ADF SelectOneChoice List Question

Toplink Essentials List Question
==================
I am new to Toplink Essentials. I am using Toplink Essentials inside of JDeveloper 11g, against Oracle Express and ADF/Trinidad and have used JDeveloper's "Entities from Tables" wizard to reverse engineer my database into Toplink pojo objects. After this I used JDeveloper's wizard to create a JavaServiceFacade and then generate a Data Control.
After expanding the DataControl (which is mapped to the JavaServiceFacade) I have a method queryEntityFindAll(). Under this method I have serval attributes and then a list which represents a "many-side" of this entitie's relationship with another entity. How do I create a selectOneChoice using this list?
I've tried expanding queryEntityFindAll() and then dragging the list to a jspx page, setting the Base Data Source to "JavaServiceFacade.queryEntityFindAll.listName and then setting the List Data Source to "ListName : JavaServiceFacade.queryRelatedEntityFindAll". However, when I run the page the only thing that appears on the page is the selectOneChoice label... no drop down component appears on the page... no errors are generated to give any clue as to what my problem may be...
Although I'm working in JDeveloper, I really believe this is a Toplink Essentials question...
Please help!

Thanks for the quick response!
Using the department / employee example... I'm trying to create a form that allows a user to create a new department. I have dragged the "Department" object (located under queryDepartmentFindAll()) over to my jspx form. A form with corresponding fields is created.
I notice that no field was created for employeeId. I expand the "Department" object (again, under queryDepartmentFindAll()) and observe that "Employee" is present, as a list (expanding Employee provides access to employee object attributes along with another list entitled departmentList).
I know that it's unlikely that only one employee would be selected in the creation of a department... but I'm sticking to the example...
So, I drag the "Employee" (again, under queryDepartmentFindAll()) object over to the newly created form and from the pop-up menu I choose selectOneChoice as the desired component. I run the jspx page, Internet Explorer 7 browser pops up and all labels display on the page, all fields but no selectOneChoice component appears on the screen... the space is there for it but it appears to be invisible. I have checked the Employee table and there is data to be displayed... it's just that I must be missing something...

Reading text file and display in the selectOnechoice list item In ADF.

Hi,
I have a requirement to read the text field which have list of strings and that string display in the SelectOneChoice List item component on page load.
I am using Jdeveloper 11.1.2.3 version.
Any suggestion will highly appreciated..
Thanks in advance.

Hi,
Google will produce you with hints on how to read content of a file from Java (ideally the file uses some delimiter). Then in a managed bean, you read the file and save its content in a list of SelectItem. So your managed bean should have the following property and setter/getter pairs
ArrayList<SelectItem> listFromFile = new ArrayList<SelectItem>();
public void setListFromFile(ArrayList l){ //you don't need this }
public ArrayList<SelectItem> getListFromFile(){
   //read file content and iterate over the file list entries
for(i=0, i < fileContent.length, ++i){
     SelectItem si = new SelectItem();
     si.setValue(... the value to update the list of value with ...);
     si.setLabel("... the label to show in the list ...");
     listFromFile.add(si);
return listFromFile;
}The af:selectOneChoice component should look as follows
<af:selectOneChoice id=".." value="...attribute to update with selection ..." ...>
   <f:selectItems value="#{managedBean.listFromFile}"/>
</af:selectOneChoice>Frank

Bind the output data (Xml) from BPEL process to ADF SelectOneChoice Control

Hello,
My requirement is to invoke a BPEL process from ADF page and display returned results in a select one choice (drop down box).
I have created a Data Control for the BPEL process through Web service data control and tried to invoke the BPEL process. I could see from the BPEL console that BPEL process is getting invoked. But the ADF doesn't bind any of the output to Select one choice.
It doesn't even show any error.
Can you plz help me how to bind the output of the BPEL process to ADF SelectOneChoice control.
The Xml Which I recieve from BPEL process is
<outputVariable><part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload"><DBConnectDemoProcessResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.oracle.com/DBConnectDemo">
<StatusTrans xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<transId>1</transId>
<fromStatus>Open</fromStatus>
<toStatus>Assigned</toStatus>
</StatusTrans>
<StatusTrans xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<transId>2</transId>
<fromStatus>Open</fromStatus>
<toStatus>Pending</toStatus>
</StatusTrans>
<StatusTrans xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<transId>3</transId>
<fromStatus>Open</fromStatus>
<toStatus>Closed</toStatus>
</StatusTrans>
<StatusTrans xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<transId>4</transId>
<fromStatus>Open</fromStatus>
<toStatus>Cancelled</toStatus>
</StatusTrans>
</DBConnectDemoProcessResponse>
</part></outputVariable>
And the toStatus node values viz, Assigned, Pending, Closed, Cancelled should get binded to the SelectOneChoice control
Waiting for your valuable inputs,

babloo.

