Was trying to implement a popup panel with validation. To execute the portion only in the panel, it was in a a4j:region.
The problem was, it appeared that validation was failing and re-rendering was not occuring, so messages would never occur.
setup - netbeans 8.02, Jsf2.2, richfaces4.5.5.
partial code for illustration (could not figure out how to format properly code snippet with editor)
<a4j:region id="regiongroup" >
|<h:message for="email2id" />|
<a4j:commandButton value="Accept a4j:"
render works for @ all, form, and for the thisPanel id.
this appears to be related to
however, the reason that I was using @region was it is listed in 4.3 Partial view updates as a valid rendering area, even in the latest doc
The region that contains the requesting component is updated. Use the <a4j:region> component as a wrapper element to specify regions.
So the questions are - should region be renderable, or should it be struck from the documentation?
anyway, the discrepency led to much lost time and hair tearing out
you already have a4j:outputPanel in there which is the correct container for rerendering, use that. I will change the documentation.
(You can format code if you switch to advanced editor, then look for ">>" in the menu)
