Refreshing page item after session state changed

Noone? Shouldn't this be something easy? It can't be true that all I can do here is to reload the whole page or hardcode every single item with 'set value' DAs.

@Neil Clare

Thank you very much for your suggestion. It works, but unfortunately also only by hardcoding every page item in the 'Items to return' field. Still a good way for static pages I did not know about.

I solved the problem 'outside' of apex using javascript+jquery.

In case any other poor soul faces a similar problem, here is what I did:

1. I created a procedure which produces the dynamic content for a page and returns it in a json string. The top level keys of the json string match the page item names (excluding the PXX_ prefix) and the values are of course the values for the items.

Very simplified - something like: 

v_result_as_json := '{"given_name":"some name", "job_title":"some job title"}'; --would fill the page items P2_GIVEN_NAME and P2_JOB_TITLE

HTP.p (v_result_as_json);

2. In APEX I created an application process which called this procedure. In my case I called it 'load_blueprint' and it fetches two parameters.

It looks something like:

declare

v_blueprint_ids VARCHAR2(4000);

v_consider VARCHAR2(4000);

begin

v_blueprint_ids := APEX_APPLICATION.g_x01;

v_consider := APEX_APPLICATION.g_x02;

gui_creation.create_account_creation_gui(v_blueprint_ids,v_consider);

end;

3. On the 'load' button which shall refresh the parts of the page I need to be refreshed, I added a dynamic action which executes javascript. This script calls the application process with the needed parameters and handles the refreshing of the page items in the provided callback function

apex.server.process ("load_blueprint", {x01 : $v(pagePrefix + "BLUEPRINTS"), x02: $v(pagePrefix + "CONSIDER")},{

dataType: "JSON", success: function(pData){

     var jsonObject = pData;

    //iterate over the keys

    var keys = Object.keys(jsonObject);

    for(var i=0;i<keys.length;i++){

        var key = keys[i];

        var value = jsonObject[key];

        var domElementSelector = '#' + pagePrefix + key.toUpperCase();

        $(domElementSelector).each(

        function () {

            var foundID = $(this).attr('id');

            $s(foundID, value);

            $(this).trigger('change');

     }

          ) 

    }

}});

Does not feel like the most elegant solution, but it works.

I wish APEX would provide something out of the box. Refreshing parts of a page should be a very common requirement. So it should be something easy like a dynamic action with a 'synchronize DOM with session state' option or something similar.
