Setting iView Parameters

Question

Hello,
I have an issue with setting iView Parameters. I do the following:
response.write("Converting...<br/>");
                              iiv.putAttribute("ApplicationParameter","queryid="+request.getParameter("queryid"));
                              try
                                   iiv.save();
                                   iiv.notifyAll();
                              }catch (ValidationException ve)
                                   response.write(ve.toString());
                              catch (IOException ie)
                                   response.write(ie.toString());
However, when I see the iView properties in the portal the value is not changed. When reading the value programatically, it is changed. Are there two of them or do I have a caching issue here?
I already tried clearing browser cache and so forth, but problem remains.
My code is supposed to change iView-ApplicationParameters..

Hi,
I found all information I needed in help.sap.com.
So I wrote a little portal component to update a custom iview parameter and it is working fine for me.
Here's my code:
Sharing References:
<property name="SharingReference" value="com.sap.portal.ivs.api_iview,com.sap.portal.pcd.glservice,com.sap.portal.pcm.admin.apiservice"/>
Custom Parameter in portalapp.xml
<component-profile>
<property name="AuthScheme" value="anonymous"/>
<property name="MTAGCustom" value="Test"/>
</component-profile>
and my Java Code to update(change the value:
Imports:
import java.io.IOException;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.inqmy.lib.xml.parser.dtd.ValidationException;
import com.sap.portal.directory.Constants;
import com.sap.portal.pcm.admin.PcmConstants;
import com.sap.portal.pcm.iview.IiView;
import com.sapportals.portal.pcd.gl.IPcdContext;
Code Snippet:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(Context.SECURITY_PRINCIPAL, request.getUser());
env.put(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);
InitialContext iCtx = null;
try
  String iViewID = "pcd:portal_content/com.mtag.test/com.mtag.testcomponent";
  iCtx = new InitialContext(env);
  IiView myIView =(IiView)iCtx.lookup(iViewID);
  myIView.putAttribute("MTAGCustom","newValue");
  myIView.save();
  myIView.notifyAll();
} catch(Exception Ex) {
  Ex.printStackTrace();
I deployed the component and create an IView from PAR. I started the iView in Preview Mode and the Custom Parameter "MTAGCustom" now has the new Value "newValue"
Let me know if it helps (Reward Points are appreciated if helpful
