the class AbstractCompare method getTriggerValue.

/**
 * Get the value for the trigger.
 * <p>
 * If no request is passed in, the current value of the trigger is used.
 * </p>
 * <p>
 * It will return the same "value" the client would have used in its subordinate logic.
 * </p>
 * <p>
 * The trigger value will either be (i) a date formatted String for WDateFields, (ii) a BigDecimal for WNumberFields
 * or (iii) a List of String values for MultiSelect components or (iv) a String value.
 * </p>
 *
 * @param request the request being processed, can be null
 * @return the value to be used for the trigger
