Hello,
i am new with seaside and i want make this demo:
class Site root component:
children
^ Array with: self menu
renderContentOn: html
html div class: 'site'; with: [
html div class: 'menu'; with: self menu.
]
initialize
super initialize.
menu := Menu2 new.
+canberoot and accessors for menu
class Menu2 instance variables: items
initialize
super initialize.
items := OrderedCollection new.
items
add: (Item new value: '1').
items
add: (Item new value: '2').
items
add: (Item new value: '3')
renderContentOn: html
html
unorderedList: [items do: [:item | html div class: 'a'; with:
(SubMenu new item: item) ]]
class Item instanceVar value
renderContentOn: html
html text: value.
WAComponent subclass: #SubMenu
instanceVariableNames: 'item itemEditor'
classVariableNames: ''
poolDictionaries: ''
category: 'Pom'
editItem: aItem
self itemEditor item: aItem copy.
(self call: self itemEditor)
ifTrue: [aItem copyFrom: self itemEditor item]
initialize
super initialize.
itemEditor := ItemEditor new.
renderContentOn: html
html
listItem: [html text: ' a ' , self item value.
html anchor
callback: [self editItem: self item];
with: 'e']
and itemEditor, i think editors is fine.
i think problem is in menu2 when i create new object subMenu because when i
click on 'e' and i want edit item i get error:
Possible Causes
- you do not implement #children correctly
- you do not backtrack #children correctly
- you do not implement #states correctly