I have been still trying for the solution. I have modified the XSD created by the jdeveloper to,
<schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/StateTransitions"
     xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="StateTransitionsProcessRequest">
          <complexType>
               <sequence>
               <element name="input" type="string"/>
               </sequence>
          </complexType>
     </element>
     <element name="StateTransitionsProcessResponse">
          <complexType>
               <sequence maxOccurs="unbounded">
<element name="stateChanges">
<complexType>
<sequence>
<element name="fromState" type="string" />
<element name="toState" type = "string" />
</sequence>
</complexType>
</element>
</sequence>
          </complexType>
     </element>
</schema>
And I have given this XSD url while creating the Web Service Data Control by deploying it into the Oracle App server.
So, I can see the tree structure of "Return" as "StateTransitionsProcessResponse->StateChanges->toState,fromState"
I have binded the toState field of the Data Control to the SelectOneChoice ADF control in a jspx page by using List binding editor.
I have selected,
Base data source as "Variables" (Currently I don't need to update any table),
List Data source as "process: getStateTransitions.process.StateTransitionsProcessResponse.stateChanges" (Web Service Data Control)
Base Data source attribute as "process_input"
List Data Source Attribute as "toState"
I can initiate the web service (BPEL process) by providing the necessary input value like 'Open' or 'Pending' or 'Assigned' but the SelectOneChoice control doesn't populate with any values.
Waiting for valuable inputs!
Thanks and Regards,
babloo.

ADF selectOneChoice filtering - Oracle ADF mystics

Hi clever guys,
I wanna filter a selectOneChoice component based on the value of another component using JUCtrlListBinding.filterList(..) in the managed bean (onValueChange)
based on Frank Nimphius' article
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/90-filter-adf-bound-lists-508190.pdf]
Say my selectOneChoice contains 10 rows with different pointId attribute - POINTA, POINTB, POINTC.
If we filter on pointID, which is contained only in 1 row, then the filter returns all the rows - filtering is not applied. As soon as a specific pointID is contained at least in 2 rows, the filtering works and only these rows are returned.
Say we display selectOneChoice with attributes productId and pointId. Rows, before filtering, are like this
- PRODUCT1, POINTB,
- PRODUCT2, POINTA,
- PRODUCT3, POINTB,
- PRODUCT4, POINTC,
- PRODUCT5, POINTC,
- PRODUCT6, POINTB,
- PRODUCT7, POINTC,
If we tell JUCtrlListBinding.filterList() to select only rows with POINTB or POINTC, it works fine (returns 2 resp. 3 rows), because they are contained in 2 or 3 rows. If I filter on POINTA, all rows (7) are returned (filtering is not applied). As soon as I insert 1 more row for POINTA, it works.
My code snippet>
JUCtrlListBinding listBinding = (JUCtrlListBinding) bindings.get("productId1");
listBinding.getDCIteratorBinding().getViewCriteria().clear();
HashMap m = new HashMap();
m.put("pointId", selectedPointId);
listBinding.filterList(m);
I write out the contents of listBinding values with System.out... just before and just after the filterList method, that's how I can see that this method behaves like that.
Guys, do you have any idea on what could go wrong and how to workaround it?
Thanks a lot.

Problem Using a Bind Variable on a SelectOneChoice List VO

Hi everyone,
I have a List View Object on my application that contains the lookup values for some combos. The underlying table has three columns: LOOKUP_TYPE, LOOKUP_CODE and DESCRIPTION. It is used like this: when i want to find out which are the possible values for the "Customer Status" field on a form, i need to execute this VO with LOOKUP_TYPE = "CUST_STATUS". when i want to find the Supplier status, i execute it with "SUPP_STATUS". Then i compare the value of LOOKUP_CODE with the customer_status or supplier_status codes to get its description.
The problem is, i have to use this VO as the Dynamic List of values for a SelectOneChoice. I have correctly mapped it, but the VO query is like this:
SELECT lookup_code, description FROM tab_lookup_codes WHERE lookup_type = :lkpType
So i need to set the bind variable dinamically, as i would do with ExecuteWithParams, but for a SelectOneChoice list. How can i do such thing? is there a way to define a value for this parameter before ADF executes the List VO on the page definition, or even programatically?
If you didn't understand my requirement, please let me know.
Thank you very much for your time!
Thiago Souza

