Processing callbacks on scriptaculous forms

John Thornborrow
Hello,

I'm getting the "Component not found whilst processing callbacks" error
for a form that is rendered via scriptaculous. Am I missing something?

Root>>initialize
  super initialize.
  editor := Editor new "Editor just renders a form"

Root>>children
  ^Array with: editor

Root>>renderContentOn: html
  html unorderedList: [
    self items do: [:each |
      html listItem: [
        html anchor
          onClick: (html updater
            id: #editor;
            callback: [:ren | ren render: (editor item: each)]);
            with: 'Edit ', item description]]].

  html div id: #editor

Thanks,
John.

Re: Processing callbacks on scriptaculous forms

I'm guessing here, but it may be related to
http://www.nabble.com/Ajax-callback-question%3A-how-to-update-component-tree-before--children-gets-called--to15350231.html#a15359902

To me this was a surprising limitation on Ajax usage in 2.8. I'm holding my
fingers crossed that 2.9 has this solved but have not seen anything
definitive about it.

Yes, this is exactly the problem Sophie points out.

This is fixed in Seaside 2.9 for quite a while now.

Cheers,

Great!!

Is it ok in 2.9 for any component processing its Ajax callback to (a) cause
component structure adds/deletes/changes in distant components, and (b)
selectively call distant (re)rendering methods?

Any different protocols to be used (like the one you added as a workaround
in 2.8)? Is it OK to start using 2.9 at this point?

Thanks - Sophie

Yes, if I remember correctly.

No.

No, unless you want to find bugs.

Cheers,
Lukas
