Squeak 5.1和Seaside控制面板

Question

当我点击Seaside控制面板上的“浏览”按钮时，我得到了一个DNU错误。

要重现:顶部菜单->应用程序->海滨控制面板->浏览->抛出一个字典DNU #collectWithIndex：

调试器显示它发生在PluggableTreeMorph中，所以这是一个图形用户界面问题。

我正在运行Squeak5.1-16548-64bit.image

安装包的步骤如下：

 Installer gemsource
  project: 'metacello';
  addPackage: 'ConfigurationOfMetacello';
  install.

"Bootstrap Metacello Preview, using mcz files (#'previewBootstrap' symbolic version"
((Smalltalk at: #ConfigurationOfMetacello) project 
  version: #'previewBootstrap') load.

"Load the Preview version of Metacello from GitHub"
(Smalltalk at: #Metacello) new
  configuration: 'MetacelloPreview';
  version: #stable;
  repository: 'github://Metacello/metacello:configuration';
  load.

"Now load latest version of Metacello"
(Smalltalk at: #Metacello) new
  baseline: 'Metacello';
  repository: 'github://Metacello/metacello:master/repository';
  get.
(Smalltalk at: #Metacello) new
  baseline: 'Metacello';
  repository: 'github://Metacello/metacello:master/repository';
  load.


   Metacello new
        configuration: 'Seaside3';
        repository: 
    'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main';
        version: #stable;
        load: 'OneClick'.

(ConfigurationOfGrease project version: #stable) load

非常感谢您的建议。

thx

恭喜，您发现了一个bug ;) Squeak方面有了一个我们不知道的变化。我在这里打开了一个问题：https://github.com/SeasideSt/Seaside/issues/982。

对于我来说，在squeak 5.1上新安装的Seaise3中似乎可以工作的是

WARequestHandlerBrowser>>#handlersOfDispatcher:
handlersOfDispatcher: aWADispatcher

    ^ aWADispatcher isDispatcher
        ifTrue: [ | list |
            list := OrderedCollection new.
            aWADispatcher handlers keysAndValuesDo: [:key :value |
                list add: value].
            list]
        ifFalse: [#()]
