Leonardo Uribe commented on TOMAHAWK-1056:
------------------------------------------
use the same id for different components is invalid, so the code of
findComponent it is fine and it is not a problem with tomahawk. f:param could
have the same name but always different id. This issue will be closed as
invalid.
> With multiple commandlinks with same child-component id, tomahawk will always
> find the first commandlink's child component

> Affects Versions: 1.1.6
> Environment: Linux Ubuntu Feisty Fawn 7.04, MyFaces 1.1.5, Facelets
> 1.1.11, ajax4jsf 1.1.1, richfaces 3.0.1

> <ul id="language" style="float:right;">
> <li>
>
> <t:commandLink id="changelocale_en"
> style="color:blue;" value="English"
> actionListener="#{profileBean.changeLocale}">
> <f:param id="locale" name="locale_1" value="en"/>
> </t:commandLink>
> </li>
> <li>
> <t:commandLink id="changelocale_nb"
> style="color:blue;" value="Bokmål"
> actionListener="#{profileBean.changeLocale}">

> actionListener="#{profileBean.changeLocale}">
> <f:param id="locale" name="locale_3" value="nn"/>
> </t:commandLink>
> </li>
> </ul>
> This code works. however when finding child by ID, the child of the first
> t:commandlink returns.
> UIParameter param = (UIParameter)
> evt.getComponent().getChildren().get(0);
> // UIParameter param = (UIParameter)
> evt.getComponent().findComponent("locale"); // Always returns
> // the child of the first <t:commandLink
> String locale = String.valueOf(param.getValue());
> Locale loc = new Locale(locale);
> JSFUtil.getFacesContext().getViewRoot().setLocale(loc);
