Mark Proctor commented on JBRULES-2030:
---------------------------------------
I can't recreate this with trunk I made the following unit test, where Cheese exists
and MissingClass doesn't:
public void testMissingImport() throws Exception {
String str = "";
str += "package org.drools \n";
str += "import org.drools.Person\n";
str += "global java.util.List list \n";
str += "rule rule1 \n";
str += "when \n";
str += " $i : Cheese() \n";
str += " MissingClass( fieldName == $i ) \n";
str += "then \n";
str += " list.add( $i ); \n";
str += "end \n";
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newByteArrayResource( str.getBytes() ),
ResourceType.DRL );
if ( kbuilder.hasErrors() ) {
System.err.println( kbuilder.getErrors() );
}
assertTrue( kbuilder.hasErrors() );
}
And i get a resulting printout, and no NPE.
Unable to resolve ObjectType 'MissingClass' : [Rule name='rule1']
Please provide more information on how to recreate this.
