Transient attribute for a view object coming from a socket

Hello,
I'd like to create a readonly table (based on a view object without a backing entity).
Some columns are coming from a table and some other columns (based on the table key) are coming from a socket.
The problems is that the additional columns are all returned at once by the socket (to avoid calling it for every field and killing our network) and then stored in a java bean.
So i'd like to make the call to the socket once for every row of the table.
Do you know in which method of the View object should i make the call (maybe I should do this at the Row level ?)
Do you have any idea ?
thank you
-regards.

Hi,
you can try the follwing
In the bindings of your jspx page you can see iterators defined under "executables". set the "*CacheResults*" property of the specific view object iterator that contains the transient attribute to false.(The default value is true).
Example:
<iterator Binds="EditWorkflowNodesView1" RangeSize="25"
DataControl="AdministratorAppModuleDataControl"
id="EditWorkflowNodesView1Iterator" CacheResults="false"/>

Priya.

How to make Transient Attribute Mandatory in View Object?

Hi ,
I have a Transient Attribute 'TransientFromCode' which is based on LOV .On UI ,I am showing this 'TransientFromCode' as 'SelectOneChoice' .
So on selection of this i am populating other mandatory attributes.
My requirement is to show this as 'Required' on UI but in View Object i am not able to find mandatory property for this attribute.
I dont want to use required='true' . So can you plesae tell me is there any way to make Transient attibute as mandatory on UI .
Thanks

940637 - Your Use Case is a little vague\confusing.
If you are just trying to get the standard "Required" architecture, it probably isn't working because you have incorrect syntax. It is #{bindings.MyViewObj.MyAttr.hints.mandatory}
Yours: "#{bindings.UnitOfMeasureIntraClassConversion.hints.TransientItemDesc.mandatory}"
It will "dynamically" pick this up at Runtime from the ViewObject Attributes "Mandatory" property (Attributes\Details tab), BUT the EL will always evaluate to "true" so this is the same functionally as just hard coding the UI component's Required property to "true" (although doing so is against Best Practices)
If you are just wanting to SHOW the field as required without the standard Validation logic (because you are coding your own), you could:
1) JUST set the UI component's "ShowRequired" property = true. This displays the * next to the Label (regardless of actual View Object Attr setting) but fires no validation.
2) If you want to not show * but some custom standard, you could just create ANOTHER transient Attribute in the View Object and call it "TransientItemDescRequired" and set it to a Literal "y" or leave it blank and programmatically set it later... You can code your own validator\method\whatever against it, etc

Transient attribute of a view object is not reset after saving

Setting bind variable for a view object from the Managed Bean

Hi,
i am using JDeveloper 11g, i have to create LOV in the JSF. To show the LOV, it has to populate data using View object and its query parameter need to be sent from the Managed Bean.
For the View object i want to set the bind variable parameter from the managed bean value. bename is stored in a managed bean (session scope)
#{beantest.bename}
But it gives the following exception.
JBO-29000: Unexpected exception caught:
org.codehaus.groovy.control.MultipleCompilationErrorsException,msg=startup failed, Script1.groovy: 1: expecting '!',found '{'@ line1, column 2.
I have followed the link http://kr.forums.oracle.com/forums/thread.jspa?threadID=615474 like Frank wrote on 8.2.2008:

Edited by: user9928180 on Dec 17, 2008 9:51 AM

Hi,
a bind variable in a VO needs to be exposed as an executeWithParams operation in the pageDef file. Just add a new action binding to the pageDef file (context menu) and select the executeWithParams operation on teh VO. Then in the argument field, reference the managed bean property for the value

Can a web service be used as the datasource for a View Object?

Has anyone used a web service as the datasource for a View Object?
I am trying to do the same thing as "Publishing BC4J Components as a Web Service" example, except I want to recreate the View Objects on the client so that I can iterate through them and display them on a web page.
I probably have two choices:
1. Use the web service as the datasource.
2. Use a file as the datasource with no data and then populate the View Objects from the XML from the Web Service.
Please advise.
Thank you.
Richard Catlin
SAIC

You can adapt the examples provided in the BC4J Toy Store demo for how to build a programmatically-populated view object to create a view object that fetches its data from a web service.
The methods that you need to override are the same for any kind of programmatically-populated view object.

Bizarre behavior of a View Criteria for a View Object

Hey,
I remarked quite a bizarre behavior of the View criteria that I created for my view object, using bind variables.
lets say I have the generated query in the View object:
SELECT Paquet.ID,
Paquet.WEIGHT,
Paquet.VALUE,
Paquet.ORIGIN,
Paquet.DESTINATION
FROM PAQUET Paquet
I want to use the executeWithParams with bind variables for this View object.
I create a bind variable:p_o
I create the View Criteria vith the visual editor that generates an additional view clause:
( ( ( Paquet.ORIGIN LIKE ('%' || :p_o || '%') ) OR ( :p_o IS NULL ) ) )
test query works and explain plan as well.
Now, when I execute the view object on a page with the bind variable properly set, I get the error: java.sql.SQLException: Attempt to set a parameter name that does not occur in the SQL: p_o
Then I copy the where clause generated by view criteria visual edito directly to the query and delete the View Criteria, and it ALL WORKS FINE
If has to work like that, then what is the View Criteria useful for? I still think that there is a problem.
Thanks!
Taavi

