Strange issue on MDS and Taskflow

RichardvanMaarenSep 26 2019 — edited Oct 3 2019

All,

Strange situation here, using JDeveloper 12.2.1.3.0

Application has multiple pages and taskflows.

When activating MDS I have the following situation, after logging in, pagen opens with taskflow. However an error message as below is thrown.

When navigating to a different page and taskflow everything is working normally.

Strange thing now is when navigating back to the initial page, taskflow is opened normally.

Strange this is when deactivating MDS, we do not see this issue.....

Configuration based on :http://blog.whitehorses.nl/2018/07/10/the-struggles-of-personalization-in-adf/

Error message which is thrown, a very general message.

Any thoughts on this one ?