Hi Thiago,
If i understand you problem you can try to insert a invokeAction to your page definition with refresh property equals prepareModel that call a method that sets your Where param propertly. In this way your method will be executed before prepareModel.
I haven't test this, its only a possible idea.
Best Regards

ADF SelectOneChoice Refresh

Hi all,
I want to know how to refresh a combobox (id=c2) and syncronize it with databindings.
When i change the value of my other combo (id=c1) (with autosubmit=true) i have in my bean this to try to refresh my combo (id=c2)
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("ExecuteWithParams"); //over viewobject that is used by c2
Object result = operationBinding.execute();
AdfFacesContext adfContext = AdfFacesContext.getCurrentInstance();
adfContext.addPartialTarget(c2);
I also have in my pagedef this
<invokeAction id="invokeCombo2" Binds="ExecuteWithParams"
Refresh="always"/>
The thing is that combo data is filtred and it looks like as i wish ....
but i realize the data is out of sync with my values.
Imagine that i have in my c2 this pairs value/text:
value1/text1
value2/text2
If my combo c1 filters c2 to just show text2 what happens is that text2 cames with value1. wrongly.
What is not syncronizing?

I went thru the same issue about 2 months ago.
Short version is if your calling this in the backing bean then the value you are using the previous value of c1. You don't need to do this if you have the partialTriggers property of c2 set to c1. It will automatically refresh c2. But there's a catch if the value of c1 is not sequential 0,1,2,3,4... then you need to place the field used by c1 on the page again and set the renderd propert to false (usually will gets the name <field_name>1). Now in your ExecuteWithParms set the param value to <field_name>1. This is because if you look at the values returned by the SelectOneChoice it's the index value (0,1,2,3..) not the actual value.
For more deatil on this you can look at a blog by Duncan Mills

Hi,
in the pageDef ile, select the iterator for this list and set the fetch size to -1 (its 10 by default)

To set default to the selectOneChoice list

Hi Experts,
I have a small problem in setting the default value as <No selection> to the selectOneChoice list.
Though I added unselectedlable as <No selection> to the selectOneChoice List its taking first value from the List instead of <No selection>.
The values of the selectOneChoice is binded to the ViewObject.
Please anybody help me in setting the default as <No selection>.
Thanks & Regards,
Veeresh

<af:selectOneChoice label="#{bindings.VwObj_OrgId1.label}"
binding="#{backingBeanScope.backing_jsp_pages_Login.selOne_choice}"
id="selOne_choice"
autoSubmit="true"
partialTriggers="p1"
simple="true"
immediate="true"
*value="#{bindings.VwObj.inputValue}"*
unselectedLabel="<No selection>">
<f:selectItems value="#{bindings.VwObj.items}"
binding="#{backingBeanScope.backing_jsp_pages_Login.si1}"
id="si1"
/>
</af:selectOneChoice>
The select one choice's value is set with #{bindings.VwObj.inputValue}.
How do you expect to see the 'No selection' label?
Remove the value="#{bindings.VwObj.inputValue}" from the selectOneChoice -- you would see the 'No Selection' label.
The 'No Selection' label is only shown if the LOV's value is NOT set.
Thanks,
Navaneeth

ADF selectonechoice valuebinding called twice

Does anyone have any idea why the valuebinding method of an ADF SelectOneChoice component would be called twice? I have one drop down with values and when I select something in that drop down the valuebinding for the second drop down is called twice, when it should only be called once. Any help would be appreciated.

Hi,
what is the refresh setting of the region binding in the page's PageDef file? Put a print statement to the task flow initializer to verify the region is executed twice

ADF selectOneChoice and af:forEach

Hi,
I'm atempting to create a data-bound selectOneChoice that displays DepartmentName and selects the corresponding DepartmentId as its value. I've tried using an af:forEach on an f:selectItem with the selectOneChoice, but I'm getting an error with the EL refernces that the the row refernces aren't valid.
Could anyone provide some insight?
Thanks,
Debojit

Thanks for the prompt reponses.
Hi Suresh, Rodrigues and Vinod,
I'm attempting to build my selectOneChoice from the Department table table directly, without code in between AND get back real values for the selections I make, so I'm afraid I can't use any beans, at least not for pouplating the drop-down list.
Hi Navaneetha,
I tried your approach, but I'm still getting a "Refrence not Found" error for the EL refernce "#{row.DepartmentName}" , and the drop down is coming up as empty when i run the page.

