此问题已经经过验证，如果是一个CheckBox控件对应的Hook操作了另外一个字段，只有在执行完当前Action的Commit操作后，才会执行该Hook，而不是立即就能够看到效果，
请注意下面引用的红色字体部分。
Problem
This technote provides clarification as to which hook typesare supported by the IBM® Rational® ClearQuest® Web, versions 2003.06.13 andlater.
Cause
The following statement in the
New ClearQuest WebAdministrators Guide (cq_web_admin.pdf, page 43) is incorrect: "Context-menu hooks and field hooks (for example, value change, validationhooks) are not supported in the ClearQuest Web application."
Solution
Field hooks are indeed supported by the ClearQuest Web. A documentation defecthas been created to correct this statement.
The following table shows what hooks are supported with the ClearQuest Web:
| Type of Field Hook | Description |
Value Changed
(SetFieldValue) | Are executed when the value of the given field changes.
SetFieldValue - set the value of a different field or fields when theValue Change hook of the given field is executed.
The fields to be set must be declared as Web Dependent Fields in the Propertiesof the Form Control for the field with the Value Changed hook.
The fields with the following controls are set to theirnew values immediately when Value Changed hook is executed.
- Combo-Box
- Drop-Down Combo-Box
- Drop-Down List Box
- List Box
- Text Box
The fields with the following controls are set to their new values onlyafter Commit when the Value Changed hooks are executed.
Option Button |
| Value Changed (Field Requiredness) | ClearQuest 2003.06.13 (SR3) and ClearQuest 2003.06.14 (SR4)
SetFieldRequirednessForCurrentAction- Sets the Requiredness (such as Mandatory or Optional) of a different field orfields when the Value Changed hook of the given field is executed. The field ismade editable (which all Mandatory fields must be) only after Commitwhen the Value Changed hook is executed.
ClearQuest2003.06.15 release (SR5) added real-time support for the Value Changed hookwhich sets field requiredness (as Mandatory, Read-only, or Optional) when thefield control is a drop-down combo-box or a drop-down list box. |
| Choice List | Sets the choices associated with a given field.
When a field's own choice list is determined by another field, that other fieldmust list the target field as its web dependant field.
The control types for Choice List Hook fields are: Combo-Box, Drop-DownCombo-Box and Drop-Down List Box. |
| Default Value | Are executed when the when a record is created. |
| Permission | Is fired only when performing an action, not executedwhen the field value changes. |
