[jira] Commented: (TAP5-558) Create modal dialog component

["Ulrich Stärk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835158#action_12835158 ] 

Ulrich Stärk commented on TAP5-558:
-----------------------------------

That progressive display part is a bit tricky. Right now you can simply place a ProgressiveDisplay inside a dialog but the contents will be loaded right away, regardless of whether the dialog is visible or not. That seems to me to somehow contradict the purpose of a dialog. The content should only be loaded when the dialog is shown. Since there is no event we can observe to trigger the loading only when the progressivedisplay is visible, we would have to trigger the update from inside the dialogs javascript code and that will make changes to the Tapestry.ZoneManager and ProgressiveDisplay necessary.

The other alternative would be to reimplement progressivedisplays functionality as part of the dialog component (which isn't much, thankfully).

There will be similar problems with the dialog acting as a kind of formfragment, though.

What do you think?

> Tapestry's AJAX support is missing one important component, modal (or non-modal) dialog. Dialog could be created with http://www.wildbit.com/labs/modalbox/ or http://roland.devarea.nl/dialog/ or http://github.com/robhurring/prototype-dialog/ or http://livepipe.net/control/window
> After quick look first one looks like most professional.
