Passing multiple values from a page to another in Oracle APEX
<p>I wish to know the way to pass multiple values from a page to another and being stored in session. </p>

<p>The current generated URL is: </p>

<pre><code>https://server_name/apex/f?p=285:20:SESSION_ID::NO:20:P21_ACTIVITY_NAME:1:P20_USER_NAME:APEX_USER
</code></pre>

<p>Actually I wanted to pass <code>P21_ACTIVITY_NAME</code> and <code>P20_USER_NAME</code> to another page, but with the URL mentioned above, the value of <code>P21_ACTIVITY_NAME</code> in session is  1:P20_USER_NAME and value of <code>P20_USER_NAME</code> is <code>null</code></p>
