Sort view object rows with transient attributes

Hi ,
Is it possible to sort the results of a view object based on the populated transient attributes ?
Best regards
K

K,
Have you had a look at section 27.5 of the ADF Developer's Guide for Forms/4GL Developers ("Performing In-Memory Sorting and Filtering of Row Sets") - I've not tried it with transient attributes, but it does describe how to do in-memory sorting, as opposed to the normal way of sorting which is to send an ORDER BY to the database.
Hope this helps,
John

How to prevent creation of view object rows when using browser refresh butt

HI i have the following problem:
I have a creation form using a partial submition. The problem is that if i have entered some value by using autosubmit , this value will be setted as attribute in the ViewObject . After that if i click refresh button of the browser then the new Row of the view object will be created and i will have a pending row with setted attribute. So if execute commit then the both rows will be tried to commit. How can i prevent this?
Krasi

Hi,
If i've understood you have a invokeAction that create a new row, right? If yes put on condition that it invokeAction won't invoke if is a postback.
Let me know if i miss understand your doubt.

Can Shuttles be based non-base table ViewObjects with transient attributes

Hello,
Users have to select records from a data collection and a Shuttle looks most appropriate/nice for this purpose. We can introduce technical intersection tables in order to generate the Shuttles with JHeadstart 10g R3 if necessary, but there is no “functional” need to update any data in the database and therefore it would be practical if the ‘right’ side from a Shuttle can be based non-base table ViewObjects with transient attributes only. So, our interested is to know which records have been selected, i.e. moved to the right side from the Shuttle.
Hope that my question is clear enough.
Greetings,
Michael

Michael,
This cannot be generated out-of-the-box.
It is easiest to add the shuttle post-generation to your page, and then create a custom template to generate your custom shuttle into the page. I suggest you take a look at an example of a generated shuttle in a page, and the JHeadstart IntersectionShuttleBean class. You will see that the value property of <af:selectManyShuttle> points to the selectedKeys method in the JHeadstart Shuttle bean. In your case, you can create your own managed bean and bind the value property to your own method which will provide you access to the selected rows. The value property of the selectItem within the af:selectManyShuttle determines the property that is used to identify the selected row (which is the row key in case of Jhs-generated shuttles).

How to reset View Object row state to Unmodified

Hi,
My requirement is as follows. In my home page, I have a table listing master records with links to a master detail page. In this master detail page, the master is displayed in a form, and details in an editable table. There is also a button that is used to "Add 5 New Detail Rows". User will use this button to add multiple new detail records for insertion.
Anyway, when user visits this master detail page, I should also programmatically add 5 new detail rows. For this, I define a custom method in the master view object class (called add5MoreRows()...see below), define the binding to this custom method and add invokeAction executable in the page definition.
public void add5MoreRows() {
DlistHdrVORowImpl row = (DlistHdrVORowImpl) getCurrentRow();
createMoreLineDetailRows(row, 5);
// Need to reset the master row state to Unmodified
public void createMoreLineDetailRows(DlistHdrVORowImpl row, int howMany) {
RowSet detailRowSet = (RowSet) row.getDlistLnVO();
for (int i=0;i<howMany;i++) {
Row detailRow = detailRowSet.createRow();
detailRowSet.insertRow(detailRow);
detailRow.setNewRowState(Row.STATUS_INITIALIZED);
The problem here is when I add these detail records, ADF sets the master record to "dirty". My question is how do we reset the state of the master view object row to "Unmodified".

Frank,
That's my first thought. But I cannot find STATUS_UNMODIFIED in View Object. I understand the status can be set in Entity Object. How do we get ahold of Entity Object from View Object?
Thanks.

