I have a bean like this:

public class MyBean{
    private String id = "";
    private String name = "";
    private Arraylist<SubClass> subclasses = new Arraylist<SubClass>();

I want to load a list of this type of beans inside a grid so that the two first cells represents the name and the id and must rowspan the size of the subclasses list. So, for every subclass in each MyBean I have to create one row.

MyBeanId  MyBeanName     SubClassCol1     SubClassCol2
--------  -----------  ---------------  ---------------
                            SC1.1.1             SC1.2.1
    1         N1            SC1.1.2             SC1.2.2
                            SC1.1.3             SC1.2.3
    2         N2            SC2.1.1             SC2.2.1
                            SC3.1.1             SC3.2.1
    3         N3            SC3.1.2             SC3.2.2

I want to do this with MVVM. Any idea of how to do it?

Thank you!


I need different rows for each children, not different cells in the same row. Something like...

<listbox model="@load(vm.myBeans)>
  <template name="model" var="myBean" children="@load(each.subclasses)>
    <template name="children" var="item">
         <listcell value="@load(myBean.MyBeanId)" rowspan="@load(myBean.subclasses.indexof(item) eq 0 ? myBean.subclasses.size : 1)"/>
        <listcell value="@load(myBean.MyBeanName)" rowspan="@load(myBean.subclasses.indexof(item) eq 0 ? myBean.subclasses.size : 1)"/>
        <listcell value="@load(item.SubClassCol1"/>
        <listcell value="@load(item.SubClassCol2"/>

zk fiddle example

But this doesn't work. I can't put a template inside a template. But I think with this example you can imagine what I want to achieve

I have updated a fiddle so you can see it in mvvm.

You just need to call the size of the list : @load(vm.list.size())

very quick without testing :

<template name="model">
    <listitem children="@load(each.sublist)">
        <listcell label="aaaa" ca:rowspan="@load(each.sublist.size())"/>
        <template name="children" var="node">
            <listcell value="@load(node.name)" style="padding-left:10px"/>

Edit :

Nothing is impossible, but it's easier if you may select the whole thing.

Look at the updated fiddle.

Thanks. But I don't know how to create the template to achieve my objective. I would need a template that goes through the MyBean list. And inside this template one that goes through the SubClass list in MyBean. So...for every MyBean I need to create as many items as subclasses in it

And the first two cells of the first line of every MyBean needs a rowspan with the size of its subclasses list

I edited my post to explain my problem

and about the selection of the listbox? need a sublist to be selected or the first list items?

The first list items. Maybe its a bit complicated for MVVM. When I select a listitem it has to reference the MyBean item, not the subclass. So...Maybe, 5 listitems makes reference to the same bean
