Transient Attribute not updating the value from dropdown ADF

• One reason could be List of Values doesn't match the type of the Attribute in Transient View Object ( Type Mismatch )
• Make sure you update Transient Attribute as "Always" updatable

Get the current selected value in the backing bean on ValueChangeListener() of SelectOneChoice ADF

 

public void valueChanged(ValueChangeEvent valueChangeEvent) throws Exception{

valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance());

DCBindingContainer bindings =

(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();

DCIteratorBinding iter =

bindings.findIteratorBinding("CountryTRVOIterator");

CountryTRVORowImpl countryRow= (CountryTRVORowImpl) iter.getCurrentRow();

System.out.println(countryRow.getCountryId());

}

or

public void valueChanged(ValueChangeEvent valueChangeEvent){

OperationBinding oper1 = ADFUtils.findOperation("GetHyperLinkEWP");

if (JSFUtils.resolveExpression("#{bindings.ActionRef<attribute_in_bindings>.selectedValue.attributeValues[1]}").toString().equals("Compliant")) {

oper1.getParamsMap().put("BindLabel", "Approval Report");

System.err.println("Approval Report");

} else {

oper1.getParamsMap().put("BindLabel", "Rejection Report");

System.err.println("Rejection Report");

}

oper1.execute();

}

or

if you are trying to get the new value of the select one choice before the value gets updated to model

public void valueChanged(ValueChangeEvent valueChangeEvent) {

this.setValueToEL("#{bindings.Deptno.inputValue}", valueChangeEvent.getNewValue()); //Updates the model

System.out.println("\n******** Selected Value: "+resolveExpression("#{bindings.Deptno.attributeValue}"));

System.out.println("\n******** Display Value: "+resolveExpression("#{bindings.Deptno.selectedValue ne ' ' ? bindings.Deptno.selectedValue.attributeValues[1] : ''}"));

}
