Assoc and view links in Jdeveloper

Hi! I created two tables in DB with relationship 1 to 1. Then I created two EO in my app, but assoc and view links don't generated automaticaly. Where might be a problem?
Best regards, Debuger!

I created two tables in DB with relationship 1 to 1What does this mean? Did you create foreign keys between the two tables?

[SOLVED] Multiple Dynamic View Objects and View Links - ADF Tree Table

Hi all,
I've got a method that creates 3 dynamic viewobjects using this:
            ViewDefImpl Level1ViewDef = new ViewDefImpl("Level1View");
            Level1ViewDef.addViewAttribute("LevelDescription","LEVEL1_DESCRIPTION",String.class);
            Level1ViewDef.addViewAttribute("SetOfBooksId","SET_OF_BOOKS_ID",Number.class);
            Level1ViewDef.addViewAttribute("CodeCombinationId","CODE_COMBINATION_ID",Number.class);
            Level1ViewDef.addViewAttribute("Level1","LEVEL1",String.class);

            ViewObject vo1 = createViewObject("Level1View",Level1ViewDef);I can create the view objects fine and create a single viewlink between two of them, however i'm getting problems with 2 view links.
This is how I'm creating a view link:

                                                    new AttributeDef[]{
                                                      vo1.findAttributeDef("Level1")
                                                    vo2,
                                                    new AttributeDef[]{
                                                      vo2.findAttributeDef("Level1")
                                                    "LEVEL1 = :Bind_Level1");

                                                    "Level3View",
                                                    vo2,

                                                    "LEVEL2 = :Bind_Level2");I can get the data to display on an adf tree table if i'm only using a single view link, but when i try and implement 2 view link (for 3 levels on the adf tree table) i'm getting problems displaying the data.
I'm getting the following error:

ADF BC: both ID and view link object as getter/setter in row impl

I notice something when generating the row implementation of VO that have links to other VO. I can't seem to find the logic behind it...
Following model:
users( id, address_id,name,firstname,...)
address(id, street,number,...)
their is an assosiation between the UsersEO and the addressEO. Their is also a view link between the UsersVO and the AddressVO based upon the assosiation of the EO's.
When we create the row implementation of the UsersVO we find a getter and setter for both the address_id as well as the address row object.
Why is this?
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object.
THis does not seem to make sense. How do you use it correctly? Do you just need to set the address_id and can leave the row object null or do they both need to have the same? What if you set the address_id to 1 but the id in the address row object is set to 5...
How do the databindings handle these things?
To me it seems more logical that the VO only has a getter and setter for the address object and handles the address_id in the background according to the values in the address object.
Can someone explain me why this is implemented this way and how to handle it correctly?

Why is this? The definition of the VL allows you to optionally generate accessors for the underliying VOs, i.e. getAddressVO() in the UsersVO and getUsersVO() in the addressVO.
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object. You should add the addressVO to the AM using the VL instead and not by itself.

As mentioned above, once you add the addressVO to AM using the VL, the framework will take care setting the value of the row objects accordingly.

Problem with af:table and view links

I want to display a table with data from a database table called PERSON, so I'm using af:table tag.
The PERSON table has the next fields:
PERSON_CODE
PERSON_NAME
PERSON_COD_STATE
The field PERSON_STATE is a foreign key to other table called PERSON_STATE:
PERSON_COD_STATE
DESCRIPTION
I've created a view to get data from PERSON table (personView). Because I want to show the person state description in the af:table , I've created another view to get data from PERSON_STATE table (personStateView). And I've also created a view link between personView and personStateView.
In the column of the af:table that represents the person state I drop the field 'description' of the state view linked to the person view.
When I run the JSP the state is not shown properly. All the persons are shown with the same state.
When testing directly with the application module, the view link works properly.
Does view links work inside a af:table?
I'm working with ADF 10g.
Thanks

