    JSON object request response using AJAX Link to this post

    I managed to connect to a JSON server using ajax and the sapphire Restful server api, but I am not able to display the dynamic data using a template file as my module code is not able to find the template file.Upon a ?debug_request=1. the code stops execution here
    Latest request params: array (
    'Action' => 'display',
    'ID' => '8298574',
    'OtherID' => NULL,
    )

    and if I use the $this->renderWith('displaypage'); or return $this->renderWith(array('displaypage','Page')); on my dataobject it goes for an infinite loop.

    template code in file is
    <% if display %>
    <h3>$objectType<h3>
    <% end_if %>

    Is there anyway that my controller can default to handle request as the above and display the template both on AJAX and without.....?

    Any thoughts will be helpful

    Cheers.

    Re: JSON object request response using AJAX Link to this post

    I do see an infinite loop coming up - if I get you right, that is. Looks like your url is something like

    /yourpage/display/8298574/

    This means action 'display' will trigger the display() method on your page. This method then starts to render you page using your template. In your template, the <% if display %> again triggers your display() method that then starts to render your page using the template, and... Loop accomplished!

    So if this is the situation, you could try and remove <% if display %> If something really does need checking, you could create some CheckFirst() method in your page controller and use <% if CheckFirst %>

    Hope this makes some sense

    Hi Martimiz,

    Thanks for the great help....It could be an infinite loop but I dont know which template is being assigned to my controller basically...
    basically my url is something like this:

    displaymanager/display/display/8298575

    where displaymanager is my module I am developing... and the page I am using is
    display and the action is also display and the ID is 8298575 via an ajax call
    'Action' => 'display',
    'ID' => '8298575',
    'OtherID' => NULL,

    Is this because I cannot use a page name as display and the method as the same "display"
