Hi all. I have a very peculiar issue with Jess, latest version.
I have a defquey is-cell-open which retrieves from a list of templates Cell the
ones matching the parameters given. When I call it passing the parameters as
constants, it works, but when I pass them as variables it fails, albeit the
variables have the same values as the parameters. Here is a copy-paste of the
Shell. Can anyone suggest me where to start for fixing it?
Thank you all,
