What I've used for this kind of problem is save the scroll position to the cookie(not the<br>
anchor label but the "real scrollbar position" using Javascript).<div><div></div><div class="h5"><br>

I try to see the difference facet of the problem regarding mix use of<br>
composition and the scroll problem. May be my view is partial because I<br>
don't know much javascript, but here it goes:<br>
<br>
So far, I see mainly 3 concomitant issues:<br>
<br>
1. when you call a sub component, the canvas scrolls back to the top<br>
<br>
2. when you return from a sub component, the canvas scrolls back to the<br>
top<br>
<br>
3. when you click a link with a callback changing the state of the<br>
canvas, it scrolls back to the top<br>
<br>
Regarding the history of the comments in this mailing list, I see the<br>
problem can be solved using anchor.<br>
<br>
But the problem is far to be optimal as it breaks reusability of the<br>
component.<br>
<br>
For issue #1, I try with a special Anchor decoration, with this render<br>
method:<br>
renderContentOn: html<br>
html anchor<br>
name: anchor;<br>
script: (SUScript new goto: '#', anchor). <br>
html text: ''.<br>
self renderOwnerOn: html.<br>
<br>
Don't ask me why the html text: '', otherwise the anchor is rendered<br>
toward the end of the component (is it because the component has the<br>
Form decoration?).<br>
<br>
The decoration does not solve entirely reusability because the #answer<br>
message in the sub component is out of the reach of the decoration. So<br>
you still need to subclass component to get the scroll back issue #2<br>
fixed, for example I sub-class WAChoiceDialog to override method ok:<br>
ok<br>
self session jumpToAnchor: anchor .<br>
super ok<br>
<br>
Not nice<br>
<br>
<br>
For issue #3, it is quite simple:<br>
html anchor<br>
callback: [attribute pushVersion: 'votre texte'.<br>
self session jumpToAnchor: self hash asString];<br>
with: '( + )'.<br>
<br>
Any comments or additional ideas?<br>

Hello,<br>
<br>
Are there a well known pattern for seaside to deal with the browser<br>
scrolled page when using sub-component and callback?<br>
