Navigating away from Web Dynpro after warning.

Question

Hi Experts,
I wanted to see if anyone can shed light on something I've been trying to implement. I'm working with NWDS 7.0.18
I developed a collection of WDP Java apps that reside in the same workset.
While working in one of the apps, if the user clicks a link to another app in the detailed navigation area and they haven't saved what they have been doing in the current app, then I want to display a message like: "You haven't saved you worked, are you sure you want to leave?? YES/NO"
If the user clicks yes, how do I navigate them to the app they clicked on? Or the role they clicked on? Or the workset they clicked on? I have put the above message in the wdDoExit() method of the View controller. The method checks for unsaved changes and if so, displays the message.  I have two event handlers YesExit and NoExit. NoExit does nothing, what do I need to put in YesExit??
Any help is greatly appreciated.
Thanks
MM

Hi,
have you tried "work protect mode"? I don't know, if it works, when work protect mode is set in the onExit function, but give it a try.
The first example demonstrates how to define the work-protect mode level:
// Define the needed level. The level can be switched during
// the application lift time, i.e. it can for example be
// switched for different views.
WDPortalWorkProtectMode.setApplicationDirtyControl(
WDApplicationIsDirtyMode.NONE);
WDPortalWorkProtectMode.setApplicationDirtyControl(
WDApplicationIsDirtyMode.APPLICATION_ONLY);
WDPortalWorkProtectMode.setApplicationDirtyControl(
WDApplicationIsDirtyMode.STANDARD);
The second example demonstrates how to define the u201Cdirty stateu201D of an application:
// Set the u201Cdirty stateu201D to YES, i.e. the application is dirty and
// a navigation should be launched in a new window to make sure that
// no data is lost
WDPortalWorkProtectMode.setApplicationDirty(true);
// Set the u201Cdirty stateu201D to FALSE, i.e. the application state is u201Ccleanu201D
// and therefore the navigation is launched inplace and the
// running application is left.
WDPortalWorkProtectMode.setApplicationDirty(true);
Here is the document, i got this code from with some explanations about work protect mode: http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/a891e490-0201-0010-fb99-b7e4f5dda2ec&overridelayout=true
