selectItems and converter

["Walter Oliver (BR/ICI3)" <ol...@boschrexroth.de>]

Hi all,

just a question about using SelectItems and converter. 


I have the following code:

<h:selectOneMenu id="levelFilter" value="#{commands.levelFilter}"
valueChangeListener="#{commands.filter}" onchange="submit()"
converter="levelConverter">
	<f:selectItems value="#{commands.levelList}" />
</h:selectOneMenu>


and in my Bean:

public List<SelectItem> getLevelList() {
    	
	List<SelectItem> levelList = new LinkedList();
		
	for(int i = 0; i <= level; i++) {
		levelList.add(new SelectItem(i));
	}
    	
	return levelList;
}


So far it looks good, but on client side i get:

<option value="Level 1" selected="selected">0</option>
<option value="Level 2" selected="selected">1</option>
....

Instead of expected

<option value="0" selected="selected">Level 1</option>
<option value="1">Level 2</option>
....



Any idea to get the options name and value get turned around?

Regards Oliver

Use the SelectItem constructor for label *and* value:
SelectItem(java.lang.Object value, java.lang.String label)

This way you can specify both value of the option tag and the label
displayed to in the dropdown.
