If a dictionary is invalid, you can save the dictionary. However, you can only generate RL Language for a dictionary that is valid and does not display warnings in the Rules
Designer validation log.
In the validation log, each validation message includes the following:
■
Message: The message provides details on the Oracle Business Rules exception that describes the problem.
■
Dictionary Object: This field displays a path that indicates details that should allow you to identify a component in the dictionary.
■
Property: provides information on a property of the object associated with the warning message.
When you are viewing the validation log, if you select an item and then right-click and select from the list Select and Highlight Object in Editor, Rules Designer moves the
cursor to select the dictionary object. Note that for some validation warnings this functionality is not possible.
4.4.1 Understanding Data Model Validation
Rules Designer performs dictionary validation when you make any change to the dictionary. When Rules Designer displays a warning message, the validation log
includes a message that should assist you in locating the dictionary object that caused the validation warning. For example, the following string indicates that the warning
originates from the data model object named RLFact_1. In addition, the problem is in the property named test_int:
CarRentalData ModelRLFact_1test_intExpression
Working with Rulesets and Rules 4-21
Table 4–3 specifies the parts of the dictionary object name specified in a validation
message.

4.4.2 Understanding Rule Validation
When you click the Validate icon Rules Designer displays the validation log. When you first add a rule you see validation warnings similar to those shown in
Figure 4–30 .
Figure 4–30 Rules Validation Messages
The dictionary object name part of a validation message for a rule includes details that help you to identify the ruleset, the rule, and an area in the rule that is associated with
the validation warning. For example, the following dictionary object specification indicates a problem:
OracleRules1Ruleset_2Rules_1Pattern[1]
In validation messages, the dictionary object name for a rule uses indexes that start at 1. Thus, the first pattern is Pattern[1].
In addition to validating rules, you can also test them in Rules Designer as you are designing them. For more information, see
Section 8.1.1, How to Test Rules Using a Test Function in Rules Designer
.
4.4.3 Understanding Decision Table Validation
When you click the Validate icon Rules Designer displays the validation log. When you first add a Decision Table you see validation warnings similar to those shown in
Figure 4–31 .

Name Description

Data Model Data Model component in dictionary.
RLFact_1 Element name in data model
test_int Property name in the specified element.
Expression Expression part of property.

Figure 4–31 Decision Table Validation Messages
The dictionary object name part of a validation message for a Decision Table includes details that help you to identify the area of the Decision Table that is associated with
the validation warning. For example, the following dictionary object specification indicates a problem in the first action row, and the first action cell of the Decision
Table:
OR1Ruleset_1DecisionTable_1Action[1]Action Cell[1]
In validation messages the dictionary object name for a Decision Table object uses indexes that start at 1. For example, to indicate the first condition cell in the first row in
the Conditions area, the message is as follows:
OracleRules1Ruleset_1DecisionTable_2Condition[1]Condition Cell[1]
This specification indicates the condition cell for the rule with the label R1 in the first row of the Conditions area in a Decision Table as shown in
Figure 4–32 .
