Leonardo Uribe commented on MYFACES-702:
----------------------------------------
I checked it and the code comes from other issue:
https://issues.apache.org/jira/browse/MYFACES-454
It is probably this is valid on 1.1.x branch (due to its inner portlet code).
This was a hack that comes from pre portlet-bridge times (note in that time the
solution for portlets was use myfaces and its custom generic portlet). In
portlet-bridge, the portlet specific UIViewRoot implements NamingContainer, so
its clientId is appended to all generated ids implicitly.
You're right, Michael, this issue should be fixed on 1.2.x and 2.0.x branches
(I think there are some code in tomahawk that requires it too). I'll close
MYFACES-702 and MYFACES-454.

> We have a JSF app that runs as a portlet and normal webapp.
> In the webapp the <h:outputText value="some text"/> appears as I would expect
> (i.e. just the text) however the same thing in the portlet gets rendered as:
> <span id="form-id:handleMetaDataEvent_id36">some text</span>
> This becomes a problem when you are trying to use outputText to render part
> of a URL or to become a JavaScript string as the output includes the span
> element!
> Looking at the renderer code for outputText it appears the span gets
> generated when the id does not start with "_id", so the question is where has
> the "handleMetaDataEvent" prefix for the id come from?
