Hi
Any one help me please on BC4J View Object Attributes should display in Uppercase only. currently default is InitCap.
much appreciate your help.
Regards
Srini

Hi Frank,
Thanks for the suggestion.
I followed the link.But if a transient attribute is modified,then also ((ApplicationModule)getDataProvider()).getTransaction().isDirty() is returning true and the transaction is made dirty.
I am setting a transient attribute like this getNwOperVOIter().getCurrentRow().setAttribute("AcctNoTrans")....when I am editing a row.
Can I get explicit handle at viewobjectimpl for this transient attribute??
Regards,
Praveen

How to change sql expression of SQL-Calculated Attribute of view object ?

Hi
jdev 11.1.1.5
I have a view object with a SQL-Calculated Attribute (sumAnalytic) how can I change sql expression of this attribute in runtime?
for example in application module method??

Hi Mr Timo
Thanks for your reply but I do not need dynamic vo because I can not change all of my vo
I only need to change expression of SQL-Calculated Attribute of view object in run time.
For this I set expression in view object something like this 'select 2 from dual' and in run time in my AM method I get the vo query and replace 'select 2 from dual' with something like 'selet sum(amnt) over (partition by 1)' and set new query.
But I think the better solution must exist
Thanks

Null Pointer Exception after adding Transient attribute in View Object

Hello Experts
I am using Jdev 11.1.2.3.

Hi,
Just the exception stack without any information like what JDev version, what expression you've used for the default value of the transient attribute etc., is not enough for us to help you.

Deleting attributes in view objects...

I rewrote my query and now the attribute mappings are all wrong. The number of columns doesn't match the number of attributes. Other than laboriously editing the XML for the view object, is there an a way to get rid of all the view attributes and start as if it was a new VO? I tried selecting them in the wizard and structure pane to delete them, but this did not work. The xml file is protected in the XML editor.
Any help is appreciated.
UPDATE:
I figured it out. Never mind.
Message was edited by:
user530348

Best is to Open VO with Wizard . Some times VO can be modify manually using XML files but this method are more error prone.
Hope your VO files got disturbed thats why you can edit with wizard.
If you have its backup copy then open with wizard.
Thanks

Dirty check for transient attributes in view object

Hi,
I am using JDeveloper 11.1.1.4 and ADF BC in my project.
In one of my view objects,I have a transient attribute added for some business logic.
I am doing dirty check in my project as below.
boolean dirty = false;
boolean amDirty = false;
// check application module
ApplicationModule am =
getBindingContainer().getDataControl().getApplicationModule();
amDirty = am.getTransaction().isDirty();
//Check if datacontrol is dirty
BindingContext bctx =
oracle.adf.controller.binding.BindingUtils.getBindingContext();
dirty =
bctx.findDataControlFrame(bctx.getCurrentDataControlFrame()).isTransactionDirty();
return amDirty || dirty;
My requirement is that,I dont want the dirty check to be applied on the transient attribute in the view object.
Is there any way to achieve this.Please advice...

[SOLVED] New attributes in View Object not visible in pageDef

Hi,
I'm having a View Object whererin I create new attributes. The problem is that the newly created attributes are not available for selection in a table binding in the page definition.
It seems like there is still somewhere a reference to the 'old' collection of attributes of the View Object. Is there a way to force an update?
The .xml file of the View seems to have the correct query containing the new attributes. Altough, when I try to edit the table binding in the pageDefinition, the attributes are not available in the 'Available Attributes' frame.
Thanks,

Hi Chetan,
I am now able to add a new tab after adding a new entry with the Main View name in "Assign Access levels to Incident Tabs" in transaction SPRO.
However, I am now facing a new issue when I add a main view in OIF component. There are 12 main views in the Object Instance Schema with ID's MainView<sequencenumber> as shown below.
But when I add a new main view I am getting the ID with the format MainVIew<sequencenumber_hexadecimalvalues> and also I am able to edit the ID value which is not enabled for other main views as shown below.
The problem with this hexadecimal value is that every time a change is done and I save the configuration, the number changes and this is causing problem as the configuration in SPRO does not match and the new tab becomes invisible.
Please could you let me know what could be the reason and how to rectify this?

Transient attribute in View Object

I need to create a transient attribute on a VO query based ,I need a transient attr with a string value ,then I used the JDEV wizard and keep Literal value option and put a value string in value box.
The problem is that when I drag and drop the relative property from DATA CONTROL to create an output text field , running all I don't see on web page the inserted value on VO, why ?
thanks

If you don't need to change this value then you can use Expression instead of Literal and put value under " ".
But, if you need to change this value, then you can:
- add something like this to your query: (select 'default_value' from dual) OR
- override createInstanceFromResultSet() in your ViewObjectImpl class and set default value to row OR
- if value of this transient object can't be null, use modified version of codigoadf approach:
public String getDummy() {
//return (String) getAttributeInternal(DUMMY);
return getAttributeInternal(DUMMY) == null ? "yourValue" : getAttributeInternal(DUMMY);

Sorry Frank i could not figure out what u rtrying to say.
In my case i have ADF table with two predefined coulmns :
1 : a serial number read only column
2 : a separator coumn
I need help to bind the newly created dynamic attribute in the VO with my newly created column in the ADF table which has a input text as child.
My problem is binding the is not working properly as values entered in the Table are not reflected in the VO.
And when i insert a new column in between two columns which has already filled values the data in the rows does not shift coreespondingly..

