reRender on click of RadioButton shows Blank Page
I am unable to reRender the values on the click of RadioButton . It shows
blank page
Here is the code snippet
[code]
<div style="overflow:auto; width:85%; height:125px">
<h:dataTable id="deviceDetailTable" styleClass="list"
rowClasses="odd,even"
value="#{updateDeviceBean.tableRows}" var="vartableRow"
>
<h:column id="column1">
<a4j:region>
<t:selectOneRadio id="interfaceId"
value="#{updateDeviceBean.deviceInterface.id}" >
<f:selectItem itemLabel="" itemValue="#{vartableRow.id}" />
<a4j:support
action="#{updateDeviceBean.loadDeviceInterfaceDetails}" event="onclick"
reRender="interfacePanel" />
</t:selectOneRadio>
<h:message for="interfaceId" />
</a4j:region>
</h:column>
<h:column/>
<h:column/>
</h:dataTable>
</div>
<a4j:outputPanel id="interfacePanel" >
<h:panelGrid columns="3" styleClass="detail" columnClasses="label">
<h:outputLabel><h:outputText value="MAC" />
</h:outputLabel>
<h:inputText id="mac"
value="#{updateDeviceBean.deviceInterface.mac}" />
<h:message for="mac" />
<h:outputLabel> <h:outputText value="Status" />
</h:outputLabel>
<h:selectOneMenu id="status"
value="#{updateDeviceBean.interfaceStatus}" >
<f:selectItem itemLabel="" itemValue="" />
<f:selectItems
value="#{updateDeviceBean.interfaceStatusList}" />
</h:selectOneMenu>
<h:message for="status" />
</h:panelGrid>
</a4j:outputPanel>
[/code]

Re: reRender on click of RadioButton shows Blank Page
Posted by David Delbecq <de...@oma.be>.
several remarks:
1) each of your radio buttons will be in separated groups, because their
id will be different (something like
form:deviceDetailTable:x:interfaceId) where x is row number. You'd
better have a <f:selectItems
value="#{someBean.somePropertyThatGenerateList}"> and remove that datatable.
2) the reRender value of your a4j:support (interfacePanel) does not
resolve to any existing component because there is no component named
form:deviceDetailTable:x:interfacePanel. See docs of a4j and docs on
UIComponent.findComponent() refered to by a4j docs.
3) Check a4j is properly configured and your generated xhtml is valid.
Use 'limitToList="true"' to ensure your don't get a blank page that
replace existing in case of failure, check for javascript error message,
check for server message, sniff the wire to see the XmlHttpRequest
response from server.
