<br> The loop problem is not related to the rule format. I.e., if you have a loop in the decision table, you will have it on drl rules too, etc.<br> There are mechanisms to avoid undesired loops, like no-loop and lock-on-active rule attributes, but usually it is just a matter of refining your rule declarations.<br>
<br> Regarding the update() call, once you understand how it works, you may decide not to use it in some cases, but the original description for your problem clearly states what happens when update is not used properly.<br>

<div><font face="Arial" size="2">Thank You for your reply!</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">I have already added the "Update()".</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">I added it in the ACTION column following the
column</font></div>
<div><font face="Arial" size="2">where i set the "upronto" field.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">But then it produces an infinite Loop!</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">It updates the upronto and the rule fires
again....</font></div>
<div><font face="Arial" size="2">so the infinite loop starts!</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Should I avoid using decision tables?</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Should I use a sequential algorithm instead of

<div><br></div><br> I don't know about your ruleflow
question, but you seems to be missing an update() call that will cause exactly
the behavior you are describing:<br><br><font size="2">
<p align="left"><em></em></p>
<p align="left"><em>when</em></p>
<blockquote dir="ltr" style="margin-right: 0px;">
<p align="left"><em>cw: ContractWrapper(mycontract.serviceDetail.pronto ==
"Y", mycontract.serviceDetail.pronto == "Y")</em></p></blockquote>
<p align="left"><em>then</em></p>
<blockquote dir="ltr" style="margin-right: 0px;">
<p align="left"><em>cw.setUpronto(Pronto.Y);</em></p>

<---------</span><br></em></p>
<p align="left"><em>System.out.println("PS1"+cw.getMycontract().getId());</em></p></blockquote>
<p><em>end</em></p></font><br> Without the update call, the
LHS of the rules will never see the attribute change. This is expected
behavior.<br> The RHS of the rules always see the actual
attribute values though, since shadow proxies are only used in
LHS.<br><br> []s<br> Edson<br><br>
