[jira] [Commented] (WICKET-4881) IE 8 : error when handling Wicket Ajax Response

["Didier Villevalois (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-4881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580614#comment-13580614 ] 

Didier Villevalois commented on WICKET-4881:
--------------------------------------------

I'm a bit annoyed by the commit that fixes this bug: https://github.com/apache/wicket/commit/cbf76d0e8c355876e302699c0975971773941ae9
I understand that this is needed for IE compatibility but, indeed, it does completely removes the possibility to use the notify callback in the evaluated Javascript code. (see: https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js#L1045)

I would need that to defer DOM replacements after a modal window close animation.

We can keep the IE-needed concatenation of evaluations by adding some Java APIs to:
1) Explicitly ask for a particular script to be in its own "[priority-]evaluate" element (just like IJavascriptResponse does for appended-scripts)
2) Pass an additional string to name the notify callback name

May I open a feature request issue for that, or should I use this bug as its fix broke an existing feature ? I can provide patches.

> I have a problem with Wicket 6.2.0/6.3.0 and IE (this works perfectly with Chrome or Firefox). I have a list of items, with Ajax links in the list. The response to the Ajax link modifies a panel from the page, and redraws the list (its container).
> IE does at least some of the changes correctly, but outputs an error, and it seems that subsequent Ajax request fail:
