Using Enums with HashMaps and xhtml access

seamuser111 Sep 9, 2009 2:53 AM

Hi, I am having trouble accessing a map from xhtml that contains an Enum type as key. Since Seam can convert enums to strings I assumed going the other direction, String -> Enum conversion would work also, however I am not able to use it. Example code:

public enum MyType { ONE, TWO }

public Map<MyType, String> getTest() {
    Map<MyType, String> m = new HashMap<MyType, String>();
    m.put(MyType.ONE, "3333");
    return m;
}`

On xhtml

#{obj.test['ONE']}

This displays null. If I change the key type MyEnum to a String, things work fine. Any suggestions?

You need to create a getter method in a bean:

@name("enums")
public class Enums() {
   public MyType getONE() {
      return MyType.ONE;
   }
   public MyType getTWO() {
      return MyType.TWO;
   }
}

on xhtml
#{obj.test[enums.ONE]}

Have a good one!
