<br> Saleem,<br><br> For sure, your mapping must have some typo or mistake. A rule like this works and is correct:<br><br>rule XYZ<br>when<br> ObjectA( <font face="Courier New" size="2"><span style="font-size: 10pt;">
application==true || banker==true
|| officer==true )<br>then<br> // do something<br>end<br></span></font><br><div><span class="gmail_quote"> Drools does NOT inspect object fields... only public methods.<br><br> If you are using a DSL, make sure your "drl" file is named "dslr" (this is new in
4.0), so when you open it in eclipse, you have a tab that shows you the result of the DSL template processing. This way you will be able to see any eventual mapping mistake.<br><br> []s<br> Edson<br><br><br>2007/8/21, Saleem Lakhani <

Drools respects encapsulation, so it works with javabean method
name conventions. If you have a method isApplication() that returns a boolean,
does not matter how your class calculates the return value. Same for any other
method. In 4.0, you can write:<br>
<br>
ObjectA( application == true || banker == true )<br>
<br>
To map that as a DSL, just follow your usual procedure and syntax.<br>
