How do I get the Next Button to appear on a form?

Question

I have a form built off of a view. I pass a parameter from a report through a link to launch the form with the appropriate values. I would like user to then be able to navigate to the next set of information from the report without having to navigate all the way back to the report. I tried to activate the Next button with the onClick event and doNext function but the button never appears to the user. Thank you for any assistance!

Samuel,
The reason that you don't get the "Next" button is that the query that the form is running on returns only one row. Take a look at EXAMPLE_APP.EXAMPLE_SQL_REPORT and EXAMPLE_APP.EXAMPLE_FORM. You'll find that this form also does not show the "NEXT" button when called from the report. However if you edit the report and change the link parameter from empno to deptno, you'll find that the button comes up in the form.
I guess the best option you have is to create a custom button that simulates the functionality of the NEXT button i.e. have some logic to find out which empno must be the next one and then call the form like this :
l_empno := <whatever logic you have come up with>
l_url:=<portal_schema>.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=<module_id of the form>&p_arg_names=empno&p_arg_values='||l_empno||'&p_arg_names=_empno_cond&p_arg_values='||<portal_schema>wwv_standard_util.url_encode('=');
<portal_schema>.wwa_app_module.set_target(l_url, 'CALL');
Hope that helps,