Thanks for your reply.
The second alternative works, but I would be interested in the first one (using a view link).
The foreign key is defined properly:
PERSON.PERSON_CODE is a primary key.
PERSON.PERSON_COD_STATE is a foreign key.
PERSON_STATE.PERSON_COD_STATE is a primary key.
I have created a view link based on that foreign key.
When usign af:table to show the records of PERSON table, all the data of PersonView is properly shown. But the STATE of the person is not ok. It seems as the view link is not working.
Why?
Thanks

Need a how to on a special case for views and view links

I have a typical many-to-many relationship model I'm working on.
Basically, it looks like this:
User 1 -------------< * UserGroupXref *>--------------- 1 Groups
You see this in authentication modules all the time. A user can belong to multiple groups and group can contain multiple users.
My task is to use Business Components to create a form that manages user accounts. This form will consist of a User View (master) and 2 detail views.
The first detail view is a list of groups already assigned to the user. I've already defined a viewlink for this first group and it displays its many-to-many results ok.
The second detail view is a list of groups that are available to be assigned to the user. I was thinking that this detail view should be the product of a MINUS operation driven by a BIND VARIABLE. Being a query based view, I think its query would look something like this:
select group_id, group_short_name, group_long_name
from groups
minus
select xref.group_id group_id , group_short_name, group_long_name
from usergroupxref xref, groups
where xref.user_id = :bind_uid
and groups.group_id = xref.group_id
This introduces a bind variable which raises two questions:
1) Is there a better approach
2) How do you use a friggin bind variable?
Seriously, I noticed that the designer will not let you define a relationship based on a bind variable, which leads me to conclude that you have to pass the value at runtime from whatever client app you're using (SWING, JSF, etc). I really haven't found an example of using bind variables that suites me! Maybe someone can point me in the right direction ...?
Finally I have to add control buttons :
Add Group
Add All
Remove All
Remove Group
Naturally these buttons control the inserts and deletes from the xref table. Does this introduce another updateable view into the app or is it something that the framework somehow handles via the defined associations and what not?
I don't expect anyone to design the form for me, but maybe you can help me at least finish up these view links.
Thanks much!

ADF Navigation List and View Links . any tutorial for this subject ?

Hi
Its two day that i am looking in oracle web site and tutorials that are provided in oracled ADF books.
but i can not figure it out how i can user a Navigation List , view Link to insert record in a child table.
so far i just could create a page that when i change the Navigation List selected item and then refresh that page , the related Fields of child table filled with master table PK.
although i cheched and i saw that ComboBox (Navigation List) auto submit is true.
does any one has a clue about this ?
Thanks

Timo,
Thanks for your reply but there is lot of headache, human errors in removing such VO and associations.
Jobinesh,
I am doing exactly what is described in here http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html
Expected Behaviour:
1. Create Following Association and VL, which is working fine.
PeopleCompanyFkAssoc1 and PeopleCompanyFkAsoc1Link >> 0..1 to * Cardinality Between Company.CompanyID and People.CompanyID
2. Do NOT Create any other non sense Association and VL, but it is creating
PeopleCompanyFkAssoc and PeopleCompanyFkLink >> 0..1 to * Cardinality Between People.PeopleID and People.CompanyID

How fast is findByKey and View Links

Hello,
I'm developing an application in which I'll have two very populated View Objects (one with ~1000 and other with ~13000). My code will pick up one row in the first view object and it will search the related rows in the second view object.
I have some questions about this operation:
1. Should I implement it by calling findByKey in the second View Object or View Links between them?
2. How fast is findBykey? O(n) or something better? And about the View Link, does it execute a SQL query or does it solve by comparison between Java objects?
Thanks,
Eduardo

This reply from the community seems to say yes:
Ethernet = 1 Gbps
Wireless G, Wireless N (2.4 GHz) = 130 Mbps
Wireless N (5 GHz) = 300 Mbps
Wireless "g" is 54 Mbps, not 130 Mbps
This article from Gizmodo seems to say no:
http://gizmodo.com/5921456/apple-airport-express-2012-lightning-review-probably- the-best-router-ever
The article never even mentioned what type of download speed or plan was used, so the numbers are meaningless.
The AirPort Express has a 100 Mbps Ethernet WAN port, which would connect to a modem. Your download speed will depend on the Internet service plan that you have with your provider.
If you really do have a 100 Mbps download plan with your provider, you could probably expect about 85 Mbps because some speed is always lost in the routing process.
What is the speed of your plan with your ISP?

