Re: T5: Loop and ArrayList

[Nick Westgate]

The loop assigns each successive item to the value you give.
So for each iteration (item in the list) it will try to call:
setCurrentMember(Member member)

You need to provide such a member and set/get methods in Java:
private currentMember;

Then inside the loop you can refer to it using prop notation:
${currentMember.name}

Cheers,
Nick.

Hi,

I searched list for a while and can't find solution to this, so will just
post it here:

I have an ArrayList of a class and I need to access it from the loop, here
is the code in java:

 public class Member {
        private String name;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public Member() {
            this.name = "member";
        }
    }

    private ArrayList newMembers = new ArrayList();


 public ArrayList getNewMembers()
    {
        return newMembers;
    }

  public Member getCurrentMember(int index)
    {
        return (Member)newMembers.get(index);

    }

here is the template, it seems not right:
<t:loop source="NewMembers" value = "CurrentMember" index="i" >
    // how to display the name of each member here ?
</t:loop>
