Symptoms

Trying to pass a URL Parameter value to a custom task flow added to the Resource Catalog does not work.
Passing the same URL Paramater value to the same task flow works fine from the Navigation model.

Steps to Reproduce
===================
The steps are the same as in the following blog:
http://andrejusb.blogspot.com/2011/05/initializing-adf-task-flow-parameters.html  -  DISCLAIMER: Oracle is not responsible for instructions/information from 3rd party sites.

1. Create an ADF Fusion project with a simple task flow that takes an input parameter (p1) and displays it

2. Deploy the task flow to a JAR file

3. Create a File System IDE connection to the container folder of the JAR file

4. Create a new WebCenter Portal application with all the default settings

5. Open the default-navigation-model.xml

6. Drag and drop the task flow from the IDE connection to the root of the default-navigation-model

7. Add a new URL Paramater with the following details:

Name: p1
Value: Param through Link

8. Execute the page

9. Click on the newly added link in the navigation
and notice that the task flow appears and displays the following parameter value as expected:
Param through Link

So far so good.

10. Open the default-catalog.xml

11. Drag and drop the task flow from the IDE connection

12. Add a new URL Parameter with the similar details as for the navigation link:

Name: p1
Value: Param through RC

13. Execute the page

14. Edit the page with CTRL+Shift+E

15. Click on Add Content to bring up the resource catalog

16. Add the custom task flow

17. Notice that the task flow does not display anything, so the parameters does not get initialized through the resource catalog, which is not expected!
