JBO-27008 in transient attributes

I have in my VO a transient attribute defined with a sub-query.
I had displayed this attribute as a checkbox in my UIX.
When trying to commit changes in the page, I have the JBO-27008 message that this attribute is read-only (or course it is). What have I configured wrong to have this message? My VO attribute is set as Updateable = Never, and Passivate is on...

Idevaldo,
You could set Updateable to Always, and just don't do anything on the set method of your transient attribute.
Kind regards,

ReadOnlyAttrException: JBO-27008 occurs when it shouldn't

Hi,
I am receiving the ReadOnlyAttrException: JBO-27008 error on attributes that are always updateable. The situation occurs in the following circumstances:
* I have a view object that works fine - no errors
* I add a String transient attribute to the VO, with "Always" selected under updateable
* When trying to set the attribute, I get the JBO error mentioned above
In looking at the RowImpl class for my VO, I notice that when I add the transient attribute, it is inserted directly before the last attribute at the top of the class, like so:
protected static final int RENEW_LEVEL_TEXT = 18;
protected static final int USERVIEW = 19;
where RENEW_LEVEL_TEXT is the new transient attribute and USERVIEW was the old attribute that had value 18 before the change. USERVIEW is a view link accessor. The VO I am working on is on the destination end of the link.
Anyway, the method I call is setRENEW_LEVEL_TEXT(), but the error I receive tells me that the USERVIEW is read only, leading me to believe that somehow, internally in a place I cannot find, USERVIEW is still associated with value 18.
any ideas?

I believe you're running into bug
2632675 -- TRANSIENT VO ATTRIBUTE INCORRECTLY BINDS AS NULL IN VIEW LINK
which should be fixed in 9.0.3.3.
Thanks.

Oracle.jbo.ReadOnlyAttrException, msg=JBO-27008 Attribute set fail

Hello,
I keep getting this error saying that my view attribute fails in my view object. The view attribute that is failing is CtType1 which is a transient attribute. Does anyone have any ideas?

Make sure the updateable property of the attribute is set to "Always" even if its a trasient attribute.
Inside the ViewObject in the ADF Wizard, choose your transient attribute and set the Updatable radio buttons to "Always."

Oracle.jbo.ReadOnlyAttrException) JBO-27008: Attribute in view object cannot be set.

Hi all,
I have three table:
Member : MemberID(pk), Email, Adress, ProvinceID (fk)
Province : ProvinceID(pk), ProvinceName, CountryID(fk)
Country : CountryID(pk), CountryName.
After created three entities and object view for all of them.
In ProvinceView : i add a parameter for CountryID using Bind Variables + View Criteria to select Province from Country
In MemberView : i add more two entity: Province and Country then Add more attributes: CountryID (from Province table), CountryName(from Country table).
Create LOVs for CountryID and ProvinceID....that's i want: selected Country ----> Province auto show but when i selected Country, an error show like this :
(oracle.jbo.ReadOnlyAttrException) JBO-27008: Attribute Countryid in view object PhaiMemberacbView1 cannot be set.
What's solutions to fix this. Thanks

Hi,
Please verify if the Attribute Countryid has been marked as "Updatable" in the view object.

Oracle.jbo.ReadOnlyAttrException: JBO-27008

Hello, friends!
I use uix for my application (generated with JHeadstart).
Now I have one problem, and this problem is very strange. Some of VOs throws exception after commit changes:
(oracle.jbo.ReadOnlyAttrException) JBO-27008: for one atribute, which is readonly and i did not try to update it.
at oracle.jbo.AttrValException.<init>(AttrValException.java:112)
at oracle.jbo.ReadOnlyAttrException.<init>(ReadOnlyAttrException.java:40)
at oracle.jbo.server.ViewRowImpl.setAttribute(ViewRowImpl.java:815)
at oracle.jbo.jbotester.JboTesterUtil.setData(JboTesterUtil.java:173)
I don't know why, but all worked fine before.
I think that this is not view project problem. Because the same problem appear on the other pages (oracle.jbo.ReadOnlyAttrException: JBO-27008:)
and when i test model project with bc4j tester now. But sometimes this problem appears on the uix page testing and does not appear when i test this
VO with bc4j tester. For example, one my VO hane primary key: Id, updeteable=always, display=false and when i try to update another
VO in this page i recieve same error. This error appears for attributes which are always updatable and for attributes which
are readonly and when i do not update it.
Maybe you can tell me how to solve this problem, please.
Thank you.

