Thomas, in your case
getAsString returns string representation of object and the representation can be checked in HTML source - see "value" attributes of HTML select element getAsObject method gets String value from the "value" attribute of HTML element so in order to see "label" as parameter to getAsObject, you need to do: Map<String, String> sortedCountryList = new TreeMap<String,String>(); sortedCountryList.put(label, label); In order to work with select elements, I would recommend to use javax.faces.model.SelectItem class instead. 2009/10/8 Thomas Hamacher <[email protected]> > Hi @all, > > I´m struggling around with the converters and maybe someone can give me, > what I´m doing wrong. > > I use the following code in my web-page: > > <tr:selectOneChoice id="country" > value="#{signUpForm.country}" > simple="true" > required="true" > converter="#{commonDataHelper.countryConverter}" > unselectedLabel="#{messages['label.address.country.unselected']}"> > <f:selectItems value="#{commonDataHelper.countrySelectionList}" /> > </tr:selectOneChoice> > > The selectItems are filled by the following method: > > public Map<String, Country> getCountrySelectionList() { > > Map<String, Country> sortedCountryList = new TreeMap<String, > Country>(); > > for (Country country : getCountryManager().getAllCountries()) { > String label = CountryConverter.getMessage(country); > sortedCountryList.put(label, country); > } > > return sortedCountryList; > } > > Now as soon as my converter´s getAsObject()-method is called, I get the > toString() representation of my country´s object as the String-parameter. > But this is not what I need, as this is of no value to me.
