Changing property values in event definitions
In the event definition editor, all values associated with event definition properties are displayed in the Properties view.
You can use the Properties view to set or change the values of properties.
To change property values in an event definition:
Procedure
- In the event definition, select the property for which you want to set or change values.
- Click the Properties tab to open the Properties view.
- Click the General tab to open the General page. As shown in the figure, the name and XPath of the property are displayed. However, the name and path cannot be changed on this page.
- Click the Details tab to open the Details page.
- If you want the property to be required, select the Required check box. If that if you are overriding a property from a parent event definition and the property has been specified as required in the parent, the Required check box will already be selected and you should not clear the check box.
- If you want to specify a default value for the property, position your cursor in the Default value field and type in a string value. The default value represents the value that should be used during content completion for an event that is missing a required property. If you are overriding a property from a parent event definition and you do not specify a default value, the default value will be inherited from the parent event definition.
- If you want to specify minimum and maximum permitted values for the property, select the radio button to the left of the Minimum value field and then type in string values in the Minimum value and Maximum value fields.
If the event definition allows a range of values for a property, these fields define the lower and upper bounds of that range. If you specify only a minimum value, the permitted range has no upper bound. Similarly, if you specify only a maximum value, the permitted range has no lower bound. These fields are optional and cannot be specified if permitted values are specified. If that if you are overriding a property from a parent event definition, you should consult the inheritance rules at the bottom of this topic before specifying any minimum and maximum values.
- If you want to specify one or more permitted values for the property:
- Select Permitted values.
- Beside the Permitted values list box, click the Add button to add a default value to the Permitted values list box.
- In the Permitted values list box, highlight the default value (as shown in the figure) and then type in the actual string value that you want to use.
- Repeat the previous two steps for each permitted value that you want to add. Permitted values are optional and they cannot be specified if minimum and maximum values are specified. If that if you are overriding a property from a parent event definition, you should consult the inheritance rules at the bottom of this topic before specifying any permitted values.
Example
If you are overriding a property from a parent event definition, the following inheritance rules apply to minimum and maximum values and permitted values:
- If the parent event definition defines minimum and maximum values but the child event definition defines permitted values, the minimum and maximum values defined by the parent are ignored.
- If the parent event definition defines permitted values but the child event definition defines minimum and maximum values, the permitted values defined by the parent are ignored.
- If the parent event definition defines only a maximum value but the child event definition defines only a minimum value, the child inherits the maximum value defined by the parent.
- If the child event definition does not specify either minimum and maximum values or permitted values, the minimum and maximum values or the permitted values specified by the parent are inherited.
