Hi everybody,
I'd like to use a dropdown menu in my jsp page, therefor I added
<h:selectOneMenu id="selectModifier" value="#{bean.currentItem}">
<f:selectItems value="#{bean.itemList}" />
</h:selectOneMenu>
to my page. The bean provides getter and setters for both properties, whereby
currentItem is of type SelectItem and itemList is an ArrayList containing
SelectItems.
Just a static example copied from jsftags-guide into my bean class:
private SelectItem currentItem;
private ArrayList itemList;
public SelectItem getCurrentItem() {
return new SelectItem("4runner","Toyota 4Runner","Toyota 4Runner - suv");
}
public void setCurrentItem(SelectItem currentItem) {
this.currentItem = currentItem;
}
public ArrayList getItemList() {
this.itemList=new ArrayList();
this.itemList.add(new SelectItem("accord","Honda Accord","Honda Accord -
sedan"));
this.itemList.add(new SelectItem("4runner","Toyota 4Runner","Toyota 4Runner -
suv"));
this.itemList.add(new SelectItem("nissan-z","Nissan Z350","Nissan Z350 -
sports"));
return itemList;
}
public void setItemList(ArrayList itemList) {
this.itemList = itemList;
}
But whenever I try to render the page, I'll get an
'java.lang.IllegalArgumentException: Value is no String and component
treetestformdb:selectModifier does not have a Converter' Exception.
IMHO the returned SelectItem should be rendered as a String automatically
without the need to attach a custom converter.
What am I'm missing here? I'm banging my head for an hour now,
Kurt
