helpString Allows to assign a help id for the element. If set, a help symbol will be displayed beside the element, which will generate an onHelp event if the icon is clicked. The id can be used to display a special page of the help system. The help system is not part of the Common-Controls Framework.

To generate the hyperlink some default framework resources where used:
Resource KeyDescriptionDefault optional onclick script handler. The handler can include a {0} placeholder for the help id- the target where to open the hyperlink_blank tooltip for the hyperlinkcontext help

Authorizations are checked using the object in the user session. The principal object is registered in the session with the method, Principal). It is made available by the application developer by implementing the principal interface. In this manner, any authorization system can be very easily connected within the framework.

Authorizations are always specified in the form of an Access Control List (ACL). What is involved here is a semicolon-delimited list with individual authorizations. The framweork supports the following authorization types, which, however, can be expanded at will by the application developer:

true|false ->
#rolename ->
$functionname ->