How to reference the Parent view Object attribute in Child View object

Hi , I have the requirememt to generate Tree like struture to display Salary from joining date to retirement date in yearly form.I have writtent two Pl/SQL function to return parent node and child nodes(based on selected year).
1.First function --> Input paramter (employee id, retirement date , joining date) --> return parent node row with start_date and end_date
2. 2nd function --> input paarmter(employee id, startDate, end_date) --> return child node based on selected parent node i.e. start date and end date
I have created two ADF view object based on two function return
Parent Node --> select * from Table( EUPS.FN_GET_CONTR_SAL_BY_YR(employeeId,retirement Date, dateOf joining)) ;
Child Node --> select * FROM TABLE( EUPS.FN_GET_CONTR_SAL_FOR_YEAR( employeId,startDate, endDate) ) based on selected parent node.
I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?
I will appreciate your help.
Thanks

I have created view link(ContractualSalYearlyByYearViewLink) betweem two view by giving common field empId, stDate , endDate.(below is the view link xml file).
I tried give the binding attribute values using parent object reference like below in com.ContractualSalaryByYearlyView xml file but getting error

Changing the Updatable property of a View Object Attribute through code

Hi,
Is there a way to set the "Updatable" property of an attribute in a view object through code ?
I checked the API docs for the AttributeDef class but there is no method to set this. there is a constant (UPDATEABLE_WHILE_NEW) which gives the current value.
My requirements in short - I have a ADF editable Table. Based on a flag whether it is SET or NOT, i need to make a particular column such that the inputTextBox on this column must appear for only the new rows inserted into the table. For all the existing rows users should not be allowed to edit values on this column.
I know this can be controlled with the UPDATABLE property on the attribute in the view object by setting the value as "WHILE NEW".
Now i need to control this through code at runtime.
Please let me know on ow to do this.
JDev version: 11.1.2.3
Thanks.

the method you are looking for is available in the AttributeDefImpl class which you can get from the EntityImpl like
this.mDefinitionObject.getAttributeDefImpl("YOUR_ATTRIBUTE_NAME").setUpdateableFlag(AttributeDef.UPDATEABLE_WHILE_NEW);

Inserting a new row in a BC4J View Object with an attribute of type BFileDomain

Hi all,
I've to insert a row in a View Object with an attribute of type oracle.jbo.domain.BFileDomain.
I do this within an Application Module's method, which has an input parameter of type byte[]. This parameter will be the content of the BFILE.
What's the right way for doing that?
I've tried with the following code, but I've got an exception in committing the transaction:
public int serializeDocument(int codDomanda, int codSorgente, byte[] content, String est, int type, int cost, String title, String arg) throws JboException {
int code = 0;
//File f;
DocumentiTwoView = getDocumentiTwoView();
java.sql.Statement stmt = ((DBTransaction) getTransaction()).createStatement(1);
try {
Row docRow = DocumentiTwoView.createRow();
SequenceImpl seq = new SequenceImpl("documenti_seq", getDBTransaction());
Integer next = (Integer) seq.getData();
code = next.intValue();
docRow.setAttribute("Coddocumento", new Number(code));
docRow.setAttribute("Titolo", (String) title);
docRow.setAttribute("Argomento", (String) arg);
docRow.setAttribute("Costo", new Number(cost));
docRow.setAttribute("Tipo", new Number(type));
docRow.setAttribute("Coddomanda", new Number(codDomanda));
docRow.setAttribute("Codsorgente", new Number(codSorgente));
//f = new File("Doc" + code + "." + est)
BFILE src_lob = null;
ResultSet rset = null;
rset = stmt.executeQuery ("SELECT BFILENAME('DOC_DIR', 'Doc" + code + "." + est + "') FROM DUAL");
if (rset.next()) {
src_lob = ((OracleResultSet)rset).getBFILE(1);
BFileDomain bfd = new BFileDomain(src_lob);
bfd.setBytes(content);
bfd.saveToDatabase(getTransaction());
docRow.setAttribute("Contenuto", (BFileDomain) bfd);
catch (Exception ex) {
getTransaction().rollback();
throw new oracle.jbo.JboException("Impossibile creare il nuovo documento:\n" + ex.getMessage());
finally {
try {
stmt.close();
catch (Exception nex) {
try {
// Commit the whole transaction
getTransaction().commit();
catch (Exception e) {
e.printStackTrace();
getTransaction().rollback();
throw new JboException("Impossibile eseguire il commit della transazione:\n" + e.getMessage());
return code;
Thanks a lot in advance!

Odd, have you disabled caching and indirection? (NoIdentityMap, dontUseIndirection, or alwaysRefresh/disableCacheHits). If so, then this could be the issue.
Otherwise please include the sample code you use to perform this, and verify that you do not have any unusual code in your set/get methods or in descriptor events. Also turn TopLink logging on and include a sample. Also ensure that you do not modify your objects until after registering them in the unit of work, and only modify the unit of work clones.
