[ANN] Aida/Web 6.0 second beta is out!

Dear Smalltalkers,

That time with a considerable more fresh meat and on both Squeak+friends
and VisualWorks, a second beta of Aida/Web 6.0 web framework and
application server is released.

To download it visit our renewed website http://www.aidaweb.si

With that beta we also changed the direction: now the 6.0 won't be just
a companion of Scribo CMS but a standalone release with support of
tree-like control flow, so that this release will really deserve a major
number jump from 5.6 to 6.0.

Here are just 3 most important new features in that beta:

  1.Introduction of web execution contexts as a step towards tree-like
    control flow. These contexts give a scope to the "execution" of web
    request and are the precondition for controlling this flow of
    execution.

  2.Translation support for text on the web apps, to allow the
    multilingual text on the pages, besides multilingual content,

  3.Caching (memcached like) to improve performance of serving the
    content, which otherwise doesn't change frequently.

But much more in release notes: http://www.aidaweb.si/release-notes-6.0.html

Best regards
Janko Mivšek

Hi Janko,

I just spent a few minutes playing around with the new beta
in a VW (prerelease) and found a problem while trying to
grant access rights to a newly created user.

And right now I noticed something else...

Add a new user, go to the users page and click on the
link for the new user. The url is

        http://localhost:8888/user/.html

which will be fun to deal with if I add a second user ...

Now on the user page, I click on "Access rights" at the bottom
of the page and then click on item 5 of the application list,
WebDemoControlFlowApp

The yes/no links for "all views" and "all encrypted" work as expected,
however, when I try to toggle the setting for "confirmation" (first row),
the new state ends up with "main" (second row). Trying to toggle the
first row again, does not change, so I think that it is actually the wrong
property being updated here.

Trying to click on"yes" for "all encrypted", I end up with a MNU for
AIDASite>>sslPort.

Regards,
s.

Janko,
I have loaded 6.0 beta 2 and have the following discoveries:

1)    each of my sites now takes me to the admin login page.
2)    I had changed 'cookieName' on my sites - this led to a problem where I got a blank page with "request for unknown or nonexistent context! " Either removing my cookieName or reloading my original extensions both worked. Presumably related to setting a context for the request.
3)     various references to 'self app' needed to be changed to 'self site style' -  you had warned about that.

There are some css type things to tidy up but otherwise so far so good.  :-)

There seems to be a stricter requirement for css. For instance I had previously defined a border as '550' whereas now I must use '550px', similarly I had a colour defined  without using the '#' prefix. Such examples worked okay previously but failed with Beta 2.

Security Manager has been refactored - leading to some problems with my extensions (and perhaps explaining Stefan'c comment.

The WebGrid modifications no longer work. I have not had time to explore yet, but I suspect it might be because of the use of context and block passing - we will see.

I was too busy to work on it (and will be tomorrow) so earliest
tomorrow evening on the train I can work on it. I've done the analysis
but I believe I got a defective installation so it's not working right
now.

At least at the weekend I will give it a second try. It was obvious
why it couldn't work but the modifications where few and
straightforward.

My WebGrid application works now, with the following modifications to the changes proposed by Alex and Herbert:

WebApplication >>

respondToAjaxRequest: aRequest
    | oldElement e ajaxForm|
    ajaxForm := aRequest context form. ....

ajaxDoBlock: ajaxForm
...  
    block := (ajaxForm context elementId: elementId)
                otherAt: blockName
                ifAbsent: [^self]. ...

WebElement >>
....
    viewParm := 'view=', ajaxForm view asString.
    versionParm := 'version=0'. ....

This last change was prompted because with "version = '' ", the javascript contained a double '&&' and the filter did not work. I do not have versioned pages so am not able to test whether there are any further ramifications for this change.

ok I managed to have my app running on 6.0 beta2. Migration was not as
straightforward as just installing the new Aida, but maybe that was
me.

For Squeak I attach the changed methods as fileouts, for VW copy them
from the end of this mail.

only thing regarding my app is, that a selected Tab in ViewTabs is not
highlighted any more.

I will look into it maybe tonight.

Hi ,


HK> only thing regarding my app is, that a selected Tab in ViewTabs is not
HK> highlighted any more.

HK> I will look into it maybe tonight.

in ViewTabs>>prepareTabsList the original ifTrue: is commented out and
replaced with a link like in the not selected case.

I'm only guessing here: the css of a link somehow supersedes the
tab1selected css, as that's what can be seen in Firebug. The purpose
might have been to refresh the selected tab when it's clicked on?

Anyway as this also affects WebDemoApp>>gridTabsElement I replaced it
with the old line which remedies both.

Seriously: should we have a bugtracker?
