             Summary: extendedatatable: Scrolling position is lost after submit
                 Key: RF-13435
                 URL: https://issues.jboss.org/browse/RF-13435
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 4.3.4
         Environment: ALL
            Reporter: Holger Walter


Issue is similar to RF-5312.

In EDT, the current scrolling position is lost (reset to 0) after a submit.

Steps to reproduce:
1. Use the showcase for the EDT(version 4.3.4)
2. Adapt the xhtml file by adding a simple submit button ( <h:commandButton value="Submit" />)
3. Activate the 'ajax loading' checkbox
4. Scroll down in the table
5. Press the new submit button
6. The scrolling position is lost

This might sound as a minor problem, but in case of using the EDT with ajax data loading, a user can scroll quite far until he may find the row on which he wants to do some actions. If the scrolling position is reset to 0 after each submit, it gets quite tedious for a user scrolling every time to this old position in the table.

I've seen that the current position is already stored in componentState, but unfortunately it is getting reset on submit.

I already tried a workaround, by using the 'onready' event of the EDT after a submit to trigger scrolling to the desired position with javascript but this does not work  reliably on one hand, and triggers an additional ajax call which may cause that messages in h:messages are lost.
