About Threadbar Behavior

If the user clicks the thread button, then SWE creates a new bookmark, and then displays a bookmarked view. The bookmark ID for the new view is the current SWE count plus 1. Siebel CRM sends this count to the Siebel Server in the request. The threadbar does the following:

• If Siebel CRM requests a new screen, then SWE creates a new thread that replaces the current thread.
• If a user clicks a view button, then SWE replaces the last thread step with the view that the user requests.
• If the user clicks a link, then SWE appends a new step to the threadbar for the view that the tag references.
• If the user clicks a thread button, then SWE deletes all the thread buttons that exist to the right of the button that the user clicks. It deletes the thread up to the step view according to the value of the SWEBMCount parameter.
• If a thread applet or thread field is not defined for a view, and if Siebel CRM displays this view, then SWE does not update the thread button.

The bookmark ID assignment policy does not modify the bookmark deletion policy. Siebel CRM keeps the 20 bookmarks that it created most recently and deletes previous bookmarks, by default. If the SWE count in the user request is less than the SWE count on the Siebel Server, then Siebel CRM deletes all the bookmarks that contain a SWE count that is larger than the count in the user request.

Usage for the threadbar tags is similar to behavior of the following tags:

• Screenbar Tag
• View Bar Tag
