zk grid - Get value from form of ZK -

-

i have problem zk!

this part of code:

<template name="model:group">                         <group label="@load(each)" onclick="@command('viewgraph')"/>               </template>          <!-- template each element in model -->          <template name="model" >                                   <row >                                           <label value="@load(each.hour)" />                 <label value="@load(each.value)" />                                                      </row>                                 </template>

when click on group label create graph each.hour , each.value.

the problem these value table. want graph value clicked item. possible?

the code vague, can suggest try passing through bindingparam:

onclick="@command('viewgraph', item=each)"/>

but i'm not sure how fill underlying groupsmodel
