Brian Leathem commented on RF-12592:
------------------------------------
An alternative workaround is to not embed the _contextMenu_ directly in the
table column, but rather to create a top-level _contextMenu_ component and
attach it to the extendedData table, as in:
{code}
<rich:contextMenu target="table" mode="ajax">
<rich:menuItem label="View" render="popupContent"
oncomplete="#{rich:component('popup')}.show();" mode="ajax"
icon="/images/icons/open.gif"/>
</rich:contextMenu>
{code}
This is as demonstrated in the richfaces showcase. The bonus of this, is you
create only a single component element, instead of one component for each table
row. This results in a smaller component tree, and better performance. The
downside is that you cannot tailor the _contextMenu_ to the data in each row
until macro-substitution (RF-11842) is supported by the RF 4 _contextMenu_.
> rich:contextMenu clipped by rich:extendedDataTable cells.

> The context menu gets clipped by extendedDataTable cells. The same code works
> fine with RF3 (see the attached screenshots and test page). The context menu
> is correctly displayed if extendedDataTable is replaced with dataTable
> (attached dataTable.png).
