Trying to figure out a way to do the following without much luck.
I have an enumeration with a list of menu options and corresponding labels such
as:
public enum Color {
RED("Red"),
BLUE("Blue"),
GREEN("Green");
private String myLabel;
private Color(String label){ this.myLabel = label; }
public String getLabel(){ return this.myLabel; }
}
This can be easily used to create a checkboxlist:
<p> Please enter your favorite colors: </p>
<s:checkboxlist
list="@my.site.enums.co...@values()"
listValue="label"
name="colors"
/>
I also have a set of Color on the Action that came from the persistence layer
and has a Color for each of the user's (past) choices:
public Set<Color> getColors() {
return colors;
}
Question is: How do I automagically "check" the appropriate checkbox if they
have a corresponding value in getColors? I guess I'm looking for something like
a databind from other languages.
I suppose one could iterate over the enum and create individual checkboxes for
each while testing to see if they have an already selected color, but I thought
there might be a more direct way...
