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

ThanksHi,
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.

ShashidharHi Frank,
Thanks for reply!!
My case is:
I have a Query based ViewObject.
One of the field is LOV and remaining fields are in ADF table. the LOV field is out side ADF table when i insert first record in ADF table and i choose LOV filed the value is selected.
when i create second row LOV value got refreshed because both are in same VO.
I need to get the LOV value of first row and set same value to second Row.

How to populate bind variable in view objects where clause in ADF faces
I've got a page with 2 input items.
The user manually enters the first value.
On the second input item I have created a LOV for the item which opens in a popup. How do I restrict the data returned in the LOV using the value entered in the first input item. I have created a bind variable and have included it in the where clause for the view object but how do I populated it.Here is an example:
Using the HR schema with the EMPLOYEES and DEPARTMENTS tables.
Example is using ADF BC and created an EMPLOYEES entity with an updateable view object for page,
and created a DEPARTMENTS view as a lookup
(SQL: select department_id, department_name from departments where department_name = :DeptName)
1: add method to the backing bean to filter the LOV
public void getTextValueToFilterLOV(ValueChangeEvent valueChangeEvent) {
Object value_from_form = valueChangeEvent.getNewValue();
FacesContext fctx = FacesContext.getCurrentInstance();
Application fapp = fctx.getApplication();
JUFormBinding formBinding = (JUFormBinding)fapp.createValueBinding("#{bindings}").getValue(fctx);
DCIteratorBinding dcBinding = (DCIteratorBinding)formBinding.get("DeptLOVIterator");
ViewObject vo = dcBinding.getViewObject();
vo.setNamedWhereClauseParam("DeptName",value_from_form);
vo.executeQuery();
2. add valueChangeListener to the inputText on the page with an id and autoSubmit="true"
<af:inputText value="#{bindings.LastName.inputValue}" label="#{bindings.LastName.label}" binding="#{backing_DeptForm.inputText3}"
id="inputText3"
autoSubmit="true"
valueChangeListener="#{backing_DeptForm.getTextValueToFilterLOV}">
</af:inputText>
3. reference the LOV with the id name on the partialTriggers property
<af:selectOneChoice value="#{bindings.EmployeesUpdView1DepartmentId.inputValue}"
label="#{bindings.EmployeesUpdView1DepartmentId.label}" binding="#{backing_DeptForm.selectOneChoice1}"
id="selectOneChoice1"
partialTriggers="inputText3">
<f:selectItems value="#{bindings.EmployeesUpdView1DepartmentId.items}"
binding="#{backing_DeptForm.selectItems1}"
id="selectItems1"/>
</af:selectOneChoice>
Summary:
When you entered a text (LastName), that value is passed into the backing bean method.
The Bean method code will find the LOV Iterator and put the value into the bind variable.
Cheers,

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...
Regards,
PraveenHi 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,

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 ?
thanksIf 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);

How to save transient attributes?
Hi,
I have a query related to saving the View Object transient attributes :-
Following is the scenario which we want to implement:-
1. We have a page on which we are using a table component with 5-6 VO transient attributes and n number of rows.
2. There is a save button on the page which allows user to save the activity which he is performing and able to resume the activity later on.
3. As soon as he click on the save button, all the EO attributes get persisted.
4. When he re-opens a flows, he can see a resume button which allows him to resume the activity from the point he left.
5. So User should be able to see the changed he made on the table component on clicking the resume button which he made before saving the activity.
Now, the question is how we can retrieve the transient attributes on resuming the activity or is there any way by which we can save the transient attributes of View object ?
Please help !!Refer

Transient Attributes in Entity object vs View Object
Hi Everyone,
I need some suggestion with my project. I have a vendors table based on which I created an entity object (columns: vendor_id, contract_id, so on ) but I want to display vendor_name in UI which can be read from other table. I thought of using a transient attribute to populate this vendor_name.
It is working fine when I create a new record (where I handled this in LOV return value of vendor_id field and it return vendor_id, vendor_name values) but when there is edit/view of page, this vendor_name is null which means I need to populate it during page load /refresh time. Can someone suggest me a better way to populate this transient attributes. I also want to know when should I use transient attributes in Entity object (I saw most of the developer using VO transient attributes in these kind of situation)
Thanks,
RaviHi,
also want to know when should I use transient attributes in Entity object (I saw most of the developer using VO transient attributes in these kind of situation)
transient values in entities are saved in the entity cache and thus can be changed in the UI. If you use transient attributes on the VO then these are read-only. All transient attribute however need to be populated upon page load, which you can do in a ViewRowImpl class that checks for a null value when the getter is called to then call a setter, or by using Groovy script as a default value (just set the attribute to script)

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

Filter and Sort Transient Attribute from Query Panel
Jdev 11.1.1.3
Hello,
i am not able to filter a transient attribute from the standard query panel (with result table).
I did following things:
-Call an Initial AppMod Service Method from my Bounded Task Flow, and fill the Transient Attribute with some values (with setter method)
-Next, call the Page with following characteristics:
I defined a custom View Criteria with particular Bind Variables, take as query execution mode = In Memory and activate the Auto Query Flag
Drag and Droped this Criteria from Conroll Panel on the Page as Query Panel with Table
In Page Data Binding Definition, i set the InitialQueryOverridden Flag to true, otherwise no data will be filled in the transient attribute
The sort and filter works only for the Database Attributes.
Has anyone an Idea, how to keep same behavior for the trans attr.?
Thank You!
(Note: When i set the Query Mode (after init Call) to vo.setQueryMode(ViewObject.QUERY_MODE_SCAN_VIEW_ROWS), then the sorting of Trans Attr is working fine.
But the filtering is not working well: Lets say a filtering is done by the Trans Attribute and we get 3 Rows. But when all rows wanted to be retrieved again, only those 3 are available then, no chance to get all rows back)Hi,
assuming that sorting and filtering are similar, have a look here

Web ChannelHi,
You can get it from "User" or "Shop" business object.
Try to get User or Shop Business Object as shown below.
BusinessObjectManager bom = (BusinessObjectManager) userSessionData.getBOM(BusinessObjectManager.ISACORE_BOM);
User user = bom.getUser();
char decimalNotation = user.getDecimalPointFormat().getGroupingSeparator();
If you are seeing "1,234.00" then above code will return "."
I hope this information help you to resolve your issue.
