|| > 20)</div><div style="margin: 0px; min-height: 14px;"><br></div><div style="margin: 0px;">Right now, the " - <expression>" put a 'comma' at the end of the line making this:</div>
<div style="margin: 0px;"> p: Person( age == 10, || == 15, || > 20)</div><div style="margin: 0px; min-height: 14px;"><br></div><div style="margin: 0px;">What throws errors...</div><div style="margin: 0px; min-height: 14px;">
<br></div><div style="margin: 0px;"> Is it possible to do that? I love the || == <value> thing in each line...</div><div style="margin: 0px; min-height: 14px;"><br></div><div style="margin: 0px;">Thanks.</div><div>

<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( </span></font><font face="Courier New" size="2"><span style="font-size: 10pt;">
application==true || banker==true || officer==true )<br> then<br> // do something<br> end</span></font></p> <div><p style="margin-left: 0.5in;"><span><font face="Times New Roman" size="3"><span style="font-size: 12pt;">
Drools does NOT inspect object fields... only public methods.</span></font></span><br> <br> <span> 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.

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> <br> []s<br> Edson</span></font></p> <div><p style="margin-left: 1in;">
