Jdeveloepr 11g 11.1.2.3.0

Question

Hi,
I am using jdeveloper 11g 11.1.2.3.0.
I have a jspx page where in all the pending contacts are displayed using a web service. I have converted the ouput text(email) to a command link which displays all the pending email id's.
When I click on the command link(EMAIL_ADDRESS) I want the link to call the pendingContacts method in the backing java bean, access the command link value and dispay it in another input text field created(P_EMAIL_ADDRESS).
Basically get the link value and set it in the input text field when clicked.
I have created a PendingContacts_action() method for the command link. However, when I run the page and click on the command link the value doesn't show in the input text field.
The code I have used is:
public String PendingContacts_action() {
try
BindingContainer bindings = getBindings();
System.out.println("In PendingContactsLink1_action");
OperationBinding operationBinding;
operationBinding = bindings.getOperationBinding("process");
System.out.println("In PendingContactsLink2_action");
String P_EMAIL_ADDRESS = null;
if (P_EMAIL_ADDRESS != null)
P_EMAIL_ADDRESS = this.getIt1().getValue().toString();
System.out.println("P_EMAIL_ADDRESS " + P_EMAIL_ADDRESS);
else {
P_EMAIL_ADDRESS = null;
System.out.println("P_EMAIL_ADDRESS " + P_EMAIL_ADDRESS);
String DISPLAY_TYPE = "EXTERNAL";
DCControlBinding cb;
cb = (DCControlBinding) bindings.get("ALL_DETAILS_ITEM");
System.out.println("In PendingContactsLink3_action");
System.out.println("cb " + cb);
Row currentRow;
currentRow = cb.getCurrentRow();
System.out.println("currentRow " + currentRow);
String EMAIL_ADDRESS = null;
if ((currentRow.getAttribute("EMAIL_ADDRESS")) != null)
EMAIL_ADDRESS = (currentRow.getAttribute("EMAIL_ADDRESS")).toString();
System.out.println(" EMAIL_ADDRESS " + EMAIL_ADDRESS);
System.out.println("In PendingContactsLink4_action");
String id;
id = (String)currentRow.getAttribute("EMAIL_ADDRESS").toString();
System.out.println(id);
Map params = operationBinding.getParamsMap();
System.out.println("params set : " + params.get("P_EMAIL_ADDRESS"));
params.put("EMAIL_ADDRESS", EMAIL_ADDRESS);
params.put("DISPLAY_TYPE", DISPLAY_TYPE);
Object result = operationBinding.execute();
catch(Exception e) {
System.out.println("In PendingContactsLink5_action");
System.out.println("IN Exception of UserPending" + e.getMessage());
System.out.println("In PendingContactsLink6_action");
this.getOt41().setRendered(false);
System.out.println("In PendingContactsLink7_action");
// this.getPanelBox1().setRendered(false);
return null;
when I run the page I get the following in the log:
In PendingContacts_action
In PendingContactsLink1_action
In PendingContactsLink2_action
P_EMAIL_ADDRESS null
In PendingContactsLink3_action
cb ALL_DETAILS_ITEM
currentRow ViewRow [oracle.jbo.Key[0 0 0 ]]
EMAIL_ADDRESS [email protected]
In PendingContactsLink4_action
[email protected]
params set : null
I don't know why I am getting the null value.
I will appreciate any help.
Thanks,
Sally

Thanks Timo. I tried to set a partial trigger on the inputText in the UI which points to the command link.
Partial Triggers - t4:c4, where c4 is the Id for the command link. I still don't see the result when I run the page and click on the command link.
I added the bit of code you provided as follows:
                String EMAIL_ADDRESS = null;
                if ((currentRow.getAttribute("EMAIL_ADDRESS")) != null)       
                   EMAIL_ADDRESS = (currentRow.getAttribute("EMAIL_ADDRESS")).toString();
                  System.out.println(" EMAIL_ADDRESS " +  EMAIL_ADDRESS);
                currentRow.setAttribute("P_EMAIL_ADDRESS", EMAIL_ADDRESS );However I got the following exception in the log after execution:
IN Exception of UserPendingJBO-25058: Definition P_EMAIL_ADDRESS of type Attribute is not found in ViewDefALL_DETAILS_ITEM4_48.
The binding that has the attribute P_EMAIL_ADDRESS is
operationBinding = bindings.getOperationBinding("process");
and the binding with attribute EMAIL_ADDRESS(the command link) is
cb = (DCControlBinding) bindings.get("ALL_DETAILS_ITEM");
I also have the following bit of code which I'm not sure is required:
                      Map params = operationBinding.getParamsMap();
                       params.put("P_EMAIL_ADDRESS", P_EMAIL_ADDRESS);  //this gives an error since P_EMAIL_ADDRESS variable is not declared.
                       params.put("DISPLAY_TYPE", DISPLAY_TYPE);
                       Object result = operationBinding.execute();Thanks,
Sally
