Hi,
I'm working on a small blog engine, mostly to learn AIDA/Web. I've got a Blog, and some posts. In BlogApp>>viewMain, I want to display the posts : BlogApp>>vewMain |e| e := WebElement new. self observee posts do: [:each | e add: (PostApp new observee: each)]. self pageFrameWith: e title: self observee title. It does not work (return halt). What's wrong ?

What you need is to add a link to that domain object: e addLinkTo: each text: eaxh title. So, a whole viewMain would be: BlogApp>>viewMain |e| e := WebElement new. self observee posts do: [:each | e addLinkTo: each text: each title. e addBreak]. self pageFrameWith: e title: self observee title.

A solution would be to rewrite this in BlogApp>>viewMain in a block, but I don't want to duplicate my code. That's why I wrote in BlogApp>>viewMain "e add: (PostApp new observee: each)".

That's why I wrote in > BlogApp>>viewMain "e add: (PostApp new observee: each)". Then try to put that e from PostApp>>viewMain in a separate method like #introElement and then in BlogApp simply call: e add: post webApp introElement. But this is a bit hackish kind of reuse IMHO and I never do that way. If I really want to make a reusable part of web page, I make a special component (as subclass of WebElement) and reuse it elsewhere. But in your case it is just simpler to replicate that code in PostApp. Best regards Janko -- Janko Miv?ek AIDA/Web Smalltalk Web Application Server http://www.aidaweb.si |
