you can use String[] for form property

<form-property name="abc" type="java.lang.String[]"/>

 

by: KrulePosted on 2006-05-21 at 00:12:27ID: 16727039

You can also set it to an ArrayList

<form property name="abc" type="java.util.ArrayList">

ArrayList abc = (ArrayList)f.get("abc")

 

by: jaggernatPosted on 2006-05-21 at 14:25:22ID: 16730123

ok thanks.
so is it possible to find out the values which user selected from this arraylist or array?
thanks

 

by: KrulePosted on 2006-05-21 at 14:44:13ID: 16730198

That array WILL only contain the items that the user selected.
