I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
<logic:iterate id="restaurant" name="favoriterestaurants">
...
<html:multibox property="favoriteRestaurantRemoveList">
<bean:write property="restaurantId" name="restaurant"/>
</html:multibox>
...
</logic:iterate>
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.
