Thanks Leonardo,
Already done, but I have another question:
Which is the reason that UIComponentBase.findComponent(String expr) looks for
the searched component, starting from the closest parent that implements
NamingContainer?
Look at this example:
<h:outputText id="text" value="#{bean.texto}"></h:outputText>
<ui:repeat id="repeat" value="#{bean.textos}" var="texto">
<h:commandLink id="command" value="#{texto}">
<f:ajax event="click" listener="#{bean.actionListener}" render="text"/>
</h:commandLink>
</ui:repeat>
If we try to render this view, we get:
javax.faces.FacesException: Component with id:texto not found
This exception is trown by HtmlAjaxBehaviorRenderer.mapToString when he find
every component identified in the render attribute. I think they converts the
id's in the render attribute, to the clientId of every component referenced.
The problem is that UIRepeat implements NamingContainer, so the commandLink
inside that UIRepeat is gonna search the component identified by 'text' inside
the children list of repeat tag.
But it should works, isn't it? Nothing wrong to re render an outputtext from
command link that is inside a repeat.
I have reimplemented method findComponent in my own components, in order to
find the id starting from the view root... and it works.
Is this another bug?
Regards,
Ricard

Asunto: Re: UIRepeat offset and size problem
Hi
It is a bug. Please create an issue here:
https://issues.apache.org/jira/browse/MYFACES
I have already a patch, so as soon as you create the issue I'll commit
it. Later, you can get a nightly build snapshot here:
