Buttons and actions

Hi list,

although I have experience with Seaside and made couple of application  
with it, I'm completely beginner in Aida world. I must say, that  
Aida's concept looks pretty interesting and for dozens of webapps is  
much more suitable than Seaside.
Ok, back to my question. I have followed tutorial on http://www.aidaweb.si/tutorial 
  and everything works fine...Oh maybe in last section (7. Enhance the  
table) is IMO small typo in:

column: 3 addBlock: [ :each |
                        (WebElement new) addLinkTo: each text: each surname].

should be:

column: 3 addBlock: [ :each |
                        (WebElement new) addLinkTo: each text: each lastName].

After completed tutorial, I tried to improve some details by myself  
and here I went into troubles. I want button 'Back' in the view of  
address in class ADemoAddressApp alongside the implicit button 'Edit'.  
So I added method:

ADemoAddressApp>>actionBack
        self redirectTo: self observee parent

changed method:

ADemoAddressApp>>actionEdit
        self redirectToView: #edit

and made changes in:

ADemoAddressApp>>viewMain

        ...here goes original code from tutorial...
        ...
        e addButtonText: 'Edit' action: #edit.
        e addButtonText: 'Zpět' action: #back.
        self style pageFrameWith: e title: 'Address'


After this "improvements", nothing is happen no matter if I click on  
Edit or Back. What I'm doing wrong, please?

Thanks
Martin

Hi Martin,

I'm just preparing a ToDo example to show the another and currently the
strongest dimension: highly ajaxified and realtime so called single page
apps. What you saw in tutorial is a traditional but still very needed
approach. Combined with single page one you come to the biggest strength
of Aida.

Super, just corrected, thanks!

Change method name to #actionMainBack

And change this method name to #actionMainEdit.
As you see action method names are composed by convetion as
'action'+viewname+action(optional). That's why #actionMainBack.

Let me add an error report if such method is not composed correctly and
therefore missing...

Best regards
Janko

You're welcome, I'm pleased I could help.


Thanks a lot. Now it's clear to me and everything woks well. I must  
catch the overall 'spirit' of Aida, because I just started to dicover  
it, but I must say, it quite impressed me.

Regards
Martin
