How to build 2 linked list

[asfer...@gmail.com]

It's urgent

Hi all,

first list --> categorie1
second list --> categorie2 (populate by the categorie selected value)

Could you tell me why i have this message --> Cannot invoke method setModel() on null object
when i select a categorie1 option

GSP code

<zkui:select name="categorie1.id" id="categorie1" from="${vdo.catapp.Categorie1.list()}" optionKey="id" />
<zkui:select id="categorie2" optionKey="id"/>
Composer Code

Window self
Combobox categorie1
Combobox categorie2
void onChange_categorie1(Event e) {
def categories2 = Categorie2.where("categorie1.id = "+categorie1.selectedItem.value)
ListModelList lm = new ListModelList(categories2)
categorie2.setModel(lm)
}

Thanks !
