Expert+Fusion and that was my understanding as well and I have been reading
through the docs on that links, however I have not read all of the documentation
exhaustively yet. There doesn’t seem to be a lot of samples(syntax
wise) for authoring rules taking advantage of those Fusion features.
There are isolated one or two line samples, but I guess I am having a difficult
time determining how to author rules based on collections of data…think
of sensor data over time….so I want to author rules that work on the
latest readings plus some configurable amount of readings in the past.

nuts and bolts of implementing it is eluding me thus far. <o:p></o:p></span></font></p>

Chris,<br>
<br>
Fusion is an extension of Drools Expert. Think about it as all
Expert features + some additional features. That is why Drools Fusion docs is
just a list of features explained.<br>
<br>
I assume you looked here already:<br>
<br>
<a href="http://www.jboss.org/drools/documentation.html">http://www.jboss.org/drools/documentation.html</a><br>
<br>
For both, expert and fusion docs.<br>
<br>
So, back to your rule, syntax seems correct to me. Why do you say
it is not working? What error or symptoms do you see?<br>