View object Rows

Hi,
I am extending an OAF page. In which I am trying to get access to all the rows of a view object. This view object is used in an advance table. The advance table shows me 15 rows. 10 rows at a time(Advance table functionality).
Now when I write this code, it return me 15 as a result.
String.valueOf(vo.getRowCount()But when I try to run this code to iterate to each and every row, it just returns me 10 rows.
AwardLineVOImpl vo = (AwardLineVOImpl)am.findViewObject("AwardLineVO");
AwardLineVORow vorow = (AwardLineVORow)vo.getCurrentRow();
     while(vo.hasNext()){
        vorow = (AwardLineVORow)vo.next();
        oapagecontext.putDialogMessage(new OAException(vorow.getBidNumber()));
     }I want to know how can I get access to all the rows in the view object. As I can see the advance table shows 10 rows at a time. And when you click next, the next 10 rows are shown.
Regards,
B

The "row state" is only meant for entity object rows, not for view object rows.
For further details and a possible solution, please check How to identify inserted/modified row(s) in a VO
(Not related) Mr. "73012", I noticed you posted lots of answers on this forum lately. Nice of you that you want to help, but much too often (IMHO) you are not explicit enough to provide a useful solution. Or, sometimes, not quite attentive to the question...
If you are an Oracle employee, please take a bit more time to read the question; and maybe make your name public... If not, the same ;)
Thanks,

Sort LOV view with transient attribute

Hello,
I am using JDeveloper 12c.
I have a view object with a list of value. Let's say EmployeeView and EmployeeStatusLovView.
I have a transient attribute on my list of values. Let's say statusDescription.
I want to sort my list of value with the transient attribute. How can I do that ?
I saw that I can easy sort with non transient attribute.
If it wasn't a LOV, I could override the executeQuery and call setSortBy(), but with a LOV it doesn't work as the executeQuery isn't called.
Any ideas?
Thanks,
Cindy

Ok I get it. The problem was that I tried to override the executeQuery() instead of executeQueryForCollection(). With LOV the first one is not used. Calling setSortBy("myTransientAttribute") in executeQueryForCollection() works just fine!

Sorting on table with transient attributes

Hello all,
I would like to know if it is possible to enable sorting on a table with only transient attributes? I have an advanced table which is based on a VO that has all transient attributes. In this scenario, is there a way to enable sorting? Is this supported? Please let me know.
Thanks in advance
Raja

Raja,
Here are my responses:
I would like to know if it is possible to enable sorting on a table with only transient attributes? >>Yes
I have an advanced table which is based on a VO that has all transient attributes. In this scenario, is there a way to enable sorting?
It does not depends whether the attributes are transient or not as sorting in framework will be done on view instance, you can still enable sorting in advanced table.For details refer to dev guide.Is this supported?>>Yes

New view object row does not get committed to DB

Hi guys,
on a taskflow with a new transaction I have a form to enter a new record on an entity-based view object.
Before the page is called I call the CreateInsert Operation to create the new record on that view object.
There are quite a few attributes that have default values which I determine in the ViewRowImpl's create method (using populateAttributeAsChanged to set the values).
Now if none of the inputValues in the form is filled manually and I want to save the data (default values are sufficient to save the record) the taskflow return action commit does not commit the data to the db. As soon as I manually enter one value into any field the same return action commits the record correctly to the db. There is no error message and the new record is visible in the application because it is inserted into the view's iterator...
Is there any way to mark the new row as changed/insert if only the default values are filled? Or am I doing something wrong?
Using JDev 11.1.1.5
Achim

Add the following method in your RowImpl class:
public void setNewRowState(byte b) {
     if (b != Row.STATUS_INITIALIZED ||
         getNewRowState() != Row.STATUS_NEW) {
         super.setNewRowState(b);

