<div>Hi guys,</div><div><br></div><div> we are currently working with Drools Fusion in order to build a complex event processing solution. We've modelled our events using and object (Event) and this object is shared with everyone that needs to publish and event. </div>
<div><br></div><div> Our scenario goes this way</div><div><br></div><div>1) Our shared class, located in <b>ar.com.fluxit.Event</b></div><div><br></div><div>2) An example of our cep rules declared in package <b>rules.flux</b></div>
<div><br></div><div> package <b>rules.flux</b></div><div><div><br></div><div> import <b>ar.com.fluxit.Event;</b></div><div><br></div><div> declare <b>Event</b></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>@role (event)</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>@expires(1m)</div><div> end</div><div><br></div><div><div> rule "hello world"</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>when</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span> $event:Event( eventName == "Hello World") from entry-point "<b>rules.flux</b>"</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>then</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span> System.out.println("Hello world");</div><div> end</div></div><div><br></div><div><div><br></div></div><div>3) When we try to insert a <b>ar.com.fluxit.Event </b>as a fact in entry point "rules.flux" Drools Fusion throws a NullPointerException. If you read Drools Expert documentation (<a href="http://docs.jboss.org/drools/release/5.2.0.Final/drools-expert-docs/html/ch05.html#d0e3661">http://docs.jboss.org/drools/release/5.2.0.Final/drools-expert-docs/html/ch05.html#d0e3661</a> - </div>

<div><a id="d0e3661" style="color:rgb(51,51,51);font-family:'Lucida Grande',Geneva,Verdana,Arial,sans-serif;font-size:12px;line-height:18px;text-align:justify">"The first important thing to realize is that a declared fact will belong to the package where it was declared. So, for instance, in the example below, <code class="code" style="font-size:0.9em;font-family:courrier,monospace;white-space:nowrap">Person</code> will belong to the <code class="code" style="font-size:0.9em;font-family:courrier,monospace;white-space:nowrap">org.drools.examples</code> package, and so the fully qualified name of the generated class will be <code class="code" style="font-size:0.9em;font-family:courrier,monospace;white-space:nowrap">org.drools.examples.Person</code>."</a></div>
<div><br></div><div>When we change package declaration to <b>package ar.com.fluxit </b>everything works like a charm. But in our cep scenario we need that our ar.com.fluxit.Event object to be user by all rules declared in any package. </div>
<div><br></div><div>So, there goes the question. There is a workaround for this? This is a bug? </div><div><br></div><div>Any help would be very appreciated</div><div><br></div><div><br></div><div>Cheers</div><div><br clear="all">
