Hi,<br>
<br>
How do I compare two fields in a decision table e.g.<br>
transactionDate==attachmentDate<br>
<br>
I can create a rule that has a restriction using two fields such as<br>
<br>
rule "check if risk is active"<br>
when<br>
$risk : Risk(transactionDate==attachmentDate)<br>
then<br>
...<br>
end<br>
<br>
I can do this using an eval statement in a decision table<br>
<br>
Condition<br>
$risk:Risk<br>
eval($risk.getAttachmentDate().equals($risk.getTransactionDate()))<br>
<br>
How do I write this without an eval?<br>
I want to write something similar to the rule above:<br>
<br>
Condition<br>
$risk:Risk<br>
attachmentDate == transactionDate<br>
<br>
Thanks<br>
David<br>