Where I can define the order by for a dynamic SelectOneChoice list

Hi
I am using JDeveloper 10.1.3.1-Toplink/POJO for the DataModel and ADF JSF for disigned the web pages.
My problem is that I can not find the way to order the element of a dynamic SelectOneChoice.
Can anyone help me please?
Thanasi

Hi,
Not tested yet, but the order should be define in the method that retrieves the list values. You can specify an argument on this method and pass it in e.g. via a EL reference

Maximise Task Pages in iFrame popup Window when opened From ADF Task List

All,
We have built a custom worklist application that implements the Out of the Box Task list ADF Task flow. For application reasons, we have disabled the preview window (bottom section of task list) by using the Task Flow paramters.
When navigating from the tasklist, it launches a new browser window for the applicable task.FYI the browser url seems to take the pattern of that below.
http://<Server>:8001/LVWorkspace/faces/__ADFvDlg__?_adf.ctrl-state=fpkt030re_18&_vir=/LVWorkspace/faces/adf.dialog-request%3F_adf.ctrl-state%3Dfpkt030re_18&loc=en-US&_minWidth=750&_minHeight=600&_rtrnId=1355238885906&_afrLoop=1204852572759076&_afrWindowMode=1&_afrWindowId=ADFDialog10
My question is is it feasible to control the size of this window? It allows seems to open a set size. The ideal would be to maximise the window to a full screen. This would save the users having to do this manually. Does anyone know if this is feasible? Or have any ideas suggestions for items you have done to perform similar functionality.
Any help would be appreciated to see if this is feasible.
FYI, we are using SOA/BPM 11.1.1.6.3
Many Thanks
Dave

Hi,
Sorry to reply to my own threads. If anyone doesn't have a resolutin for this, has anyone experienced issues like this with your own custom workspaces?
Also in IE, when the tasklist page is closed (prior to it launching completely) the workspace reamins in model form.
Has anyone experience this issue?

ADF View objects question

Hello,
I created a view object (which bases on an entity object) that I'd like to use for searching for records in a table called "CARS". Cars will be searched by names. I also have a JSP page for adding cars (administration functionality).
The situation is as follows:
1. I go to the page for adding cars and click "Submit" (which only submits data without committing to the database).
2. Then I have validation errors (which is ok because some fields are mandatory).
3. I search for cars by name.
The funny part is that if I search for cars with given names, I get those cars AND I get the empty row with this new car I'd tried to add just a moment ago. It's definitely not yet in the database and the name of this car is not set (so it shouldn't match with the name I'm searching for).
My question is: why is it happening and what should I do to get the rows created but not yet committed not appear in the search results?
I tried to use clearCache() method of ViewObjectImpl but the result is still the same.
Please help because I desperately need this for my diploma project.
Thanks,
Anna

I run: "java -Djbo.viewlink.consistent=false -jar oc4j.jar" and I still get new rows. I'm using OC4J 10g (9.0.4.0.0) standalone that comes with JDeveloper 10g (9.0.5.2) on Linux.
And about that Create pages: I mean I click on a link "New something" 3 times (for example). I don't use the browser back button because I have my menu on each page. In this case I'm just curious if it's possible to somehow "overwrite" previous "new" rows with the most recent one.
I thought I would need that but now I know I need something else.
Imagine such a situation:
1. A user wants to create a new row or update an existing one.
2. They start filling the form and submit it (in my case it's committing at the same time)
3. During validation it turns out that some required values are missing so the user has to enter them.
4. At this point the user leaves the input form and decides to add or update a different row.
5. The user enters all the required values and this time validation would succeed. However, because of points 2. and 3. it does not.
Now my question is: how can I make ADF somehow "forget" about the row inserted/updated in point 2. I know that ADF validates all new/changed rows at a time. But I would like to change that behavior so that it would validate only the row changed/created most recently.
Thanks,
Anna

Library list question

I just got a new computer, redownloaded iTunes, and imported my music back into it. Somehow I got most, if not all, my songs in my library twice. It is a pain but I can go through and delete them. My question is that some of the songs now have an exclaimation point icon in front of the title of the song. I was unable to find a list of what the icons mean. I am afraid to start deleting the duplicate songs until I know what the exclaimation point means. Anyone know? Sorry if this is already posted out there somewhere. Thanks.

Hello,
The exclamation point icon means that the music file was moved from its original location at some point and is no longer there. So the 'duplicate' ones are the old songs, that have the exclamation points, and can be deleted. However, they are not different files. The songs without exclamation points should be the ones that work (if you click on them they should play.) To be safe, I would check to make sure that the songs without exclamation points work and the ones with them don't work before you delete anything. Hope this helps.
