Hello Jon,
It seems like I owe you an apology. I didn’t pay too much attention to the logic you are trying to implement, plus I thought you’ll also consider Rutger post. To be honest, I never tried to use x01-x10 outside an on-demand process, until your thread.
So let’s start from the beginning. Although we are using the term global variables with regards to the x01-x10 variables (and they are indeed defined as global variables in the wwv_flow package) they don’t have the same functionality as application items, and in our context, mainly persistence. In fact, they were created to save us the need to define application items as temporary items, to be used only to pass values in AJAX processes.
If you set one of these variables, using the addParam() method, its value will be available to you in the on-demand process that you reference in your AJAX request, but the value will not be set in session-state (like application/page items) and will not be persistence.
If you want to use this value outside the on-demand process, you need to assign it to a page or application item. In your case the code
:P1_MY_PAGE_VALUE := apex_application.g_x01;should be part of the on-demand ‘jmf_test' process. The P1_MY_PAGE_VALUE should be set with a Source Used of “Only …” so it will be populated from session state.
The code of
var ajaxRequest = new htmldb_Get(null, $v('pFlowId'),null, 0);should only be used when you need to save session state of application/page items from JavaScript (and not with the x01-x10 variables).
Hope this time things are clearer and you’ll be able to achieve what you need. If, for any reason, they are not, please post again.

Arie.