Erik, thank you.
But I have not custom logic in the isAttributeUpdateable() method.
This attribute is transient (java.util.List). And the get attribute method is:
public List getMyList()
{ if (MovesListAdapter!=null)
return MovesListAdapter;
ViewObject vo = this.getApplicationModule().findViewObject("MyVO");
System.out.println(rowSetName);
RowSet rowSet = vo.findRowSet(rowSetName);
if (rowSet==null)
rowSet = vo.createRowSet(rowSetName);
rowSet.setWhereClauseParam(0,this.getIdOsnovanie());
rowSet.executeQuery();
rowSet.setRangeSize(-1);
String rowSetName = "MovesRowSet"+this.getIdOsnovanie();
System.out.println("MovesRowSet row count="+rowSet.getRowCount());
MovesListAdapter = new RowIteratorListAdapter(rowSet, true);
MovesListAdapter.setEmptyRowsAtTop(1);
List t=MovesListAdapter;
return MovesListAdapter;
}

Migration issue on default value for transient attribute in 11.1.2

Experts,
I migrated my JDev 11.1.1.5 project to JDev 11.1.2. After successful migration i began to run the project and it ran without issue. In the application however when i clicked on any link or button i get the following exception

Null Pointer Exception after adding Transient attribute in View Object

Hello Experts
I am using Jdev 11.1.2.3. I have added a transient attribute in view object and set default value to another view object attribute via view accessor of view link between view objects. the value of expression is ItemMasterRO.Description, where ItemMasterRO is the name of view accessor define in the view link and Description is the name of attribute which is in other view object.
Data is retrieving as per my requirements, but when i click on add record button in application module, it is throwing a null pointer exception. Here is stack trace

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.

Creating Transient Attributes when query is in Expert Mode

I wanted to share a recent challenge I encountered. I had created a transient attribute in my View Object and placed it on my .jspx page. When I would navigate to the page I would receive an error telling me, "oracle.jbo.AttributeLoadException: JBO-27022: Failed to load value at index 42 with java object of type java.lang.String due to java.sql.SQLException.".
After switching my run configuration to include the java option -Djbo.debugoutput = console, I noticed my sql statement was getting modified. I inspected the view object sql and realized the calculation for my transient object was not present. After adding the calculation for the column in my sql, I was able to run the page with no errors.
My problem was that I had my query in expert mode so I could utilize an outer join. When I added the transient attribute after putting the query in expert mode, JDEV would not automatically make the changes to my SQL.
It would really help if JDEV threw an alert to the user letting them know that their query is in expert mode and changes cannot be made to the SQL or it would also help if I remembered what I read in the Dev Guide. Such as when a file is read only.
(JDEV 10.1.3.4)

When I added the transient attribute after putting the query in expert mode, JDEV would not automatically make the changes to my SQL.Really depends on what you meant by ' transient '.
Did you really want a 'calculated' attribute - i.e. one that is backed by a query clause - for this you needed to check the 'mapped to column or sql' in the attribute properties and also provide an SQL expression..
Otherwise, it's just a java 'transient' attribute and doesn't have to be part of the query...

Strange error oracle.jbo.ReadOnlyAttrException: JBO-27008:

Hello, friends!
I use uix for my application (generated with JHeadstart).
Now I have one problem, and this problem is very strange. One of VOs throws exception after commit changes. First time it was error
(oracle.jbo.ReadOnlyAttrException) JBO-27008: for atribute mgrList
at oracle.jbo.AttrValException.<init>(AttrValException.java:112)
at oracle.jbo.ReadOnlyAttrException.<init>(ReadOnlyAttrException.java:40)
at oracle.jbo.server.ViewRowImpl.setAttribute(ViewRowImpl.java:815)
at oracle.jbo.jbotester.JboTesterUtil.setData(JboTesterUtil.java:173)
Then I setted updateable property of MgrList attribute to always and now i have this error:
oracle.jbo.domain.DataCreationException: JBO-25009: Cannot create an object of type:java.util.List with value:[{}]
I don't know why, but all worked fine yestarday.
I think that this is not view project problem. Because the same problem appear on the other pages (oracle.jbo.ReadOnlyAttrException: JBO-27008:) and when i test model project with bc4j tester today. But all this pages and data model worked correctly before and i did not edit this.
And this problem look like the bug. Because this error must appear for attributes which are always updatable and when i do not update it.
Maybe you can tell me how to solve this problem, please.
Thank you.

