Access Application Parameters on SAP Portal page

[Former Member]

Hi all, this is my first blog post.

I would try to explain how to set Application Parameters in a web dynpro page and access them in the java code of the application.

I have this scenario: I have two pages that have the same model but two different iView. I want show or not a toolbar depending on the page I am.

After various attempt I found the solution!

Go to the page on the SAP Portal Content:

Open the page, select the Web Dynpro and select Open:

Here go to All properties > Web Dynpro and select Modify Properties:

In Application Parameters insert <name_of_the_parameter>=<value_for_the_webdynpro>

Save the properties.

Now you have to repeat these steps for the second page (in my case the pages are Users and Users' application, where in one case obn=true and in the other case obn=false).

Now I put in the wdDoInit method of the component controller this code:

IWDProtocolAdapter protAd = WDProtocolAdapter.getProtocolAdapter();

String idreq = protAd.getRequestObject().getParameter("obn");

        if (idreq.equals("true"))

            wdContext.currentUtilsElement().setButtonActionVisibility(WDVisibility.VISIBLE);

        else if (idreq.equals("false"))

            wdContext.currentUtilsElement().setButtonActionVisibility(WDVisibility.NONE);

The code sets to visible or not a button in case of which page is open.