Problem with transient attribute attach to standard vo from the controller

Hi all,
I attached two transient attributes to the standard vo through controller.
Then i passed values to these fields from controller based on another field in the standard vo.
I created two columns in the table without given the view instance and view attribute.
But in the controller i'm setting the view instance and view attribute for this two columns.
After i applied this extended controller it is working fine, but one problem is there.
Once if i clear the cache and then i enters the page, the extended fields are appearing with null. if i press F5 in the browser then its working fine.
same problem happens only when the cache cleared or server gets bounced. so i need to go each page and press F5 once then everything is fine.
Here, I shared my code, please tell me what is the problem and how to solve this.
Code:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject cvo=(OAViewObject)am.findViewObject("FinalCompListVO");
if(!cvo.isPreparedForExecution()){
cvo.executeQuery();
if(cvo!=null){
try{
String temp1=cvo.findAttributeDef("XXCompNameAttr").toString();
}catch(Exception e){
cvo.addDynamicAttribute("XXCompNameAttr");
try{
String temp1=cvo.findAttributeDef("XXCompTypeAttr").toString();
}catch(Exception e){
cvo.addDynamicAttribute("XXCompTypeAttr");
Row compRow[]=cvo.getAllRowsInRange();
for(int i=0; i<compRow.length;i++){
FinalCompListVORowImpl cVORowImpl=(FinalCompListVORowImpl)compRow;
String name[]=cVORowImpl.getName().split("\\.");
String compName=name[2];
cVORowImpl.setAttribute("XXCompNameAttr",compName);
for(int i=0; i<compRow.length;i++){
FinalCompListVORowImpl cVORowImpl=(FinalCompListVORowImpl)compRow[i];
String name[]=cVORowImpl.getName().split("\\.");
String compName=name[0];
if(i==0){
cVORowImpl.setAttribute("XXCompTypeAttr","Behavioral");
}else if(i!=0&&compName.equals("FUNC")){
cVORowImpl.setAttribute("XXCompTypeAttr","Functional");
break;
OAMessageStyledTextBean mstb=(OAMessageStyledTextBean)webBean.findChildRecursive("XXCompTypeCol");
mstb.setViewUsageName("FinalCompListVO");
mstb.setViewAttributeName("XXCompTypeAttr");
OAMessageStyledTextBean mstb1=(OAMessageStyledTextBean)webBean.findChildRecursive("XXCompNameCol");
mstb1.setViewUsageName("FinalCompListVO");
mstb1.setViewAttributeName("XXCompNameAttr");
Thanks in advance,
SAN

Hi,
1. ExecuteQuery should already be executed in Base Controller, So please check if you need it. though i don't think that might be causing the issue.
cvo.executeQuery();
2. The code where you call findAttributeDef and handle the Exception, Can you debug that portion. As It may not be throwing exception in any case and so the Attributes were never added to VO and Page Displays null..
I am not sure, but i think the issue seems to be around 2.
all the best

App module view object row currency and task flows

Hello -
Using JDev 11gR1. My application uses ADF Rich Faces with ADFBC.
I have case where I want to
a. select a row in a table based on a view object
b. hit a button to invoke a method in an application module.
c. in the app mod method, call getMyViewObject().getCurrentRow() to get the row selected by the user
d. "do something" with the row
In 10.1.3, this worked fine.
In 11gR1, I am having problems:
1. The above situation works fine if I have a regular page.
HOWEVER,
2. The above situation does NOT work if my table is in a page fragment in a task flow. (The getCurrentRow() returns NULL.)
For case #2 I've checked the following:
* verified that the selectedRowKeys and selectionListener attributes were set on the table in the page
* verified that I'm using the correct app module instance (I have nested application modules).
* experimented w/various transaction and data control scope settings in the task flow definition.
So... from those details is there something obvious I am doing wrong? It looks like cases #1 and #2 above use different row set iterators. Is there a way to grab the correct row set from within my app module method? Does this have something to do with the data control scope defined by the task flow? (For 11g do I need to "rethink" sticking logic in the app module and instead placing it within a managed bean get access to my ADFBC objects via the bindings layer?)
Thank you for reading my question,
-- Scott

