Oracle - ADF : How to get value from select one choice not the index

    Following code stuff explain how to get value from select one choice when it is in the table's column
      
    public static Object evaluateEL(String el) {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ELContext elContext = facesContext.getELContext();
        ExpressionFactory expressionFactory =
            facesContext.getApplication().getExpressionFactory();
        ValueExpression exp =
            expressionFactory.createValueExpression(elContext, el,
                                                    Object.class);

        return exp.getValue(elContext);
    }
   
   
    Object oVal =
    ADFUtils.evaluateEL("#{row.bindings.FieldName.items['" +
                        valueChangeEvent.getNewValue() + "'].label}");

Oracle ADF : Get the selected value from SelectOneChoice not the Index;

        You can get selected attribute value using iterator for SelectOneChoice
       
        BindingContext bindingctx = BindingContext.getCurrent();
        BindingContainer bindings = null;
        bindings = bindingctx.getCurrentBindingsEntry();
        DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
        DCIteratorBinding dciter = null;
        dciter = bindingsImpl.findIteratorBinding("yourIterator");// your lookup iterator
        Object fieldVal = dciter.getViewObject().getCurrentRow().getAttribute("YourField");
        System.out.println(dciter.getViewObject().getCurrentRow().getAttribute(fieldVal));

Oracle ADF - Hot to convert upper case to input text values

-Using JavaScript
function toUpperCase(event) {
var inputField = event.getSource();
inputField.setValue(event.getNewValue().toUpperCase());
}

<:af:clientListener method="toUpperCase" type="valueChange"/>:

Or
-Using following CSS
<:af:inputText label="Hello World" id="it1" contentStyle="text-transform:uppercase;"/>:

Oracle ADF - How to iterate view object using java code

Following code stuff can be used to iterate view object without any effect to current view object.

ViewObjectImpl viewObject = getTestObject();
RowSetIterator iterator = viewObject.createRowSetIterator(null);
iterator.reset();
while (iterator.hasNext()) {
Row row = iterator.next();
// process the row here
}
iterator.closeRowSetIterator();

Oracle ADF - Another user has changed the row with Primary key

See : Chris Muir's blog : The case of the phantom ADF developer
Note : You can get above error while inserting/updating , the same entry altering using trigger or procedure. this.getTransaction().setLockingMode(DBTransaction.LOCK_NONE);

ADF - Show faces message for relevant copmonents

Using following method can show error messages for relevant component,

final int MSG_FATAL = 1;
final int MSG_ERROR = 2;
final int MSG_WARN = 3;
final int MSG_INFO = 4;
public void showMsgForRelevantComponentAll(int iSeverity, String sMsg, UIComponent uIComponent) {
FacesMessage msg = null;
switch (iSeverity) {
case MSG_FATAL:
msg = new FacesMessage(FacesMessage.SEVERITY_FATAL, null, sMsg);
break;
case MSG_ERROR:
msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, sMsg);
break;
case MSG_WARN:
msg = new FacesMessage(FacesMessage.SEVERITY_WARN, null, sMsg);
break;
case MSG_INFO:
default:
msg = new FacesMessage(FacesMessage.SEVERITY_INFO, null, sMsg);
}
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.addMessage(uIComponent.getClientId(facesContext), msg);
}

Oracle Adf - Set values to current row attribute through bindings.

Say need to set values for YourField in bean,then can try as follows

setEL("#{bindings.YourField.inputValue}","p");

//setEL implementation
public void setEL(String el, Object val) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ELContext elContext = facesContext.getELContext();
ExpressionFactory expressionFactory =
facesContext.getApplication().getExpressionFactory();
ValueExpression exp =
expressionFactory.createValueExpression(elContext, el, Object.class);
exp.setValue(elContext, val);
}
//
In pagedef you should have bindings for above attribute
<attributeValues IterBinding="YourVOIterator" id="YourField">
<AttrNames>
<Item Value="YourField"/>
</AttrNames>
</attributeValues>