We havent written any custom code in the extended EO.
Case 1 : Without any extension (basic oracle behaviour)
When the Page is first Rendered, the Org Name (LOV) Field is populated on the screen,and OrgId (form value) is also populated with it.
(this is a create screen and Org is populated with the Default Org name and ID)
Case 2 : With we have Extended EO
(we havent generated the EOImpl of extended EO so we cannot possible write any custom code to insert/ update any of the attrubutes.
This Case gives an error as mentiond in my previous mails.

Passivate Transient Attributes

I have a transient attribute in a View Object that reflects the results of a costly calculation. Passivate to PS_TXN seems to me the best way to keep the result from one request to another.
1. Has the calculated value to be cached by setAttributeInternal in the view row internal buffer, or has it to be cached as a member of the view row impl ?
Passivation calls the getter, so it makes no difference. But how are members of view row objects cleared in the case they are "recycled" ?
2. It seems to me that activating a transient attribute is somewhat buggy: the getter is always called before the restored value appears in the mInner-mCalcs member of a view row, which calculates the value unnecessarily. If the value was not cached with setAttributeInternal, it never appears in mCals.

If your transient attributes are updateable, but you use them only within the scope of a single request (e.g. you set the value within a particular request and use it only until the end of this request but not later), then you do not have to passivate them. However, if they are updateable and you need their values to survive across multiple requests, then you must ensure that these attributes are passivated. In order to configure them to passivate you should do the following:
1. Check the checkbox "Passivate State (e.g. Current Row, Bind Variables, etc.)" in the section "General/Tunning" in VO's definition dialog box;
2. Either check the checkbox "Including All Transient Values" in the same section or leave it unchecked but check the checkbox "Passivate" in the definition of the corresponding VO attributes.
N.B. The setting "Include All Transient Values" affects not only the transient VO attributes but the SQL-derived VO attributes (that are not entity-based) too.
The configuration parameter "jbo.txn.disconnect_level" has nothing to do with passivation/activation. The correct way to test if your VOs behave correctly under passivation/activation is to disable AM pooling (e.g. to uncheck the checkbox "Enable Application Module Pooling" in the corresponding AM Configuration dialog box). When AM Pooling is disabled ADF passivates the corresponding AM state at the end of each HTTP request and activates it at the beginning of next request and so on. In this way you can check if your VOs are passivation/activation-safe.

Sorting transient attributes

Does anyone know how to take advantage of adf/uix built in sorting for view objects that contain only transient fields? For example, when I build a view object that references an entity object, sorting (via a uix table tag) works great. However, when using a view object with only transient attributes, sorting does not work through a uix table. Any ideas would really be appreciated...

FYI,
I've figured this out for anyone that sees this post in the future. Here's how to do it.
1 Open the transient view object in the view object editor (by double-clicking on the view object).
2 Select Java.
3 Press the Class extends button.
4 For Object, browse to the following class: SortableTransientViewObject (see below for implementation)
5 Press OK.
6 Select Attributes.
7 For each attributes:
1. Select the "Selected in Query" property.
2. Copy the exact name of the attribute to the query column alias field.
8 Press OK.

Validation error :JBO-27008 vanishes by pressing submit two times???

Hi All
I am developing a web application using ADF BC,struts and jsp with JDEV 10.1.3.
In my JSP page whenever I create a new record, after submit the desired record is submitted into the read-only table below, but I receive the validation error:
JBO-27008: Attribute set for MaterialName in view object viewJoinPurchaseComplexUnit1 failed.
Wondering that when I press the submit button again the error vanishes and my data is inserted into the database.
I'm wondering why I have to press submit two times and then everything goes right? What is wrong among here? what should I do?

Frank,
The view in my BC Tester runs very well. Consider I have a viewJoin which is created by joining 4 view objects and I try to insert in one of them and the other views are reference,updateable. in my jsp page(input form) I have to fill in some reference fields in order to display the user what he has selected from the other page(handeled with javascript). Does this have something to do with the problem? when I do not fill the MaterialName field I do not encounter this problem. I have other fields like MaterialName filled from outside and are reference but they are working fine. Also, I do not have this error when Update, delete, Find/execute, and by create when I change the field materialname to null everything goes fine, but all the other transactions(Update, delete, Find/execute) cripple by that.

