Hi
I remember an issue not the same but related:
http://issues.apache.org/jira/browse/MYFACES-1819
In few words the problem is that in EL, expressions like
"#{bean.map['somekey']}" returns null when getType() is called. Note this
does not happens in jsf 1.1, but on jsf 1.2.
Checking the code of f:setPropertyActionListener, it just do a simple call
like this:
target.setValue(ectx, value.getValue(ectx));
But t:updateActionListener has an additional converter property, so it try
to use the converter before call setValue.
It is a bug on t:updateActionListener, so it could be good create an issue
on
http://issues.apache.org/jira/browse/TOMAHAWK
to solve it in a similar way as MYFACES-1819 does.

Leonardo Uribe
