Krishnan,
May I ask you please to open a JIRA and attach your examples bellow? It
seems to be a bug...
As a workaround, while we fix it, use primitive booleans and it shall
work...

Hi All,
I am using the 4.0.M2 version of jboss rules.
public class Device() {
private Boolean isCiscoVersion;
private Boolean sysNamePresent;
private Boolean isPixVersion;
}
When I write the rule as follows :-
rule "Cisco PIX Device"
when
d : Device ( isCiscoVersion == null,
sysNamePresent == true,
isPixVersion == true )
then
System.out.println("This is a cisco pix device.");
end
The rule works. However, when I write the same rule as
rule "Cisco PIX Device"
when
d : Device ( isCiscoVersion == false,
sysNamePresent == true,
isPixVersion == true )
then
System.out.println("This is a cisco pix device.");
end
It even fails to compile and add the rule into the package. Not sure what
is going on ?.
Following is the error I keep getting :-
java.lang.NullPointerException

Any ideas why this is happening ?.
