I had a similar issue. What I did was replace "t:updateActionListener property=" with the standardized "f:setPropertyActionListener target=". f:setPropertyActionListener better supports edge cases under Facelets as well.
Other than avoiding the one-time conversion cost of the page templates, there's no benefit to continuing to use t:updateActionListener. I used a regular expression in Eclipse to make the change, so it was pretty painless.
