Hello, Let's say we have a simple BeanA with one property that is part of equal/hashCode method e.g.: ---------------------------------------- public class BeanA { int someProperty; public int getSomeProperty() { return someProperty; } public void setSomeProperty(int someProperty) { this.someProperty = someProperty; } @Override public boolean equals(final Object other) { if (this == other) return true; if (!(other instanceof BeanA)) return false; BeanA castOther = (BeanA) other; return new EqualsBuilder().append(someProperty, castOther.someProperty).isEquals(); } @Override public int hashCode() { return new HashCodeBuilder(228431015, 1383549405).append( someProperty).toHashCode(); } } ------------------------------------ This bean is inserted into the working memory. Is it something wrong with doing?: wm.modifyRetract(beanA); beanA.setSomeProperty(22); //this is changing the object equality key wm.modifyInsert(beanAHandle, beanA); I know that simple update is not allowed: beanA.SetSomeProperty(22); update(beanAHandle, beanA); //this is wrong I guess there is no difference if this code is outside the rule engine or inside (e.g. in a rule consequence). Thank you, Best Regards, Michal _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
