[jira] Commented: (MYFACES-1891) ClassCastException in converter
when Hiding / Showing unselected selectOneRadio
[ https://issues.apache.org/jira/browse/MYFACES-1891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619363#action_12619363 ]
Leonardo Uribe commented on MYFACES-1891:
-----------------------------------------
Suppose this scenario
<h:form id="form">
<h:commandButton value="#{hideShowBean.hidden? 'Show' : 'Hide'}"
action="#{hideShowBean.toggleHideShow}" immediate="true" />
<t:div id="hideableBlock" rendered="#{!hideShowBean.hidden}">
<div><h:selectOneRadio id="selectOneRadio"
value="#{hideShowBean.property}">
<f:selectItem itemLabel="Option Z" itemValue="" />
<f:selectItem itemLabel="Option A" itemValue="1" />
<f:selectItem itemLabel="Option B" itemValue="2" />
<f:selectItem itemLabel="Option C" itemValue="3" />
</h:selectOneRadio></div>
<div><h:inputText id="inputText" required="true" /></div>
</t:div>
<h:messages />
</h:form>
According to the spec (see MYFACES-1759), itemValue="" is equivalent to null, so when you hide and show several times, the result should be the same (Option Z selected).
To be according to the spec, on myfaces core 1.2 RendererUtils.NOTHING should be removed and used null instead. But on myfaces core 1.1 this spec does not enforce us, so to remain compatibility this solution is acceptable. But we need a patch against 1.1

> When the block with the selectOneRadio ist shown, then hidden and then shown again a ClassCastException occurs in the Converter. The selectOneRadio has as submittedValue org.apache.myfaces.shared_impl.renderkit.RendererUtils$1, for which the conversion is done.
