Locked

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
Stack Trace
I hope it's quite clear. Thnx for help _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

hi,
Have you defined/declared menu as an instance variable in class Site (I hope thats the class n ame for the first set of code). It would be clear if you can provide that info. The error you have got is due to the fact that the method children ^ Array with: menu is not triggered properly. Update if you still encounter any problem, Hope that helps, Rajeev On Dec 29, 2007 5:48 PM, an organic <

Hi,
WAComponent subclass: #Site instanceVariableNames: 'head menu' classVariableNames: '' poolDictionaries: '' category: 'Pom' children ^ Array with: self head with: self menu initialize super initialize. head := Head new. menu := Menu2 new. Is this info better? But from menu2 in renderContentOn i call next Class WMenuItem which i want use to render my items. When i render items direct in menu2 component it works fine. But i want learn render items in next component (because items are hierarchical structure and WMenuItem can work recursively) When i write render i think write in html to website ;). I thought that problem is here: menu2 dont have dynamically created WMenuItem in his children array. But i am not able to add it into this array (children of menu2). When i change code renderContentOn of Menu2: renderContentOn: html | temp | html unorderedList: [items do: [:item | temp := WMenuItem new. self children: self children, temp. html div class: 'a'; with: (temp kategorie: item) ]] i get this error: Error: Instances of WMenuItem are not indexable2007/12/29, Rajeev Lochan <[hidden email]>:
