In this case, when the master-card is moved to Done, all the dependent cards get marked with a comment. This doesn't work only when the trigger itself a comment being posted on the master-card. Do you know why?

Hi @Shyam Reyal ,

This is how Trello works. There are some limitations in Trello regarding comments and Trello is updating new features regularly.
