Have you tried adding ItemListener? this should work....
<CODE>
jpanel extends JPanel implements ItemListener
private JRadioButton;
public jpaenl()
rad = new JRadioButton("myradiobtn");
add( rad )
rad.addItemListener( this );
public void itemStateChanged( ItemEvent e )
if( e.getItemSelectable() == rad )
//todo code here

How to capture "Click" or "MouseOver" actions of SelectOneChoice.

Hi All,
I want to show a popup with some text + hyperlink when user either clicks or mouseover the selectOneChoice.
I can't use ShortDesc because the tooltip contains a hyperlink as well.So i created a method in managed bean and raising a popup using that.
Right now i used below.But it's triggers only if there is a value selected and that too if there is a change in value.
But i wanted it whenever we just click on SelectOneChoice and need not necessarily select anything.
<af:selectOneChoice label="Testing" id="soc1" autoSubmit="true" valueChangeListener="#{RamaBean.test}">
Thanks,
Sid.

Hi,
I am new to ADF Faces,May be i am not getting your solution.
The selectOneChoice is not allowing to place the ServerLsitener inside it.So coded as below.
It's not working.Can you take a look.

How to prevent error message for material description in MDG material detail screen, when user click on check action

Dear Experts,
I have a requirement for making material description as non mandetory in change request view of mdg material screen.
I have done that using field usage in get data method of feeder classes, but still message is displaying.
This message 'Material description is mandatory is displaying with check action only, but not with save or submit after i anhance field property as not mandetory.
How to prevent error message for material description in MDG material detail screen, when user click on check action.
Thanks
Sukumar

Hello Sukumar
In IMG activity "Configure Properties of Change Request Step", you can completely deactivate the reuse area checks (but will then loose all other checks of the backend business logic as well).
You can also set the error severity of the checks from Error to Warning (per CR type, not per check).
Or you provide a default value for the material description, e.g. by implementing the BAdI USMD_RULE_SERVICE.

How to change images based on action.Even clicking changed images should ?

how to change images based on action.
Even clicking changed images should do respective actions.
and while displaying only one image at a time sholud get displayed.
I am using three images for a single column of a table in Jsp.
Any clues.
Any link for any good javascript html jsp site where i can find some good solution.
vijendra

In broad way if i say i have multiple situations in mutiple tables where i need such a logic to operate in for all tables.
lets say in first time load of page by default one image will be displayed (one with sorted order for first column rest all non sorted)Now after every click to any image respective sort should get called.along with all images should get changed.Here with every function one/two images will get effect at least.
As in first if i say sort by desc then this image will change rest all will remain in unsort form.
when i move to other column and click on new image the previos will convert to unsort and new one will convert to sort by ascending. rest all will be in unsort form as it is.
Now it seems like same logic is required with two three conditions.
even for everyaction different parametrs has to be passed at differnt situations.
Any good idea if someone can suggest.
I will be very greatful for him.
thanks
vijendra

How to catch menu click events from B1AddOn Wizard

Thank you for attention
Massimo

Thank you Eddy,
I had a look at the help, but there it is not explainsed that events can be attached only to string menus!!
It was attempting to do something wrong.
A further question: is it possible to add new menus and related events to an existing project (I tried with new item and then B1 Addon Component, but it doesn't let me add new menus)?
Thanks again

How to catch and display a link content in another portlet page?

Can you tell me how to display a URL content into next page after an user click s on this link? I am developing a JSR 168 portlet under a Portal. I have 3 pages so far in my portlet. view.jsp, view2.jsp and IpByHourPage.jsp. view2.jsp displays a lis of IP address. When an user clicks on an IP in view2.jsp, it goes to IpByHourPage.jsp. How to catch the IP address such as 123.23.89.21 that an user just click displayed in IpByHourPage.jsp. I don't know why I got null value returned.
Also, I don't know how to do a "go back to previous page". I want to go back to view2.jsp from IpbyHourPage.jsp
Here is my code
in view2.jsp
<portlet:renderURL var="aURL">
<portlet:param name="goto" value="IpByHourPage"/>
</portlet:renderURL>
<a href="<%=aURL.toString() %> "><%=MyIP%></a>
in IpByHourPage.jsp
<%
String MyIPHour = request.getParameter("goto");
%>
<h1>IP Report by Hour ( <%=MyIPHour%> )</h1>
<portlet:renderURL var="Ret_IPByHour">
<portlet:param name="Ret_IPHourPage" value="Ret_IPByHourPage"/>
</portlet:renderURL>
<center> <a href="<%=Ret_IPByHour.toString() %> "><b>Choose Another IP</b></a></center>
in my .java file
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException, UnavailableException {
response.setContentType("text/html");
String MyBegDate = request.getParameter("BegDate");
String MyEndDate = request.getParameter("EndDate");
String MyNetworks = request.getParameter("networks");
String MyYourName = request.getParameter("yourname");
PortletURL renderURL = response.createRenderURL();
renderURL.setPortletMode(PortletMode.VIEW);
request.setAttribute("renderURL", renderURL.toString() )
String GotoRenderAction = request.getParameter("goto");
String MyIPHourAction = request.getParameter("Ret_IPHourPage");
if ( (MyIPHourAction!=null) && MyIPHourAction.equals("Ret_IPByHourPage") )
PortletRequestDispatcher kk = getPortletContext().getRequestDispatcher("/view2.jsp");
kk.include(request, response);
if (MyIPHourAction != null && MyIPHourAction.equals("Ret_IPByHourPage"))
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/view2.jsp");
mm.include(request, response);
if (GotoRenderAction != null && GotoRenderAction.equals("IpByHourPage"))
request.setAttribute("BegDate", "MyBegDate");
request.setAttribute("EndDate", "MyEndDate");
System.out.println("BegDate" + MyBegDate);
System.out.println("Endate" + MyEndDate);
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/IpByHourPage.jsp");
mm.include(request, response);
if(MyEndDate!= null )
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view2.jsp");
prd.include(request, response);
else if (MyEndDate==null && GotoRenderAction == null)
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view.jsp");
prd.include(request, response);
The problem for above code is the clicked single IP can not be displayed in IpByHourPage.jsp. and I cannot go back to view2.jsp from IpByHourPage.jsp. when I click "Choose Another IP"
I find out that the MyBegDate and MyEndDate values are all null when I click Choose Another IP link. I got the following error message
Caused by: javax.servlet.ServletException: Unparseable date: "null null"
     at org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:858)
     at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:791)
     at org.apache.jsp.view2_jsp._jspService(view2_jsp.java:651)
     at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
How to fix above problems. Thanks

