<div dir="ltr"><br> Allen,<br><br> There is a technical explanation behind that and we never had the time to find a way to overcome this limitation. What you can do, although not ideal, is to send the global as a parameter:<br>
<br>funcion void foo( Logger log, String cond ) <br>{<br>...<br>}<br><br>rule XYZ<br>when<br>then<br> foo( log, someString );<br>end<br><br> If you or anyone would like to help improving this, let us know and we can discuss ways into doing it. <br>

<div><font size="2">There's probably an easy explanation for this. I was wondering about why functions inside of rule files can't access globals?</font></div>
<div><font size="2"> </font></div>
<div><font size="2">For example, I have a log4j logger that I pass into my rule files via a global. The logger should never be a part of working memory. It's just there to capture valuable feedback.</font></div>

<div><font size="2">}</font></div>
<div><font size="2"> </font></div>
