State Managed By
Sets the value of the <$cmpStatemanagedBy> constant, which specifies the mechanism used to save state information for the component.
Value |
Description |
---|---|
|
State management is not required, or will be implemented using a mechanism other than cookies or a state management component. For more information, see State Management Mechanisms. |
|
Use cookies to store state. Cookies are sent to the client browser. By reading the cookies, you can get the actual state information that was sent to the client browser by a previous request. |
|
Use a separate component to manage state. Parameters are passed to a component operation that is responsible for maintaining state. For server pages, this is Uniface’s state manager component (USYSSTAT). |
Description
The <$cmpStatemanagedBy> constant is used in the predefined code of preActivate and postActivate triggers of dynamic and static server pages.
Predefined Code in Server Pages
If State Managed By
is set to 1 (Cookie)
, the pre-defined code in the
preActivate and postActivate triggers results in the following runtime code:
preActivate |
---|
trigger preActivate variables string WebServerContext, Cookie, Session, UserContext endvariables getitem/id Cookie, $webinfo("COOKIESIN"), "MY_VARLIST_COOKIE" getlistitems/id /component Cookie end; preActivate |
postActivate |
---|
trigger postActivate variables string WebServerCntxt, SessionId, Varlist endvariables Varlist = $componentinfo($componentname, "VARIABLES") putlistitems/id /component Varlist putitem/id $webinfo("COOKIESOUT"), "MY_VARLIST_COOKIE", Varlist end postActivate |
If State Managed By
is set to 2 (State Management Component)
, the pre-defined code in
the preActivate and postActivate triggers results in the following runtime code:
preActivate |
---|
trigger preActivate variables string WebServerContext, Cookie, Session, UserContext endvariables WebServerContext = $webinfo("WEBSERVERCONTEXT") getitem/id Session, WebServerContext, "SESSION" UserContext = "" activate "USYSSTAT".GetState(Session, $instancename, UserContext) getlistitems/id /component UserContext end; preActivate |
postActivate |
---|
trigger postActivate variables string WebServerCntxt, SessionId, Varlist endvariables WebServerCntxt = $webinfo("WEBSERVERCONTEXT") getitem/id SessionId, WebServerCntxt, "SESSION" Varlist = $componentinfo($componentname, "VARIABLES") putlistitems/id /component Varlist activate "USYSSTAT".SetState(SessionId, $instancename, Varlist) end; postActivate |
