Hi,
I have a Web Dynpro ABAP application running in the portal which display some data in a textedit depending on a couple of parameters. These parameters are captured using a selection screen in a BI iView and sent using a portal event.
Here's the problem : when the user navigates to another page and then back to the page containing the WD ABAP iView, the textedit element already contains some data (corresponding to the previous selection). It should be empty because the BI iView is initialized and no selection has been made.
Is there a way to invalidate the context when the user navigates to another page in the portal? I tried to use the WDDOEXIT method but it doesn't work.
Regards,
Pierre
on back there must be some inbound plug handler, write a code to invalidate the context node inside the handler
use INVALIDATE method of the IF_WD_CONTEXT_NODE.

if the link is in the portal and not inside the WD component object then the WD don't know what is happening because the link is an IVIEW outside your WD code and is opening a regular IVIEW (like a new tab) but the WD is not reading any action so you don't have control of what happens outside the WD component, for the WD is actually a user IDLE in the object.

If you add the IVIEW as a link inside your webdynpro and create an action link (instead of having the link outside the webdynpro) then your problem is solve.
you will have control between the WD an the external IVIEW, it will be required to call the IVIEW form the WD.
I just did that with a standard SAP iview that I have in my portal and it works fine.
thanks!

Hi,
You have to disable to Client Caching property for the WebDynpro Iview.
That will make sure that when the browser back button or a portal link is used to come back to the application. A new instance of the webDynpro application is launched.
Please make sure you are not using any suspend and resume plugs in the Web dynpro component.
Thanks,
Kalyan
