I am using Seam 2.0.2.SP1
and the richfaces version that came bundled with it.
I even tried some other richfaces versions with no success
Are the shown numbers the ids of your entity? the rich face api needs to know what value to
fetchin the combobox. By default it uses the ID, as far as i remember. Hope this helps a bit...
Yes it uses the Id's of the entities when I use it without s:convertEntity when I use s:convertEntity the value of the toString() method is shown.
I'm assuming that the s:selectItems tag is not compatible with the rich:combobox, at least not in the versions I tried.
Does someone have a working example and the version numbers of seam and richfaces would also be interesting.
I also had the same issue with the rich:combobox, which seems to ignore the label attribute within the s:selectItems if the s:convertEntity is present. Regarding the numbers in the combobox, you can modify this behaviour following this example http://in.relation.to/8630.lace or use another rich faces component with a similar behaviour (ie rich:suggestionbox).
Had the same problem and posted it in the richfaces forum.
