another hitch in the tutorial..

i am step four, and almost have things working..

the part i am having trouble with is:

StListComponent>>#renderContentOn:

renderContentOn: html

html table: [(self sortBlock
value: (self filterBlock value: self items))
do: [:item | html tableRow: [self renderItemBlock
value: item
value: html]]].

no matter what i do, i keep getting the following error:

UndefinedObject(Object)>>doesNotUnderstand: #value:

after this:

[] in StListComponent>>renderContentOn: {[(self sortBlock value: (self
filterBlock value: self ite...etc...

i think i am out of places to look..

any help would be appreciated ..

thanks!

Re: another hitch in the tutorial..

Hi Sergio,

The message "self sortBlock" is an access to the instance variable sortBlock. So you try to send value: to exactly this instance variable but it seems not to be defined. Try to check if you forgot to define the value of sortBlock.

Peter

Hello Sergio,
Look at StRoot>>initializeListComponent (about three paragraphs below the code you posted in the tutorial). Of course, the sortBlock instance variable needs to been defined for StListComponent as well.as its accessor methods. Then you need to call this method in StRoot>>initialize

Warm regards

hmm.. it seems like this is okay.. here is the declaration of my class:

WAComponent subclass: #StListComponent
instanceVariableNames: 'items filterBlock sortBlock renderItemBlock'
classVariableNames: ''
poolDictionaries: ''
category: 'STTutTodoApp'

i did a refactor, and sortBlock and sortBlock: both appear in
StListComponent's declaration..

digging further.

thanks!

i am DETERMINED to hang in there with seaside this time..

hmm.. here is my StRoot>>initialize

initialize
super initialize.
self
initializeMenuComponent;
listComponent: StListComponent new.

this seems like it should be okay, yeah?

thanks!

i needed to do:

initializeListComponent
