[rules-users] RE: Problems with Decision Table

[helidesai]

Hi Jeff,

Thanks for your reply. I put eval(obj1.getDateField().before(new Date()) ==
$1) in CONDITION column. But Rule engine just ignore this rule and doesn't
display anything in DRL. I think may be because I have not put any value in 
data field. What value should I put in data field ? 

I think eval returns true or false? I have read in manual but couldn't
understand its use.

I just want to check that  if Obj1.getDateField().before(new Date())  == 
true  then print msg. so $1 can be true or false. But when I put "true" or
"false" in data field, it gives error.

Please let me know about this. 

Regards,
Heli.
