I've got to finish this up soon, and I am stumped.
Again, sorry for the length - I just want to be clear.
I have a form that need to collect some information about a user, using checkbox groups like so:
Bourbon
[] Jim Beam
[] Makers Mark
[] Blantons
Scotch [] Johnnie Walker [] Macallan [] Lagavulin
Beer [] Budweiser [] Heineken [] Duvel
Users can select 0 or more from each category, and I would like to use multibox to create the checkbox groups.
I created a HashMap of String[]s like so:
public HashMap getDrinksList() {
drinks = new HashMap();
drinks.put("Bourbon", new String[]{"Jim Beam","Makers Mark","Blantons"});
drinks.put("Scotch", new String[]{"Johnnie Walker","Macallan","Lagavulin"});
drinks.put("Beer", new String[]{"Budweiser","Heineken","Duvel"});
}
In my ActionForm I have:
private HashMap drinkPrefs = getDrinksList();
private String[] selectedDrinks; public String[] getSelectedDrinks(String key) {
if(drinkPrefs.containsKey(key)) {
return (String[]) drinkPrefs.get(key);
} else {
return new String[]{};
}
}
public void setSelectedDrinks(String key, String[] selDrinks) {
drinkPrefs.put(key, selDrinks) ;
} In my jsp I have:
<c:forEach var="drinkType" items="${drinksList.keySet}"><!-- there is wrapper method for .keySet() -->
<h3><bean:write name="drinkType"/></h3>
<c:forEach var="drinkItem" items="${drinksList[drinkType]}">
<html-el:multibox property="selectedDrinks[${drinkType}]">
<bean:write name="drinkItem"/>
</html-el:multibox>
<bean:write name="drinkItem"/>
</c:forEach>
</c:forEach>
I would expect to get a list of checkbox groups like I laid out above, but instead I get:
java.lang.IllegalArgumentException: Invalid indexed property 'selectedDrinks[Bourbon]' at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUt ils.java:404)...etc etc.
What am I doing wrong? Where can I get more detailed information about multibox and indexed properties?
