Problem(Abstract)
This technote explains that value changed hook do not fire on the IBM® Rational® ClearQuest® unless the record is saved.
Resolving the problem
A Value Changed hook will fire on the ClearQuest client, but not on the ClearQuest Web clients. Even if the refresh button is added to the form, the value changed hook still does not fire.
To resolve this issue, replace the Value Changed hook with a Validation hook. The same hook code can be placed in the validation column for the desired field, and will fire on all ClearQuest clients. The validation hook will immediately fire on the ClearQuest Web client, but the form will need to be refreshed. See instructions for creating a refresh button.
Creating the Refresh button
To create the refresh button,
Create a record script hook with no code inside and name it Refresh.
Create a button on the form and label this button as "Refresh".
Go to the properties of the button control (by right clicking on the button > Properties). On the extended tab, under the "click hook" field, select the refresh record script. Also make sure to check the "click hook" field under the "Enable for web" section.
The validation hook will immediately fire on the ClearQuest client. The user will need to click on the newly created refresh button to see the validation hook fire on the web.
