Selected element in HtmlSelectOneMenu is not correctly set

Question

Hi,
I have multiple dropdown lists in a jsf page. It seems that there is a problem with the generated html regarding the "selected" attribute of
the "option" html tag. It does not corresponds to the value of the
h:selectOneMenu id ="tests" value="#{test.test}" ....
Actually there is no selected attribute in the generated HTML.
In general the question is how to force an element from h:selectOneMenu to be selected.

Answer 1

here I have three dropdown lists with the following semantic
the first list specifies a season, the second specifies a country according the season in the first list and the third lists specifies the resorts according the country and the season
the problem is the if you switch twice the seasons the winter-> summer->winter the resorts and the country list are out of sink. despite the fact that the bean properties in the managed bean are synced.
THIS IS THE MANAGED BEAN
