Re: Multi-Select List Box
Can anyone post a sample? I don't know how to set the indexed properties.
If I do:
public void setSelectBox(int index, String item) {
selectBox[index] = item;
}
i can get a NullPointerException or an ArrayIndexOutOfBoundsExceptions
because I don't know selectBox array size...
What is the best practice to do it??
1. Using a Collection (is not allowed in JavaBeans specification)
2. Increasing dynamically the array size in the setSelectBox method (maybe
too tricky ?).
Thank you very much.

If you don't know for sure what the size will be, then don't use an array, use
an ArrayList. I believe the ensureCapacity() method would be used to
increase the size of the collection if the given index is larger than the
current size (-1).

Re: Multi-Select List Box
It should look like this:
private String[] selectBox = null;
public void setSelectBox(String[] selectBox){
this.selectBox = selectBox;
}
public String[] getSelectBox(){
return this.selectBox;
}
