Mike Kienenberger commented on MYFACES-2916:
--------------------------------------------
Note that there a number of different ways to deal with this problem.
The easiest is to change your backing bean.
Other solutions are:
1) wrap your literal value in some kind of conversion function (ie, a facelets
function that converts a Number to an Integer)
2) Possibly you can manually specify a converter for the value to force it to
be read/written as an integer -- not as sure about this one.
I'm pretty sure there are a number of other workarounds as well which have been
documented in the past -- search the mailing list archives and the wiki to find
them.
