Accessing LOV available via methods throws No Such Property error

Question

I am using select <af:selectOneChoice> compoent (Same issue with other components too) with LOV from Model Driven data available in the following structure
Model(created as Data Control) -> findPD1(String s1, String s2) -> PD1(object of class PD1) -> findPD2(String s3) -> PD2(object of class PD2) -> List<String> itemValue
Where itemValue has get and set method.
While running I get the following error
JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-29000. Error message parameters are {0=groovy.lang.MissingPropertyException, 1=No such property: element for class: java.lang.String}
Where as, the same works if we move the itemValue under Model like
Model(created as Data Control) -> List<String> itemValue
I am using JDeveloper version 11.1.2.3 the same works fine with 11.1.1.2 is this a regression?
find some code from source below
From Page def
+<list IterBinding="testValueIterator" ListOperMode="navigation" ListIter="testValueIterator" id="testValue"+
DTSupportsMRU="true" SelectItemValueMode="ListObject">
+<AttrNames>+
+<Item Value="element"/>+
+</AttrNames>+
+</list>+
+<accessorIterator MasterBinding="findComponentIterator" Binds="testValue" RangeSize="25" DataControl="StorageModel"+
BeanClass="java.lang.String" id="testValueIterator"/>
From JSFF page
+<af:selectOneChoice value="#{bindings.testValue.inputValue}" label="#{bindings.testValue.label}"+
+required="#{bindings.testValue.hints.mandatory}"+
+shortDesc="#{bindings.testValue.hints.tooltip}" id="soc2">+
+<f:selectItems value="#{bindings.testValue.items}" id="si2"/>+
+</af:selectOneChoice>+
Please help me to fix this issue

Hi Frank,
Thanks for your help.
Here I am using the LOV using Data Control binding so #{bindings.testValue.items} itself gives the Collection of 'SelectItem'
After some analysis I reduced the problem description.
Created below two classes in model project
public class MyData  {
    private ClassOne co;
    public MyData() {
        super();
        co = new ClassOne();
        List<String> pp = new ArrayList<String>();
        pp.add("Item1");
        pp.add("Item2");
        pp.add("Item3");
        co.setPp(pp);
    public ClassOne findCO() {
        return co;
    public void setCo(ClassOne co) {
        this.co = co;
    public ClassOne getCo() {
        return co;
public class ClassOne {
    private List<String> pp;
    public ClassOne() {
        super();
    public void setPp(List<String> pp) {
        this.pp = pp;
    public List<String> getPp() {         
        return pp;
}Created the Data Control from the Class MyData ( Right click MyData class select Create Data Control -> click OK)
Drag and drop findCO() --> pp in a jsf page (in view project) --> Run --> we are getting below Exception
oracle.jbo.JboException: JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-29000. Error message parameters are {0=groovy.lang.MissingPropertyException, 1=No such property: element for class: java.lang.String}
but if we remove getCo() and setCo() methods from MyData.java then it works perfectly fine
Also this problem didn't occur on 11.1.1.6 R1 but occurs on 11.1.2.3 R2.
Not able to understand this strange behavior, please help.
Hope this is an regression issue and need to raise the bug. Please confirm.
Is there any other workaround other than removing getCo() and setCo() methods?
Thanks,
Sabareesh.
