> If you specify an invalid dialect attribute in a rule, or as a package dialect then the eclipse plug-in (and also BRMS) reports a java.lang.NullPointerException
> Either one of the two dialect used in the example below causes the NullPointerException:
> package defaultPackage
> import java.lang.Integer;
> dialect "javaxxx"
> rule "Examaple"
> 	auto-focus "true"
> 	dialect " javaxxx "
> 	when
> 		p : Integer( intValue == "10" )
> 	then
> 		retract( p );
> end
> In the BRMS if you try to validate the above rule or build the package you get an error with the stack shown below. It's not really a big issue other than the fact that the error message gives you absolutely no clue as to the cause of the error, or where it is located. It's only when I looked at the source code that I realized it was due to an invalid dialect name.
> An error occurred executing the action. 
> Details 
> java.lang.NullPointerException
>  at org.drools.rule.builder.RuleBuildContext.<init>(RuleBuildContext.java:126)
>  at org.drools.compiler.PackageBuilder.addRule(PackageBuilder.java:441)
>  at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:304)
>  at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:167)
> <More Omitted>
