f:setPropertyActionListener, t:updateActionListener and nested dataTables

[Leonardo Calugi]

Hi everyone,
I created a jsf page with a dataTable (b) nested in another dataTable (a). Inside the dataTable b 
there is a commandLink with a <f:setPropertyActionListener>, but when I click on, the 
<f:setPropertyActionListener> doesn't save the right value. The same thing with 
<t:updateActionListener>.
With one dataTable it runs correctly.
I use myfaces 1.2.4 and tomahawk 1.1.7
Any suggest? Thanks
Leonardo
