Joe Rossi commented on MYFACES-3370:
------------------------------------
Culprit appears to be
org.apache.myfaces.shared.util.SelectItemsIterator.hasNext():
if (child instanceof UISelectItem)
{
UISelectItem uiSelectItem = (UISelectItem) child;
Object item = uiSelectItem.getValue();
if (item == null)
{
// no value attribute --> create the SelectItem out of the
other attributes
Object itemValue = uiSelectItem.getItemValue();
String label = uiSelectItem.getItemLabel();
String description = uiSelectItem.getItemDescription();
boolean disabled = uiSelectItem.isItemDisabled();
boolean escape = uiSelectItem.isItemEscaped();
boolean noSelectionOption =
uiSelectItem.isNoSelectionOption();
if (label == null)
{
label = itemValue.toString();
}
item = new SelectItem(itemValue, label, description,
disabled, escape, noSelectionOption);
}
else if (!(item instanceof SelectItem))
{
ValueExpression expression =
uiSelectItem.getValueExpression("value");
throw new IllegalArgumentException("ValueExpression '"
+ (expression == null ? null :
expression.getExpressionString()) + "' of UISelectItem : "
+ RendererUtils.getPathToComponent(child) + " does
not reference an Object of type SelectItem");
}
_nextItem = (SelectItem) item;
return true;
}
Shouldn't it ignore the child if it's rendered attribute evaluates to false?
