After some work, I found a solution to the problem. It isn't from the selectItem tag. It is a problem of using ajax4jsf with jsf and seam together.

To make it work you must use the region and page ajax4jsf's tags. 

The tag page must go after the jsf view tag. This is due a problem of ajax4jsf and myfaces. More explanation of this is found in the ajax4jsf page. 

Then put the combo between the region tag. If you want to refresh something outside of the region, you have to set the option renderRegionOnly to false

Here is the code that worked for me.
