-----------------------------------------------------------

I have reproduced the issue on Metamer on [this|https://github.com/richfaces/richfaces-qa/tree/RF-12891] branch. The method walk is called multiple times (6 times in this case).

* The [facelet|https://github.com/richfaces/richfaces-qa/blob/3782c40cda365b8c77331bb83680ad1003cba94d/metamer/application/src/main/webapp/components/richDataTable/rf-12891.xhtml] which is reproducing the issue.
* The [bean|https://github.com/richfaces/richfaces-qa/blob/3782c40cda365b8c77331bb83680ad1003cba94d/metamer/application/src/main/java/org/richfaces/tests/metamer/bean/issues/rf12891/RF12891Bean.java].

I have reproduced it on _JBoss AS 7.1.1.Final_. It is _not_ regression IMHO, because I was able to reproduce it with RichFaces from _4.1.Final to 4.3.2.Final_ (I was not able to build Metamer with 4.0.0.Final, but I can try this one if it is needed on some other separated sample).

The description for me is slightly different. Because I was able to reproduce the issue also when the column has just {{<a4j:ajax>}} which does not render an outside element.

Steps to reproduce the issue:
# Build and deploy the Metamer from the above mentioned branch.
# Load this [page|http://localhost:8080/metamer/faces/components/richDataTable/rf-12891.xhtml].
# Click on the picture from the first column.
# See that the server output log has multiple _"Method Walk called"_ entries.

Brian, please let me know If I can do something more for this one.
