Description

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.
