Re: enumerated type and f:selectItems

2007-05-23 Thread Erlend Hamnaberg 

Here is a custom localized selectItem creator from enums.
Assumes you have a resource bundle configured in faces config.

It also expects values for each Enum Value.

If you have this enum:

package com.exampe;

public enum Example {
   EXAMPLE
}

Then the appropriate entry in the message bundle would be:

com.example.Example.EXAMPLE=example


   public static ListSelectItem 
createSelectItemsFromEnum(FacesContext context, Class? extends Enum 
value) {

   ListSelectItem list = new ArrayListSelectItem();
   Application a = context.getApplication();
   String msgBundle = a.getMessageBundle();
   Locale locale = context.getViewRoot().getLocale();
   ResourceBundle rb = ResourceBundle.getBundle(msgBundle, locale);

   Set? extends Enum set = EnumSet.allOf(value);
   if (set != null  set.size()  0) {
   for (Enum e : set) {
   String name = value.getName() + . + e.name();
   list.add(new SelectItem(e, rb.getString(name)));
   }
   }

   return list;
   }

I have also a Converter that uses the same method from and to Enums if 
you'd like that. That is needed if you use standard components.

RE: enumerated type and f:selectItems

2007-05-23 Thread Beelen, Marco 
Hello all,

I'm using a slighty different alternative.
I added the method getLabel to my Enum, which returns the key of the
property for that value of Enum.

My page contains a the following scrap:

h:selectOneRadio 
layout=pageDirection
value=#{createRequestBean.category}

t:selectItems 
value=#{createRequestBean.availableCategories} 
var=category 
itemLabel=#{labels[category.label]} 
itemValue=#{category} /

/h:selectOneRadio


In my managed-bean I just return a ListEnum with all values from my
Enum like this:

/**
 * Gets the available categories.
 * 
 * @return An array with all the available categories.
 */
public ListCategory getAvailableCategories() {

Category[] categories = Category.values();
return Arrays.asList(categories);
}
 
Combined with a generic converter for Enums and a getter and setter for
the Enum on my managed-bean it works like a charm for me.

With kind regards,
  Marco Beelen

Re: enumerated type and f:selectItems

2007-05-22 Thread eric . jung 
Thanks! If I understand correctly, this converter is for the variable 
which is value-bound to a UIOutput/UIInput-derived classes (e.g. 
UISelectOne), but not for UISelectItems. In other words, is there a way to 
get f:selectItems/ to output options for all values of the enumerated 
type? I tried:

f:selectItems value={#MyClass.selectItems/

public MapMyEnum, String getSelectItems() {
  MapMyEnum, String selectItems = new EnumMapMyEnum, 
String(MyEnum.class);
  for (MyEnum o : EnumSet.allOf(MyEnum.class))
selectItems.put(new Integer(o.ordinal()), o.getName());
  return selectItems;
}

and a few variations on that, without any success.
