Hi, I get the following error when I try to build and deploy: Unable to build constraint as '_default' is invalid : [Rule name='myRuleName'] It yields this error because of this pattern in my drl file: MyType(_default == DefaultType.YES) In my java class MyType I have something like this: public class MyType { .... @XmlAttribute(name = "default") protected DefaultType _default; .... } where DefaultType is an enum. Here is the hole enum class: @XmlType(name = "defaultType") @XmlEnum public enum DefaultType { @XmlEnumValue("yes") YES("yes"); private final String value; DefaultType(String v) { value = v; } public String value() { return value; } public static DefaultType fromValue(String v) { for (DefaultType c: DefaultType.values()) { if (c.value.equals(v)) { return c; } } throw new IllegalArgumentException(v); } } Can you help me? I don't see where the problem is... Any suggestions are much appreciated. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