See this article for View Object tuning tips:
http://www.oracle.com/technology/products/jdev/tips/muench/voperftips/index.html
Are you planning to use this AM as a nested AM inside other application modules?
If you don't the "selection AM" will have its own, separate database connection/transaction.
If you do, it will share connection, transaction with its containing "root" AM.
It may not be relevant to your application, but just realize (which is explained in the article I point to above) that view objects that are not related to entity objects do not "see" pending changes in the current transaction. That feature depends on the VO/EO cooperation. It's fine to build VO's without an EO -- in fact we've made it easier to do this in 10.1.2 in the Design Time wizards -- but you just want to make sure you realize what features it's giving up. If you don't need those EO-related features, then by all means create an Expert Mode VO that's not related to EO's.

OAF, View object used with the clausule setWhereClause, show the error not have been properly initialized.

Hi to all,
I'm new with oaf and in mi AM i have to VO that I use to find relative information to the one is shown to the user on a query region, after the user pressed the go buton the CO request the AM tho load both VO and those information are used to show in a popup region to display and update. the main problem is when the popup region closes it send a submit to the server an the error "View object may not have been properly initialized during Update." is displayed
The main page and the popup uses the same AM, the initM2mVo() and initTavleVo() are called by the CO at the processRequest of the main PG, the popup dosen´t have a CO.
This the AM that uses the main PG and the popup region

thanks to all.

I thing I got the problem.
I have the following configuration:
One Main Page and external RN that is call as popup in main page
2 VO, queries by java code, one to capture some information that is used to query the 2 VO that I use to update information by the popup.
One AM that is map only in the Main Page. (Initially I had the external RN mapped to same AM as the main PG, but I remove it).
The solution was remove the mapping of the AM from the external region and in the messageimput of the external region set the View instance and view Attribute manually in this fields (http://screencast.com/t/uDTALEedCh do not use the wizard ) as the one instanced am the AM, so the problem it seem that was that defining an AM to the external region create a new instance, causing that it can not see the information that I load manually in the VO by query it them.
for this case there is not need to use the next code, because the Rows are load with information by the query in the java code, this only will have to be made when inserting a new row .
    public void initM2mVo(){
        //get a handle to the View Object that we wish to initialize
        OAViewObject vo = (OAViewObject)this.getTascTransEqInstM2mVO1();
        if (!vo.isPreparedForExecution()) {
            vo.setMaxFetchSize(0);
            vo.executeQuery();
        //Create a blank Row
        Row row = vo.createRow();
        //Attach that blank row to the VO. Data will be fed into this row, when the user types into the fields
        vo.insertRow(row);
        //Set the status of the blank row to initialized. This tells OA Framework that record is blank and must not be included in DML
        //Operations until    changes are made to its underlying VO [via screen fields]
        row.setNewRowState(Row.STATUS_INITIALIZED);

Use view object as table in attribute expression of view object

Hi. I have a view object for which I need to add some transient attributes associated to a SQL expression which works good. But when I need to define an attribute expression associated to a view object expression, not table, the framework doesn't recognize it. It is, when I want to use an expression like this:
select attribute from MyViewObject where id=EntityObject.id
I know I can call EntityObject.id but not use the view object MyViewObject as a table. Is it possible? Is there a way to do something like this? Greetings.

Hi Timo. The use case consist of having a VO with static values and there is another VO that references as foregin key the previous VO, something like:
VO1: Statuses of Vendor
VO2: Vendor detail with attributes including the status
In af:table component I want to show vendor info showing the status name and not the id of the status. I thought there was something like hibernate in which I could query the VO as a table. Greetings.