[ADF-11.1.2] Non Sense Associations and View Links while using Mysql as DB

Hello,
I recently started using Oracle ADF with MySQL at design time.
I am following instruction from http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html
With Jdeveloper, I created following tables with Mysql Database connection:
1. Company : (CompanyID, Name)
2. People : (PeopleID, FirstName, LastName, CompanyID [referencing CompanyID from Company Table])
Problem 1 : Everytime when I click OK button to create a "new Table" in mysql database, Jdeveloper throws error "Table Doesn't not exists". and when I refresh database connection, it shows me the new table. I don't understand why Jdeveloper is throwing error !
Once the table and linking between them is done, I can see 1-to-many relation between COmpany and People table on Database diagram ...
In Model Layer, I go for "Business Components from Tables" from 'New Gallery' where in I select both tables from mysql database to create EO & VOs of respective Table.
At the end, along of EOs and VOs, it also create following two associations and VL:
1. PeopleCompanyFkAssoc and PeopleCompanyFkLink >> 0..1 to * Cardinality Between People.PeopleID and People.CompanyID
2. PeopleCompanyFkAssoc1 and PeopleCompanyFkAsoc1Link >> 0..1 to * Cardinality Between Company.CompanyID and People.CompanyID
Problem 2 : 1st Association and VL doesn't make any sense at all !!! If Jdeveloper recongnize relationship correctly between tables on Database diagram and why can't it recongnize correct relationship while creating associations ? This problem is occuring for every table I create in Mysql database.
Also, http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html indicates following:
"+ADF BC does not automatically find the primary keys on your MySQL tables. That has two side effects. You'll see some errors when creating and modifying BC objects, and you'll have to define your BC primary keys manually. However, these errors should not affect your project.+"
But when my EO was created, it was already having Primary Key selected for correct attributes.
Anyways, please help in resolving Problem 2 ...

Error with view link and ADF table Tree

Hello
( Note: View objects are created based on static data but not from database tables)
I created two view objects "SuiteViewObject" and "FamilyViewObject" which are based on static data( stored in collection) but not on database entity. A veiw link "SuiteFamilyViewLink" is created from the above two view objects. An ADFTreeTable is created from the above view objects and view link. When run the jspx page containing ADFTreeTable, following error is occured in the browser.
JBO-30003: The application pool (staticviewobjects.staticappLocal) failed to checkout an application module due to the following exception:

Any help on the above error message.?

Hello
The above error is coming becuase view link's SQL query expects tables. But in my case I dont have tables, view objects are created from static data source(collection).
How to create a view link from view objects which are created based on static data source(collection)?

View Links and Associations

hi all,
What is the difference between view links which is based on associations and view links which is not based on associations?
yours,
Bassam

Hi,
associations is what you can use on the EO to resolve a relation between two EntityObjects. You can e.g use this in code to access parent or detail information.
ViewLinks provide you the same on the ViewObject layer. You can base a ViewLink on an association in which case you don't need to know about what actually the relation is build upon.

How to rename a View Link in a data model?

