[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1170) ClassCastException using dynamic salience

ClassCastException using dynamic salience ----------------------------------------- Key: JBRULES-1170 URL: http://jira.jboss.com/jira/browse/JBRULES-1170 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.1 Reporter: Yuri de Wit Assigned To: Mark Proctor Fix For: 4.0.2 I have the following dynamic salience: salience ( -10000 / (c.size * t.size) ) that throws a ClassCastException when c.size * t.size is an odd number: java.lang.ClassCastException: java.lang.Double at org.drools.base.mvel.MVELSalienceExpression.getValue(MVELSalienceExpression.java:33) I then tried: salience ( (int)-10000 / (c.size * t.size) ) or salience ( (int)( -10000 / (c.size * t.size) )) But got a MVEL error compiling the expression. The solution I found was to use a function: salience ( -1 * FN.priority(c.size, t.size) ) Note that I had to use "-1 *" because just "-" gives me a MVEL error compiling the expression.
