Refresh problem of Webdynpro application which is wrapped in a BSP IFrame

Question

I have a BSP Iframe inside which I am calling a webdynpro application ('zwdc_re_replenishment'). The requirement is that this WD application should be reloaded whenever a timeout occurs. Currently, when there is a timeout, an error is shown.
In order to achieve this, for this WD Application , I have a SICF node to which I have attached a customized Errorpage via the option 'Redirect URL'.
Whenever the WD application undergoes a timeout error, my custom error page is called which is named as errorpage.htm. On this page in the 'OnInitialization event', I try to call the WD application URL again (via the following code) which should reload the application. But instead I get a blank page.
CALL METHOD cl_wd_utilities=>construct_wd_url
  EXPORTING
    application_name = 'zwdc_re_replenishment'
  IMPORTING
    out_absolute_url = lv_def_url.
response->redirect( url         = lv_def_url
                    permanently = 1 ).
Just as a note I have already tried out the following methods as well but nothing works
*navigation->exit( lv_def_url ).
*navigation->call_application( lv_def_url ).
Is this because my WD application is inside a BSP Iframe and therefore reloading it manually does not work ?
Please help!
Thanks.

Hi Thomas,
First of all, thanks a lot for replying !!
Sorry for the confusion. Although seems like you have answered my question already.
Actually the requirement for embedding WDA inside a BSP Iframe came up since there are some WD report applications  that are accessed by very controlled environments in which the users were not able to close the WDA session directly (without the IFrame)  and were getting some errors. Hence the WDAs had to be wrapped inside BSP IFrame which solved the above problem.
I am working with only one BSP app which has the Iframe and one WD app which is called within the BSP app.
Now, the other requirement that came up was that whenever the WDA session inside the BSP IFrame expires, there should be no error page and instead the WD app should be reloaded.
So  I was trying to reload the WD App in the following way.
1. For the SICF node of WDA, I attached an errorpage.htm for all the tabs under the tab 'Error Pages'. I have defined this errorpage.htm inside the same BSP App which has got another default.htm page. So the BSP App has 2 views : default.htm which has the IFrame and Errorpage.htm.
2. So now when the WDA expires, the events of errorpage.htm are called like OnInitialization, In this event I was calling the methods navigation->exit( 'URL of the same WDA' ).
I did this because I wanted to reload the WDA whenever it expires. I tried to specify the WDA Url in the SICF node of the same WDA in 'Redirect URL' under the Error Page tabs but it didnot work.
Now I realize this is not gonna work. I didnot want to modify the WDA and so I didnot specify any exit plugs in the WDA which would have taken care of reloading the WDA. But that seems to be the only way out.
Actually speaking there are multiple WDAs which will open inside the same BSP IFrame via their own Application URLs. I have coded the BSP IFrame to read the URL Parameters and open up the corresponding WDA.  So now I have to define an exit plug in all of these WDAs.
Do you suggest that this will solve the problem of WDA refresh ? Just to confirm.
Thanks again.
