My Code has the following Hierarchy. I am facing some problem, while I try to remove the Child level class object in .dsl file level. Class1: public class Class1{ private Class2 class2; //getter & setters for class2 } Class2: public class Class2{ Private Class3 class3; //getter & setters for class3 } Class3: public class Class3{ Object[] class4; //getter & setters for class4 } Class4: public class Class4{ private String variable; //getter & setters for variable } I will get only the object of Class1 in dsl level. When I try to remove the variable in Class4, I am facing some problem. I need to iterate the variable in Class4 and check weather all the values in the list of variable are same. workingMemory.assertObject(class1); // in test class I was not suppose to assert the object of Class2 or Class3 or Class4. [when]Some English Text = Class1(cl2 : class2) //in .dsl file [then]Log "{message}"=System.out.println("{message}"); //in .dsl file I tried the above code. But I can remove only the Class2 from Class1. I can’t remove the Class3 from Class2 & Class4 from Class3 for futher iteration. Can some one help me on this issue? Thanks. -- View this message in context: http://www.nabble.com/Removing-Child-Class-Objects-in-dsl-file-level-tf37... Sent from the drools - user mailing list archive at Nabble.com.
