Hello Simon,
Your approach is to give the Element in the backing bean the value, like this:
The bean has the List with the Wrapped Items and one of the items you want to
set with the List in it:
private List<SelectItem> indexTypesForSuche;
private GeVoSuchtyp selectedIndexType;
public List<SelectItem> getIndexTypesForSuche() {
return indexTypesForSuche;
}
public GeVoSuchtyp getSelectedIndexType() {
return selectedIndexType;
}
public void setSelectedIndexType(GeVoSuchtyp pSelectedIndexType) {
selectedIndexType = pSelectedIndexType;
}
Then, I would preselect the Object with a value from the List in the
constructor:
public DokumentSuchenBean() {
indexTypesForSuche = new ArrayList<SelectItem>();
for (Iterator<GeVoSuchtyp> iterator =
jFlowBean.getCodePool().getGeVoSuchtypListe().iterator();
iterator.hasNext();) {
GeVoSuchtyp lSuchtyp = iterator.next();
indexTypesForSuche.add(new SelectItem(lSuchtyp, lSuchtyp
.toString(), lSuchtyp.toString(), false));
}
if(setSelectedIndexType.size>0) {
setSelectedIndexType(indexTypesForSuche.get(0).getValue())
}
}
The jspx would look like this:
<tr:selectOneChoice value="#{DokumentSuchenBean.selectedIndexType}" >
<f:selectItems value="#{DokumentSuchenBean.indexTypesForSuche}"/>
</tr:selectOneChoice>

> Hi,

> So far it's working fine, the only thing bothering me in comparison to the
> selectOneMenu is, that the default selection is an empty element but I'd
> like to have the first element of the bound list of SelectItems to be
> preselected.

> I tried it via setting the value of the selectOneChoice to the first

> So is it even possible to make a preselection? And if so, how to achieve
