I have an Initiator task, assosiated to a Human Task which points to an external UI (deployed on a tomcat).
Mostly, it works as expected (the link appears on the workspace, under "Applications", I can click it and it instantiates correctly, and this task on the workspace redirects to the webpage I deployed on the tomcat.
The unexpected behaviour occurs in between, when I Click on the Application Link, and it shows a popup redirecting to a "404 - Not found"
The URL of the 404 page is the following:
And the error trace:
<_logUnhandledException>
oracle.adf.controller.ControllerException: ADFC-06018: Task flow ID EL expression '#{pageFlowScope.taskDetailsView.remoteTaskDefId}' on activity '/WEB-INF/taskDetail-task-flow-definition.xml#taskDetail-task-flow-definition@remoteTaskFlowCall' evaluated to null.
