WATree redraw

Hello,

With WATree, each time a node is unfolded pressing the +, the web page
is entirely updated and scrolled back at the top (as it is usual). From
an usability point of view this is kind of catastrophic, especially when
you have long tree, longer than the screen height. Do some of you know
some solution to fix that behaviour?

Thanks

Hilaire

To scroll to the right place, you need to have an <a name="anchorname"></a>
and the fetched page must fetch http:/......#anchorname, so it's *possible*,
but it's gonna take some work.

SUTreeReport from the Scriptaculous package.

The component is very useful to browse a tree.
I need to add callbacks to the elements of the first row in the tree.
When a link is hit a report is displayed in another component (a
WATableReport). But again at this moment the page is recomputed so back
to the top of the screen. I will try Randal suggestion, this should be
workable.


competencyTree := SUTreeReport  new
        roots: (Array with: (IFIModels competency: 6));
        children: [ :competency | IFIModels linksTo: competency ];
        addColumn: [ :competency | [:html  | (html anchor)
                navigation;
                attributeAt: 'title' put: competency title;
                callback: [self selectCompetency: competency];
                with: (competency title truncateWithElipsisTo: 50) ]]
           label: 'Notions';
        yourself

Well, you can also use a simple AJAX updater action.

html anchor
     onClick: (html updater
         id: 'nameOfDiv'l;
         callback: [ :r |
             self selectComp: comp.
             self renderComOn: r ];
         with: comp title

Cheers,
Lukas

Thanks a lot.