I think the problems are related to portletsession. But I don't know how to use it. How to put portletsession into doview method or my jsp pages. Can anyone tell me in my code? Thanks a lot.

I'm wanting to use the "Actions" in Photoshop Elements 11. But when I get the Actions box up, it is only showing a small list of effects to use. And no side bar to go any further. When I click on the little arrow at top and then click on "load actions"

I'm wanting to use the "Actions" in Photoshop Elements 11. But when I get the actions box up, it is only showing a small list of effects to use. And no side bar. So I can't go any further. When I click on the little arrow at top and click on "load actions", I am only getting a box with empty space saying "No items match your search". The folder at the top does say "Actions". How do I get more effects? The tutorials that I've checked into all show a long list of effects in their box. Can anyone help?

To use the existing actions, try the following:
1. Open one of the Action Sets, in this example Special Effects is the Action Set, by pressing the small arrow beside the set name.
2. Then click on the name of the Action, in this example Faded Ink is the Action name.
3. Then press the Play button to run the action.

How to Disable the Lead selection Action on aTable n How to Refreh a Page

HI....
1)How to Disable the Lead selection Action on aTable n How to Refreh a Page r web dynpro application.
In my case i have a table n user enters data on multiple rows in table , n i have some input fields outside of table for those Inputs fields am settiing the data at the screen initilization(in Init() moethod by hard code).the problem is whenever the is clicking in th 2nd row of a table the Lead Selection is triggerig and the data in the Input Fields outside the table is not displayinig.
So by removing the lead Selection Action of a table i thought i can reslove this,
2) How to refresha page(like we click F5 on key board),is it can be done thru code in web dynpro application
Regards
Rajesh

Hi,
You did not explained what is your functionality or coding in leadselection. Is that action on leadselection is necessary for you?.
1)If you just want to remove the action then go to table properties and remove the action for leadselection.
2)If you still want to continue with your leadselect action, then what you can do is.. write the code in leadselection action to again set the input fields which are out from table. That is what you did in your init method.
Page Refreshing
3) What do you mean by page refreshing? is that refreshing your table only or both the table and input fields.
What I understood is you are allowing the user to enter values in table and soon after pressing a button the values should be saved and the data in input fields shld be deleted. For this if you only invalidate the node then the user entered data will be lost.
So what you do is after getting the input data from the user add it to a ArrayList and then invalidate the node which clears the data in input field. Finally bind the Arraylist to your node. see the following code. This is a concept make changes according to your requirement
ArrayList list1=new ArrayList();
wdContext.nodeAbc().bind(list1);
IPrivateExcelviw.IAbcElement ele = wdContext.createAbcElement();
ele.setNo(wdContext.currentAbcElement().getNo());
ele.setName(wdContext.currentAbcElement().getName());
ele.setMarks(wdContext.currentAbcElement().getMarks());
list1.add(ele);
wdContext.nodeAbc().invalidate();
wdContext.nodeAbc().bind(list1);
Revert me if you have any doubts

How to catch the ApplicationStart event??

how to catch the application start event??
i want to do some actions (Java code) that will be run once when the application started
this like ApplicationStart event in ASP.NET
how ???

Google for javax.servlet.ServletContextListener. You need to write a class that implements this interface and register it in web.xml.
Please ask questions like this in the JDeveloper or OC4J forum since they are not related to JHeadstart.
