Subject [jira] [Commented] (TOMAHAWK-1607) focus cannot locate targets inside UIData elements
Date Wed, 04 Jan 2012 01:48:40 GMT

    [ https://issues.apache.org/jira/browse/TOMAHAWK-1607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179218#comment-13179218

Mike Kienenberger commented on TOMAHAWK-1607:
---------------------------------------------

Previous workaround left UIData in an inconsistent state causing unexpected issues.   New
version resets rowIndex and uses UIComponentPerspective to represent state.

> focus cannot generate correct clientIds for targets inside UIData elements because UIComponent.findComponent()
does not preserve row index information.
> I noticed this in my legacy 1.1.6 app, but I suspect after glancing at the latest Tomahawk
1.1.9 code that the problem still persists.
> However, I don't know how much focus is really used anymore -- it never made it out of
the sandbox, and ajax makes doing much of this a lot easier now.
> I created a workaround for focus by reimplementing a local version of findComponent()
in a custom focus subclass and this workaround will work, except in those cases where a parent
component had customized findComponent() behavior which I will attach to this issue.
> A more modern solution would likely be to dump findComponent for invokeOnComponent which
correctly sets the rowIndex.