Treetable with transient attributes

Hi,
I use JDeveloper 11.1.1.2.0 to develope an ADF application.
I need to create and show two level treetable using viewobjects theese have only transient fields.
I have two viewobjects and a viewlink described below:
1. VO : AccountsVO
2. VO : ProductsVO
Viewlink : ProductsOfAccountVL
An account can has a lot of products. Both of viewobjects have only transient attributes.
I have to use transient attributes because of the architecture of the application.
I create and insert the rows to the viewobjects in managed bean.
I need to create a treetable like below :
AccountName1 AccountDesc1
---ProductNo1 ProductName1 ProductDesc1
---ProductNo2 ProductName2 ProductDesc2
AccountName2 AccountDesc2
---ProductNo3 ProductName3 ProductDesc3
When I drag and drop the parent VO as an ADF Tree Table then run the application, I could see only first level records.
I mean only Accounts are shown.
The viewlink doesn't work. Is this a bug or is it normally work like this.
Finally I intend to create and add child node programmatically, but I don't know is it possible or not and how could it be done.
What do you advice or what is the correct way.
Mehmet
Thanks.

Hi Frank,
I don't have any entity object, so I get the informations from a few different modules and
insert them to the programmatic viewobjects which have transient attributes.
In fact I could create 2 temporary tables on the database but I am not allowed to change the database schema.
By the way I have updated my JDeveloper from 11.1.1.2 to 11.1.1.3 I will try the same operation and inform you.
Thanks.
Mehmet.

Fetching vo results with transient attributes

Hi, I have a filterable table bound to a view object.
I created a custom multiple select functionality by adding a checkbox to each row. The checkbox correlates to a transient value on the view object. When the checkbox is selected, the transient value is set to true.
I have a "select all" option at the top of my table, and when that is selected, it goes through all of the rows in the view object and updates the transient value to be true, then all of the rows should be selected in the ui.
The range I have set on the iterator is 100 fetched rows at a time, but many times the total in the view object is around 1000.
When the "select all" feature is selected, all 1000 rows are getting their transient value set in my backing bean, but this is not reflected in the UI.
When I scroll down, 100 rows have the checkbox selected, and past that, new rows are fetched, and they aren't appearing to be selected (even though I specifically setting the value to true in the backing bean).
Does anyone have an idea on how I can set and see a transient value for rows that have not yet been fetched?
Thanks,
Joel

Problem extending a VO with transient attributes

I am trying to extend a VO that is based on a query with a Binding Style of Oracle Positional.
The Attributes that are listed for the original VO are the attributes from the Query Statement plus some transient attributes.
I extended the VO by modifying the query. Added my two columns at the END of the Select statement.
Successfully substituted the VO but I am getting a runtime error when saving a record.
Reviewed the extended VO and noticed that the new columns are listed as attributes AFTER the transient attributes.
This could be the cause of the runtime error since one of the transient attributes listed after the query attributes is RowChanged.
How can I force my new attributes to be positioned BEFORE the transient attributes?
Is this the problem or is it something else?
Thanks for any suggestions.

Runtime error:
java.lang.NullPointerException
at oracle.apps.pos.supplier.server.ByrSuppAMImpl.validateDffVo(ByrSuppAMImpl.java:3575)
Yes, I have checked the attributes (Updateable Always, etc.) and the attribute mappings and they all seem fine.
My two new attributes are at the end of the original attributes. I think my new attributes should NOT be at the end of the original attributes because the original VO.xml has attributes from the query and then transient attributes that are not from the query. My extended VO now has the attributes from the original query, the transient attributes, and then my new attributes from the query.
The first two transient attributes are RowChanged and RenderFlex and it seems like OAF is confusing it with my new attributes because:
(1) the runtime error I get when saving (RowChanged attribute)
(2) the Flex field icon grays out after my VO extension was deployed (RenderFlex attribute)
To test out my theory, I would like to move my new attributes to be listed BEFORE the transient attributes.
I tried editing the VO.xml file by moving my new attributes (query-related) to the end of the other query-related attributes and before the transient attributes (that are not query-related). When I try to view my changes inside JDeveloper, the attributes are shown in the new order (on the left) but the query mappings are still listed in the old order.
Where can I re-order the query mappings? Tried using the up/down arrows on the right but it's grayed out.
If I re-order the attributes in the VO.xml file and save it, is that all the change I need to do?
Thanks.
