selected list duplicating in List to list view.



List to List issue: the values in selected list are being duplicated.

Error Messages

No explit error message. The values in Selected list are being duplicated in the list-to-list.

Steps to Reproduce

1. Select few items from the left list and send it over to the right list.
2. Enter some values in an inputText below and click outside. This does a refresh of the section.
2. Click on the Next button to navigate to the next page.
3. The list values selected are duplicated on the right side selection area.

Root Cause

The ListToList values get submitted to the clipboard without the client-side in sync. Thus a subsequent submit does a duplication of the values.


User can change the design to ensure that the ListToList component is in a separate section and the inputText in a different section. This ensures that the values are submitted only on click of Next Button.
