Re: [rules-users] SPREADSHEET DECISION TABLE: Can I use functions into CONDITIONS?
Hi again! sorry for the delay, I have been out of the office. Thanks all for
the answers. The function I tried to use on my spreadsheet was:
function boolean isInRange(Date date, int months){
Date minDate = new Date();
Date maxDate = Utils.addMonthsToDate(minDate, months);
if((Utils.compareTo(minDate, date) == Utils.EQUAL ||
Utils.compareTo(minDate, date) == Utils.LOWER) && (Utils.compareTo(maxDate,
date) == Utils.EQUAL || Utils.compareTo(maxDate, date) == Utils.GREATER))
return true;
else return false;
}
Utils is a static class I imported from my java classes. From the table
rules:
CONDITION
customer:Customer()
eval(isInRange(customer.setContractEndDate(),$param))
And the trace:

Some suggestion? Thanks again.
