Hello everyone,
I'm trying to make a simple tree like the example in ZkDemo : "Getting Started > Tree"
Everything is going fine from here until I tried to add a button at the end of each line in the resultGrid line.
I just try to get the click event on the "add cart button" but no matter what I do, in the @Command method "addToCart", "article" is always null !...
My zul :
<window apply="org.zkoss.bind.BindComposer"
viewModel="@id('vm') @init('nc.noumea.mairie.appock.viewmodel.ListeCatalogueServiceViewModel')"
border="none" hflex="1"
vflex="1" contentStyle="overflow:auto">
<vlayout vflex="1">
<hbox hflex="1" vflex="1">
<tree id="catalogueServiceTree" model="@bind(vm.catalogueTree)"
itemRenderer="@bind(vm.catalogueTreeitemRenderer)" width="400px" vflex="1">
<treecols>
<treecol label="Libellé"/>
<treecol label="Nombre" align="center" width="80px"/>
</treecols>
</tree>
<listbox id="resultCatalogueServiceTreeGrid" width="100%" vflex="1">
<listhead menupopup="auto" sizable="true">
<listheader label="Photo" width="100px" align="center"/>
<listheader label="Référence" sort="auto(reference)" width="150px"/>
<listheader label="Libellé" sort="auto(libelle)" hflex="1"/>
<listheader label="Colisage" sort="auto(quantiteColisage)" width="80px"/>
<listheader label="" width="55px" align="center"/>
</listhead>
<template name="model">
<listitem>
<listcell>
<image src="${each.photoSrc}"/>
</listcell>
<listcell>
<label value="${each.reference}"/>
</listcell>
<listcell>
<label value="${each.libelle}"/>
</listcell>
<listcell>
<label value="${each.libelleColisage}"/>
</listcell>
<listcell>
<button iconSclass="z-icon-cart-plus" onClick="@command('addToCart', article=each)"/>
</listcell>
</listitem>
</template>
</listbox>

@Command
public void addToCart(@BindingParam("article") Article article) {

return;
}
}
}
I'm not new to ZK and I usually find what is wrong but here I'm stuck for hours looking on forum and so...:(
Thank you for your help !
