Hi,<br><br>

<p class="MsoNormal">we were using drools engine 5.0.1 version with rules having &#39;duration&#39;, &#39;agenda-group&#39; attributes and now we want to upgrade drools engine to 5.1.1 or latest 5.3.0 but we find &#39;duration&#39; feature not working. What are the equivalents of those features in 5.1.1 and in 5.3.0?</p>

<p class="MsoNormal"><br></p><p class="MsoNormal">From drools-expert document, &#39;duration&#39; seems as deprecated with &#39;timer&#39;. But even &#39;timer&#39; is not working. Putting &#39;timer&#39; attribute as:</p>

<p class="MsoNormal"><br></p><p class="MsoNormal">rule &quot;test timer attribute&quot;<br>    agenda-group &quot;enrichment&quot;<br>    auto-focus true<br>    no-loop<br>    salience 140<br>    timer ( int: 5s )<br>    //duration ( 5000 )<br>

    when    <br></p>         

......<br>   then<br>         ......<br>   end<br><br>gives &quot;Error: java.lang.ArrayStoreException&quot; Drools compilation error. &quot;timer ( 5s )&quot; compiles, but the rule never fires. <br><br>We are also planning to use @expires in declare. But facts are not seems to be expiring. <br>

<br>What am I missing here? What are the equivalent for &#39;duration&#39; in 5.1.1/5.3.0 and how to use @expires in declare?<br>Please point us to some sample rules that uses these semantics and are working.<br><br>Thanks in advance,<br>
