Re: [rules-users] "Not exists" on at least one element from the set
I don't think you can unfortunately.
You've got a number of options:
1. define a global (in sheet headers) and insert the actual values from code (perhaps
reading from the spreadsheet).
2. Define a custom datatype "Name", have a table with which each row inserts a
Name object with associated value and then use it in your when clause like any other
fact.
3. Have a separate row for each name, use activation groups or inserting a lock/latch
object, or insert logical chaining so that the then part is only executed once.

Subject: Re: [rules-users] "Not exists" on at least one element from the set
Thanks for the fast response.
I am using excel decision tables and can't set globals with values from the
cells.
I can only use brown fields and through $param refer to the contents of the
cell.
That leads me to a question.
Can I define $collection in the when statement?
something like this:
when
exists (
$name: String from ('a','b','c')
not Object(name == $name)
)
then
Much obliged.
