<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> I have a simple rule as following:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>import
java.util.HashMap;<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'><o:p> </o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>rule
"first"<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>when<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> a
: CrestelRuleModel( $hmap : singleHashMap!=null);<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>then<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> System.out.println("Old
Map: " + $hmap);<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> HashMap
mapp = new HashMap();<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> mapp.put("hello",
"world");<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> a.setSingleHashMap(mapp);<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> System.out.println("New
Map: " + a.getSingleHashMap());<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'> update(a);<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>end;<o:p></o:p></span></b></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I invoke the rule from my client, the rule is executed <b>infinitely</b>.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, I have placed a “<b>drools.halt()</b>”
before “<b>end</b>” statement of above rule. So, it stopped executing
infinitely as I wanted. But <b><i>is it a good practice?</i></b><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Now, I want my input to be filtered by <b>two rules</b>, so
I have placed rules like following:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Courier New"'>import

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But in above case, <b>only the “second” rule executes</b>.
What to do in order to execute both the rules without any infinite loop?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Kindly share some pointers on this. Thanks.<o:p></o:p></p>
