Problem a4j:support for h:selectOneRadio in JSF

843844Jul 11 2010 — edited Jul 14 2010
Hi All,

I Need to Hide/Show the outputpanel when i select one option from <h:selectOneRadio> using a4j:support.
By default Date output panel is hidden but when yes option is selected it should be displayed and vice versa using ajax support. 
 <h:selectOneRadio id="radio1Id" value="#{bean.options}" valueChangeListener="#{bean.onChange}">  
<f:selectItem itemLabel="Yes" itemValue="Yes" />  
 <f:selectItem itemLabel="No" itemValue="No" />  
 <a4j:support event="onclick" reRender="PanelDate" />  
 </h:selectOneRadio> 

<a4j:outputPanel id="quater" ajaxRendered="true" rendered="#{bean.displayDate}">
	<h:outputText value="From" styleClass="OuputText"/>	
	</a4j:outputPanel>

private boolean displayDate;
public void onChange(ValueChangeEvent event){			
		HtmlSelectOneRadio radio=(HtmlSelectOneRadio) event.getComponent();		
		System.out.println(radio.getValue());		
		if(!radio.getValue().equals("3")){
			setDisplayDate(true);
		}
	}
But the problem is entire page is getting refreshed instead of panel.
Please help me in resolving this issue.

Thanks in Advance.
Kriss

Hi,

I'm trying to make heterogeneus connection, but when edited listener.ora return this error:

TNS-01201: Listener cannot find executable /app/oracle/product/11.2.0/db_home2/bin/oracle for SID ORCL

Any suggestions?
(PROGRAM=dg4odbc)
give fully qualified pathname for PROGRAM

Yes, you may need to wait up to 1 minute for database instance automatic registration. If you don't want to wait, you need to run for each database instance:
alter system register;

Hi,
What is your ORACLE_HOME?

is it

/home/oracle/app/oracle/product/11.2.0/dbhome_2

or

/app/oracle/product/11.2.0/dbhome_2

????

The listener log implies the first one but the parameter file implies the 2nd one?

Cheers,
Harry

Hi again,
The top comment line of your listener.ora implies it is located in db_home1 but you are starting the listener from dbhome2. If there is no config at all then a default config will be started up. This looks like what might be happening make sure the listener.ora is located in the correct ORACLE_HOME.

Cheers,
Harry

Hi again,
Is LD_LIBRARY_PATH all on one line or spread over 3 lines it looks like it is 3 lines that should all be joined together?

Cheers,
Harry
