a4j:support doesn't work on h:selectOneRadio

[user080701]

Hi,

The a4j:support doesn't work. When the user change the radio button, the valueChangeListener method will set the myBean.showAddress.

<h:selectOneRadio id="devption" value="#{myBean.option}" layout="pageDirection" valueChangeListener="#{myBean.valueChanged}">
<f:selectItem itemValue="0" itemLabel="#{msg.option_one}"/>
<f:selectItem itemValue="1" itemLabel="#{msg.option_two}"/>
<a4j:support event="onchange" ajaxSingle="true" id="dummy_id" reRender="address"/>
</h:selectOneRadio>

<h:panelGrid id="address" border="0" columns="2" rendered="#{myBean.showAddress}">


Has any missing on my code?

i think event should use onclick for radiobutton

[user080701]

I changed to onclick, but it still doesn't work!

The ajax works on a4j:commandLink,
<a4j:commandLink action="#{cart.delete}" reRender="cart,cartno">
<h:outputText value="Delete" />
</a4j:commandLink>

Has any idea?

Hi,

I change to disable the components in the panelGrid instead of rendered on panelGrid and it works.
e.g.

<h:selectOneRadio id="devption" value="#{myBean.option}" layout="pageDirection" valueChangeListener="#{myBean.valueChanged}">
<f:selectItem itemValue="0" itemLabel="#{msg.option_one}"/>
<f:selectItem itemValue="1" itemLabel="#{msg.option_two}"/>
<a4j:support event="onchange" ajaxSingle="true" id="dummy_id" reRender="address_line1"/>
</h:selectOneRadio>

<h:inputText id="address_line1" label="#{msg.address_line1}" required="true" disabled="#{!myBean.showAddress}"></h:inputText>

It seems that we cannot rerender the component to make it invisible via ajax. Is it right?

reRender some component with rendered attribute is not a good idea. read about a4j:outpoutPanel layout="none", there are the answer.

It doesn't work!

I follow the doc to change my code
<a4j:support event="onclick" reRender="mypanel"/>
...

<a4j:outputPanel layout="none">
<h:panelGrid border="0" columns="2" id="mypanel" rendered="#{not myBean.showAddress}">
....

The panelGrid haven't hidden when sesct the radio button.

Please help!

Oh! I know the reason.

It is because the components <h:selectOneRadio> and <h:panelGrid> is located in another outer <h:panel>.

When I re-render the outer <h:panel>, the hide/show effect is working now.

Thanks
