There are 2 important concepts related to time
windows. First and most important, sliding windows only work in STREAM_MODE,
not in CLOUD_MODE (default). Did you set the engine to STREAM_MODE?<br>
Second, the session clock becomes really important in
STREAM_MODE: what clock are you using? Real time or pseudo clock?<br>

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. >From the Fusion features description,

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" target="_blank">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>
