Download to Excel

28 Views

I have a BSP application which is MVC based. When a user clicks on the button of a controller I set cookie on the server side and call a page of flow logic to get the cookie. As the model variables are no more accessible I have to set and get the cookie.

Problem.

After getting the cookie I call several methods to download the data to Excel. The data is extracted correctly but the window of the page of flow logic doesn’t close.

Here is the code on the page of flow logic.

<u><i><b>PROBLEM 1</b></i></u>

<b>LAYOUT</b>

<%@page language="abap" %>

<%@extension name="htmlb" prefix="htmlb" %>

<htmlb:content design="DESIGN2003" >

<htmlb:document disableBackspaceNavigation="TRUE" >

<htmlb:documentHead title="BPR Main Application" >

</htmlb:documentHead>

<htmlb:documentBody>

<htmlb:form>

<script language="JavaScript" type="text/javascript">

window.opener = parent;

window.opener.close();

</script>

</htmlb:form>

</htmlb:documentBody>

</htmlb:document>

</htmlb:content>

<b>

response->set_header_field( name = 'Content-Disposition' value = filename ).

l_len = STRLEN( l_string ).

response->set_cdata( data = l_string length = l_len ).

navigation->response_complete( ).

When I comment this piece of code the window closes

response->set_header_field( name = 'Content-Disposition' value = filename ).

<u><i><b>

PROBLEM 2</b></i></u>

When I place the code of the OnInitialisation in DO_HANDLE_EVENT and don’t set any cookie the downloads takes place successfully but the the pop window for the protect double submit doesn’t go away.

<b><u><i>Where am, I wrong ???</i></u></b>
