[TRINIDAD] SelectOneChoice preselection possible?
Hi, at first I was using the default JSF 1.2 ComboBox (selectOneMenu) but then switchted to the Trinidad equivalent (selectOneChoice) to get Ajax functionality. 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 element of the list in the constructor of the bean, but that didn't work. So is it even possible to make a preselection? And if so, how to achieve it?

AW: [TRINIDAD] SelectOneChoice preselection possible?
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 ListSelectItem indexTypesForSuche;
private GeVoSuchtyp selectedIndexType;
public ListSelectItem 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 ArrayListSelectItem();
for (IteratorGeVoSuchtyp iterator =
jFlowBean.getCodePool().getGeVoSuchtypListe().iterator();
iterator.hasNext();) {
GeVoSuchtyp lSuchtyp = iterator.next();
indexTypesForSuche.add(new SelectItem(lSuchtyp, lSuchtyp
.toString(), lSuchtyp.toString(), false));
}
if(setSelectedIndexType.size0) {
setSelectedIndexType(indexTypesForSuche.get(0).getValue())
}
}
The jspx would look like this:
tr:selectOneChoice value=#{DokumentSuchenBean.selectedIndexType}
f:selectItems value=#{DokumentSuchenBean.indexTypesForSuche}/
/tr:selectOneChoice
