I am trying to research using a rule template driven by data from a spreadsheet, rather than using a straight decision table.<br><br>I understand I need to use the ExternalSpreadsheetCompiler but am finding a distressing lack of information about the template format.<br>
<br>The 5.0 docs seem to have mistakes; the code example for that section looks to have been cut &amp; pasted from another section and does not match the text description of what is going on.<br><br>Using google, the best I could find was a blog posting from Steven Williams on Aug 26, 2008: <a href="http://blog.athico.com/2008/08/drools-rule-templates.html">http://blog.athico.com/2008/08/drools-rule-templates.html</a><br>
<br>In this blog posting, he said it was the first of 3 examples from the drools-examples project. But I could not find any additional blog postings by him on this subject.<br><br>Does anyone know of additional documentation or examples on how rule templates work?<br>
<br>Specifically, how to do optional columns, and array columns, similar to how the built in decision tables feature works?<br><br>Adam<br>