Hi,
ViewCriterias are not accessed with ExecuteWith Params. For this the bind variable needs to be in the where clause. Named ViewCriterias are listed separately in the DC list

Programatically add / Rmove Attributes to a View Object

I have a View Object with 2 attributes created at design time. I need to add more attributes to it at runtime based on some information I get. Is there a way to add/remove Attributes of the View Object programatically at runtime ?
Any help is appreciated.

add following method in your GridViewImpl class
public void setDynamicColumns()
for (int i=0;i<5;i++)
this.addDynamicAttribute("Dynamic" + i);
write this method in your moduleImpl
protected void afterConnect()
super.afterConnect();
this.getYourGridView().setDynamicColumns();
run your app
Hope that helps

View link accessor for master view object with bind variables

Is there a way to set bind variables for a view object to which a view link accessor is used to retrieve a view row from a detail view row in a master-detail relationship ?
I understand that RowSet (or Row) returned by a view link accessor originates from an "internally created" view object instance.
I am using 10.1.3.0.4 JDeveloper.

Thanks! that's right the bind variables when i use it on where clause must be required, so i change my sql to:
Select /*+ use_nl(p p2) */
'F' tipo_persona,
p.ID_PERSONA, p.TDOC, p.NDOC, p.DENO
From SINT_PERSONA p,
( Select /*+ index(a SINT_PERSONA_IX2) */
a.ID_PERSONA
From SINT_PERSONA_DOCUMENTO a
where ( NDOC = :p_cuit
and :p_cuit <> 0 )
) p2
Where p.id_persona = p2.id_persona
AND (deno = decode(:p_deno,'null',null,upper(:p_deno)) or
:p_deno = 'null')
AND (NDOC = decode(:p_ndoc,0,null,:p_ndoc) or
:p_ndoc = 0)
and grado_confiab > 0
and my bind variables:
p_ndoc required default value 0
p_cuit required default value 0
p_deno required default value null
and works ok!
thanks a lot !!!!

How to use SPEL for Dynamic View Objects?

Hi Gurus,
In Benefits Self Service particularly in the Designate Beneficiaries page, we have a requirement to set the row for Self designation as Read Only. What this means for any plan that you're eligible and that requires beneficiary designation, you are not allowed to designate yourself. Unfortunately this is an intended functionality and the only way to achieve our requirement is thru Personalization. I was able to accomplish this successfuly thru the SPEL functionality. However the view object corresponding to each plan that requires beneficiary designation is somewhat dynamic. For example, Plan A corresponds to BeneficiaryPeopleVO1, Plan B corresponds to BeneficiaryPeopleVO2, Plan C corresponds to BeneficiaryPeopleVO3, etc. The Personalization Page only allows me to use the SPEL for only one view object at a time. So if an employee is eligible for 3 plans that require beneficiary designation and my SPEL points to BeneficiaryPeopleVO1, it will only set the Read Only in Plan A. Plan B and Plan C would still allow self designation. Is there a way I could use the SPEL to work for all View Objects?
Thanks,
Ronaldo

The variable name has little importance, but OTOH the object reference has great importance. Instead learn about arrays, Lists, and Maps.

How to set query for child View Object?

I have a hGrid in standard page. Two View Objects are present connected using view link. I need to set where clause in the child View Object. The changes are not getting reflected when i set the where clause. Also when i try to fetch rowCount it returns 0 for child View Object. But i am able to get the value for parent View Object. Any suggestions please.

Hi,
This solution worked for me last time, Please create One blank row and delete that row(For Child VO).
Why we are doing this? : Because the child vo pointer might not init. See this is not our fault, this is because of OA Framework. But this works for me :)
Thanks,

I did try making a VO that extends the original VO, but with the attribute based on the SDO_NN_DISTANCE function call, which means that a call to SDO_NN MUST be in the WHERE clause.
This works to some extent, in that the common attributes and methods are in the second VO, inherited from the first, without me having to write them again. However, I have to use them in my ViewController project as two separate VOs. For one thing, I need two separate result pages, one for when the query used the SDO_NN in the where, and needed the distance in the output, and one without. One uses the original VO, and the other uses the new one. Similarly, I need two separate pages for adding additional criteria. Doing it this way with pairs of nearly identical pages is going to be a pain, and will be difficult to maintain, since any change will have to be done twice. Or can .jspx pages be written that extend other .jspx pages, and in particular override the VO bindings in the pageDef? Could a single .jspx page decide dynamically which pageDef to use?
I decided to try a different tack. Back to a single VO, I wrote a WHERE clause that calls SDO_NN, but returns all of the rows. That way, I can have a call to SDO_NN_DISTANCE in the SELECT for all queries, and I was even able to add a parameter that sets the Distance attribute to NULL if it is irrelevant to the query the user constructs. This is a good work around, but it is a little slow, because SDO_NN is doing a lot of work but returning every row when it hasn't been replaced with an "actual" SDO_NN where clause.
One more possibility: Can I have a method that replaces the entire SELECT command for this VO dynamically? I assume that you need to make sure that the expressions in the SELECTed data still map to the attributes one to one, with the same aliases. After all, I am already replacing the WHERE clause dynamically, and it works fine.
