Portal Navigation in WebDynpro

[Former Member]

Hi,

I use the method WDPortalNavigation.navigateAbsolute() to navigate between two different web dynpro apps on the portal and also pass data between them. The last parameter of the method contains the data to be passed(in name value pairs).

Though the navigation works, am not able to retrieve any data(that is passed from the source application) from the parameters in the request object of the target application... using WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<parameter name>");

What could be the reason for this?

Thanks

I found that in some cases, if the params have the prefix "app.", the WDWebContextAdapter is able to retrieve this information, but if "app." is missing, the value will resolve to null.

so a param will be "?app.value=85"

retrive getRequestParameter("app.value")

<u>Solution 1 (For default Configuration of the Iview - Isolation method = URL)</u>

1. Do the Web Dynpro Programming as required for the Portal Navigation using WDPortalNavigation Class

2. Create IViews in Portal for the applications

3. ****** In the Iview Property list, maintain the value of "com.sap.portal.reserved.iview.ParamList" as "" for the Receiver application.****

<u>Solution 2</u>

1. Change the "Isolation Method" property of the Receiver Iview to "EMBEDDED" OR "PUMPED"

Hi Shakeel,

If the work around Sam suggests works, that's great. SAP for its part has acknowledged the problem and has inserted a fix starting in Service Stack 4.

Hope this helps,
