Attempt to create & implement a domain which may hold ArrayList SelectItem

Question

IDE used - JDeveloper 11.1.1.3
Hi,
I tried to create a new domoan with the following class
*public class SelectItemList implements DomainInterface, Serializable {*
private ArrayList<SelectItem> array;
private ArrayList<SelectItem> lst;
*public SelectItemList(ArrayList<SelectItem> val) {*
lst = val;
validate();
*protected SelectItemList() {*
lst = new ArrayList<SelectItem>();
*public ArrayList<SelectItem> getData() {*
return lst;
** <b>Internal:</b> <em>Applications should not use this method.</em>*
public void setContext(DomainOwnerInterface owner, Transaction trans,
*Object obj) {*
** Implements domain validation logic and throws a JboException on error.*
*protected void validate() {*
*// ### Implement custom domain validation logic here. ###*
*public String toString() {*
*if (lst != null) {*
return lst.toString();
return null;
*public boolean equals(Object obj) {*
*if (obj instanceof DomainInterface) {*
*if (lst != null) {*
return lst.equals(((DomainInterface)obj).getData());
return ((DomainInterface)obj).getData() == null;
return false;
*public ArrayList<SelectItem> getArray() {*
return this.lst;
Domain XML
<?xml version="1.0" encoding="windows-1252" ?>
<!DOCTYPE Domain SYSTEM "jbo_03_01.dtd">
<!---->
<Domain
xmlns="http://xmlns.oracle.com/bc4j"
Name="SelectItemList"
Version="11.1.1.56.60">
<DesignTime>
<Attr Name="_type" Value="java.util.ArrayList"/>
<Attr Name="_isPersistent" Value="false"/>
<Attr Name="_isQueriable" Value="true"/>
<Attr Name="_isUpdateable" Value="true"/>
<Attr Name="_columnType" Value="VARCHAR2(500)"/>
<Attr Name="_isCodegen" Value="true"/>
<Attr Name="_isSelected" Value="true"/>
</DesignTime>
</Domain>
In the ViewRowImpl Class I am initializing the value of a transient Attribute of type SelectItemList
I have an EL which binds to a SelectItems which is a child of SelectOneChoice contained in a table column.
*value="#{row.bindings.SpecialBodyPartList.array}*
This however does not work. The dropdown does not show any values.
If I use the same class in my managed bean & bind it to the SelectItems then I see the correct results.
Am I missing out something?
Thanks,
Prakash

Hi Prakash,
I have a very similar business requirement. Can you please help me in this.
This is the structure in which I need the return type for my service interface's custom method.
<xsd:element name="output">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="UseCaseId" type="xsd:string" minOccurs="1" maxOccurs="1"/>
<xsd:element name="ActivityType" type="xsd:string" minOccurs="1" maxOccurs="1"/>
<xsd:element name="ActivitySubType" type="xsd:string" minOccurs="1" maxOccurs="1"/>
<xsd:element name="SiebelInputParams" minOccurs="1" maxOccurs="1">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Status" type="xsd:string" minOccurs="1" maxOccurs="1"/>
<xsd:element name="Assignee" type="xsd:string" minOccurs="0" maxOccurs="1"/>
<xsd:element name="ExpirationTime" type="xsd:string" minOccurs="0" maxOccurs="1"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="WebPageParams">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Assignee" type="xsd:string" minOccurs="0" maxOccurs="1"/>
<xsd:element name="ExpirationTime" type="xsd:string" minOccurs="0" maxOccurs="1"/>
<xsd:element name="RequestXSLT" type="xsd:string" minOccurs="0" maxOccurs="1"/>
<xsd:element name="ResponseXSLT" type="xsd:string" minOccurs="0" maxOccurs="1"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
So, I created ABCViewObject (Rows populated programmatically ,not based on sql query ) and then created viewAttributes accordingly to get the above xsd structure.
ABCViewObject
AttibuteName                                 DataType
UseCaseId String
ActivityType String
ActivitySubType String
SiebelInputParams model.util.SiebelInputParameters
WebPageParams model.util.WebPageParameters
I made my method to return List<ABCViewRowImpl> type. That was fine. I could see the method available, in the list of 'Custom methods' while creating service interface.
But the problem is, after I select the type for the 'util.List' of my return type for my custom method, I could not proceed to 'Next'. The error I get is
'Java Type model.util.model.util.SiebelInputParameters referenced by SiebelInputParams is currently not supported'
Kindly help me in this regard.
