We have an inserted fact in the working memory containing a list of objects that we need to apply the rules on in the condition column. I am not able to find the correct syntax for expressing this requirement in the spreadsheet using the "from" conditonal element.
As an example, Person p in inserted in the working memory and p.getAddresses() returns a list of Address objects that we need apply some rules on along with some rules on p.
Any other known ways of achieving this in xls are also welcome.