Transient attribute in viewobject and entity object

i added a transient attribute to an entity object . Then, for the view object based on that entity object, i added this transient attribute. The attribute name is Department Description. When i display the record(s) from this view object, everything is cool. But, when i try to create/insert a new record, i get error:
JBO-27019: Get method for attribute "DepartmentDescription" could not be resolved. What is going on here and what do i need to change to create/insert a new entity row which has a transient attribute?
As well as i added trasient attribute in view object also ....same erroe is comming ..................
Thanks inadvance

Hello Siva,
have you already solved your problem?
I have a very similar error.
Thanks.

Passivate option in VO transient attributes & AM connection type

Hi
My English isn't very good.
I use Jdeveloper 11.1.1.3.0
I have 2 questions:
1. I defined some View Obj and in each View Obj I made transient attributes. I don't know if the Passivate option of these transient attributes should be enable or not?
2. for AM connection type I use JDBC DataSource : "jdbc/ConnectionName". If I change JDBC DataSource to "java:comp/env/jdbc/ConnectionName", does it exist any difference?

If your transient attributes are updateable, but you use them only within the scope of a single request (e.g. you set the value within a particular request and use it only until the end of this request but not later), then you do not have to passivate them. However, if they are updateable and you need their values to survive across multiple requests, then you must ensure that these attributes are passivated. In order to configure them to passivate you should do the following:
1. Check the checkbox "Passivate State (e.g. Current Row, Bind Variables, etc.)" in the section "General/Tunning" in VO's definition dialog box;
2. Either check the checkbox "Including All Transient Values" in the same section or leave it unchecked but check the checkbox "Passivate" in the definition of the corresponding VO attributes.
N.B. The setting "Include All Transient Values" affects not only the transient VO attributes but the SQL-derived VO attributes (that are not entity-based) too.
The configuration parameter "jbo.txn.disconnect_level" has nothing to do with passivation/activation. The correct way to test if your VOs behave correctly under passivation/activation is to disable AM pooling (e.g. to uncheck the checkbox "Enable Application Module Pooling" in the corresponding AM Configuration dialog box). When AM Pooling is disabled ADF passivates the corresponding AM state at the end of each HTTP request and activates it at the beginning of next request and so on. In this way you can check if your VOs are passivation/activation-safe.

How to reference a custom property in a vo transient attribute expr + bug

Hi all
I have created a transient attribute with an expression that evaluate null content to replace it by a appropriate text.
<ViewAttribute
 Name="DescriptionUI"
 IsUpdateable="false"
 IsSelected="false"
 IsPersistent="false"
 PrecisionRule="true"
 Type="java.lang.String"
 ColumnType="VARCHAR2"
 AliasName="VIEW_ATTR"
 SQLType="VARCHAR">
 <TransientExpression><![CDATA[((Description == null) ? 'Pas de description' : Description)]]></TransientExpression>
</ViewAttribute>I have defined a custom property for that attribute that contains the message text. I was surprised to see that the custom property was not associate with the attribute in the source file. Don't understand where the association is done
 <Properties>
 <CustomProperties>
 <Property
 Name="flex.tree.noLabel"
 ResId="flex.noDescription"/>
 </CustomProperties>
 </Properties>I had some difficulties to use the custom property editor. When creating a new related one by using an existing resource the property column value is not changed and the content 'Property' is generated. Because no relationships exists between attribute and the property, the entry is lost in the table referring custom property list for the attribute when your come back into the view object or if you save an another entry in an another attribute.
So my first question ? Is the attribute editing part the right part to define custom property pairs if they are not related to attributes ? is it a bug ?
My second question is : is it possible to evaluate the bundle in the expression (replacing the literal 'Pas de description' by an expression) ? What is the expression to use ? Where it is described to do such things in the help or in the documentation ?
Thank you

This is wrong
((Label == null) ? {FlexParameterModelBundle['flex.tree.noLabel']} : Label)
What is the correct syntax to refer to the project model standard bundle in the groovy expression ?
Thank for the help !
