ZK : Loading values into Selectbox from java

Question

i want to creat a selectbox to load an array of values into it.

I have written the code but the values are not loading into the selectbox so, it is empty. I think, the connection between controller and the view is incorrect. Can you please help? Thanks in advance.

                            <template name="model">
                                <listitem label="${each}" />
                            </template>
                        </selectbox>                        

                    </cell>

            </rows>            
        </grid>   
    </window>
</zk>

SalesController.java:

public class SalesController extends SelectorComposer<window> {

    private ListModelList<String> salesModel = new ListModelList<String>(SalesHeader.getSalesType());

}

SalesHeader.java:

public class SalesHeader {

        public static List<String> getSalesType() {
                return Arrays.asList(new String[]{"BU-0", "BU-1", "BU-2", "BU-3"});
        }
}

Answer 1

There are two problems:

The first error is

Property 'salesModel' not found on type [your composer class]

This is because you are missing a getter-method in your composer:

public ListModelList<String> getSalesModel() {
   return salesModel;
}

The second error is regarding the listitem element in your selectbox's template. It's causing:

Listitem's parent must be Listbox, not Selectbox

You can overcome that by simply using each or a label element in your template:

<template name="model">
    ${each}
</template>

Here you can find a working ZKFiddle example.
