Thanks for your quick response Michael, I have identified the issue.. while writing rules in Decision table (Web-guided editor) -> column configuration there is a option Update engine with changes (Checking this will tell the engine that the value has changed. This will cause the rules that depend on it to be re-evaluated. Use with care!). This was checked unintentionally, hence every time it is going to the same rule.

"Infinite loops" normally imply there is some degree of circularity between rules. Can you please provide a self contained test case or your rules (DRL form, preferential). Thanks 2011/3/10 Sartaj Shaik <sartaj.shaik(a)tcs.com&gt; Hi, I have written some rules in Decision table (Web-guided editor), and I have implemented the AgendaFilter to fire rules that ends with the rule name specified (EndAgendaFilter) here is the accept method I have written. When I fire the rules ends with some "XXXXX", this accept method goes into infinite loop and my Sysout prints "Rule 1 XXXXX" infinite times. (Note: all the condition variables that i have passed to guvnor matches with the first row of that rule, hence getting Rule 1 XXXXX) public boolean accept(final Activation activation) { System.out .println(activation.getRule().getName()); if (activation.getRule().getName().endsWith(this. suffix)) { return this.accept; } else { return !this.accept; } } All my other rules are working fine, even I have created the same rule again (same conditions, actions, data etc) it is working properly. Don't know what is the root cause, any ideas? I have 3 similar rules which are failing, and those rules contains lot of rows, so can't create the new rules for those again to make them work :( Please help!!! =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