In JDeveloper 9.0.3, I create a simple BC4J project with a master and a detail. The business components are properly created.
When I try to design the data model for the module, I am able to link the view for the master and the view for the detail, there is no problem to rename the view objects that I select in my data model, but I found no way to rename the view links used between the view objects.
I always get an automatically generated name, like "FkForeignDetailLink1". This is what I see in the data model, and also in the structure of the module, in the "View Link Members" section.
I am able to modify the properties of this view link, but not its name. Am I missing something?
TIA

to clarify... In the AM wizard, you are trying to rename the instances of view objects and view links?
If so, you are right, there is no way to rename view links on that panel. We are working on a better way to do that for the next release. The only way I know of to rename the view links is to shut jdev down and edit the XML for the application modele. This can be dangerous if you get it wrong, so make a backup before attempting this. The hint with renaming things OUTSIDE JDeveloper, I already know, but I don't like much.
As for the AM wizard, I just noticed that I cannot do it inside. But that's no problem for me, as lots of details cannot be done inside the wizard, but there is a way to customize them afterwards. My real problem is that didn't find ANY way of doing it.
A question for you if I may. Why are you renaming the view link instances? I though most users would use the detail view instance directly. The detail view instance would in turn look up the appropriate view link into, what ever its name was. The only place where I saw the bad view link names displayed in JDev was the Structure pane of the AM, under View Link Members. But there is no way to modify them there. As for the detail view instance, I didn't find a place to get to the view link at design time (in 9.0.3.988).
Could you be more precise, please?
Thanks again,
Adrian

View Link

Hi,
I have created a view link in JDeveloper that will create a link between a standard Oracle view object and a view object that has been extended. Could anyone please share the steps on how to get the standard Oracle view object and the custom view object to recognize the view link?
Thanks in advance!

Any ideas??

[ADF-11.1.2] Dynamic EO/VO/Association/View Link/pagedef/JSPX XML Def files

I though I found gold but it has nothing when I clicked on it.
Steve Muench's "Not Yet Documented Examples" [http://blogs.oracle.com/smuenchadf/resource/examples] > "Using ViewObject writeXML and JSTL XML Tag Library" suppose to provide the example. but I am getting File not found error. Seems the sample application doesn't exists any more.
Please point me to correct example for my following use case:
At Run-time:
1. My Application will ask user for database table name.
2. for provided database table name, my application should Generate XML Definition file for EO, Associations, VO and View Links inside Model Project (basically all definition file should be created which gets created when developer create these Business Components for database table through JDeveloper Studio).
3. Once done, application should also generate JSPX file using ADF page template in ViewController Project, with binding definition to it's corresponding newly generated VO Objects from step 2.
4. The page will be then, visible to user to use it (create/update/delete records)
First of all, is it possible to achieve above requirement ? Based on description of Steve Muench's "Using ViewObject writeXML and JSTL XML Tag Library", I think it is possible, but I don't have the sample application to refer.
I could have used dynamic view object concept to display the records with basic page layout. But I want users the ability to modify the create/records/delete the records with following requirements:
1. If require, Business Logic Developer can use Jdeveloper Studio to access new generated Business Components and modify it (like adding some validation rules)
2. If require, UI Developer can access newly generated JSPX file and change the layout.
Please let me know how much and how can I achieve it ?

Shay,
Thank you for your reply. I will take a look at your links.
Use Case:
Application will have different BC for different IT Assets (like Monitor, Keyboard, Servers etc), which will basically hold records for all available Assets (like Display Resolution, screen size etc for all monitor in Monitor BC).
I want to give user; the ability to create, for e.g., the sub-class of Monitor to store more specific attribute-values in different table (which will be linked Parent BC). For e.g.: They may want to care about holding CRT and LCD Monitor records in separate new database table -- Application will ask user what all attributes/Columns they want to see for LCD which is specific to this type AND which is not present in already existing out-of-box Monitor BC/Table - e.g. - "Viewing Angle" Attribute).
With that said, I can write code to create database table on fly (having 1-to-1 foreign key reference to parent table) but writing ADF part seems difficult. I also wanted application to automatically generate new page for newly added VO BC. E.g.: LCD-Monitor.JSPX inheriting all attributes from monitor (parent VO) in the same structure as Monitor.JSPX file is having with extra LCD-specific Attributes in separate panel tab (which again UI developers can customized it).
Too much to expect huh !
I am going to start building the application so If not above way, any other suggestion to achieve the requirement ?
