Issue with apex_util.prepare_url not including host in certain Task Events (Approval/Reject) – APEX 24.2.1

De EncryptMay 30 2025 — edited May 30 2025

I'm currently using Oracle APEX version 24.2.1 and working with APEX Tasks to send notifications that include a link to the task detail page.

Every task is created from a workflow.

(Approval/Reject)
l_url := apex_util.host_url || apex_util.prepare_url(
p_url => 'f?p=1000:1::::1:'
, p_checksum_type => 'PUBLIC_BOOKMARK'
, p_plain_url => true
);

(Create)
l_url := apex_util.prepare_url(
p_url => 'f?p=1000:1::::1:'
, p_checksum_type => 'PUBLIC_BOOKMARK'
, p_plain_url => true
);

Here’s the issue I encountered:

  • When I use apex_util.prepare_url alone in the "Create" event, the returned URL includes the full host, for example:
    https://example.com/ords/r/f?p=123:456:::NO::P456_ID:100

  • But when I use the same **apex_util.prepare_url** alone in the "Approval" or "Reject" events, the returned URL does not include the host, and I only get the relative path, like:
    /ords/r/f?p=123:456:::NO::P456_ID:100

  • If I try to use apex_util.host_url || apex_util.prepare_url(...) in the “Create” the result URL includes a duplicate protocol, like:
    http://https://example.com/ords/r/f?p=1000:1::::1:

As a result, I have to handle them differently:

  • For "Create" event → apex_util.prepare_url alone is fine
  • For "Approval"/"Reject" events → I have to use apex_util.host_url || apex_util.prepare_url(...) to get the full URL with host

My questions are:

  1. Why does the behavior of apex_util.prepare_url differ between the "Create" event and the "Approval"/"Reject" events?
  2. Is there a recommended or consistent approach to ensure the full URL (with host) is always returned regardless of the event?

Thank you for your help!
