Sorry I can't provide the patch to reproduce this. The patch is too big and it's not mine, and I can't isolate the part that reproduces the bug... because of the bug itself.

The issue is that I'm getting somewhere this error:

  value: no method for 'list'

AND when I do Find -> Find last error it says:
  ... sorry, I couldn't find the source of that error.


An untrackable error is always a bug. Source of an error MUST always be trackable. Assuming that the patch is actually sending a list message to an object that is not capable of handling a list (i.e. there is an error in the patch), the fact that it is not tracked is a bug.

ALL places in Pd's code where error messages are generated without properly tracking them so that they can be found in Find -> Find Last error, should be fixed. 
This is a PLAGUE in Pd.


Furthermore, in this case, the error message is also nonsensical on its own.
It is supposed to mean that there is a "value" object that is receiving a list in an inlet that can't handle a list (by the way, it is a one-float-item list that is being sent, so it's actually a float). Now, [value] has only an inlet, and it _can_ handle lists and floats, so the message doesn't make sense. Clearly, it is not being issued by a [value] object, but then why does it say "value:" ?


And by the way, it's about time to implement the possibility to find all errors, not only the last one.
