Unable to Pass Parameters Between Data Visualization Taskflows When Added to Other Taskflows (Doc ID 2267618.1)

Last updated on MAY 18, 2017

Applies to:

Oracle WebCenter Portal - Version 12.2.1.0.0 and later
Information in this document applies to any platform.

Symptoms

Using WebCenter Portal 12.2.1.x.
Attempting to pass parameters between two taskflows on a portal page and it is not working all of the time. It seems to work every other time.

These taskflows were created using WebCenter Portal and they contain Data Presentation Visualization taskflows on them.
The Parameter passing is from taskflow one to taskflow two, in that any row selected in the first taskflow will automatically refresh the second taskflow using the event DPRowSelection.
This is setup for ANY COMPONENT on the page that sets the value to refresh the parameter.

If the page with just the Data Presentation Visualizations Taskflows, for the same content, the parameter passing will work all of the time. The difference in that case is you can specify the exact source that is setting the parameter value instead of using ANY COMPONENT.
