ADF BC: ViewObject Behavior

Hi all,
Within my AM, there are getters like:
ViewObjectImpl getSomeVo() ...
My question is does this method return a new instance or an existing reference?
If it is an existing reference, will the index of the row iterator index be exactly where it was used (lets say a previous call iterated the index to a certain position) or reset to starting point?
Thanks,
Z

Please see Chapter "28 Application Module State Management" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html for more information on this.
The current row in an iterator is one of the pieces of information that is maintained as part of state management.

[ADF-swing] ViewObject blocks EDT, how to work around?

I'm working with JDeveloper 11.1.1.5.
I have a query-based VO that takes a long time to execute.
While the Statement runs I want to show a Waiting Dialog showing an animated GIF so that the user knows the application is working and not hung.
When I do the query directly then my WaitingDialog shows the Animation as expected. The following runs in a thread of ist own:
ViewObject viewObject = myApplicationModule.findViewObject("MyViewObjectsName");
PreparedStatement s = ((DBTransaction)_am.getTransaction()).createPreparedStatement(viewObject.getQuery(),0);
try{
s.executeQuery();
}(catch SQLException ex){
ex.printStacktrace();
when I Change this to execute the vo instead the Dialog hangs:
ViewObject viewObject = myApplicationModule.findViewObject("MyViewObjectsName");
viewObject.executeQuery();
how do I configure ADF so that it does not block EDT?
bye

An alternative method for the UI is to use the radio buttons control. You can customize the standard one to use the square buttons, and I believe this would give you the equivalent effect that you're doing with the lights. See attached VI along with customized control. For the customized control I took a standard radio button control, opened it for editing, and replaced the circular booleans with square buttons. The radio button control is an enumeration, with the enumeration items being the labels of the individual controls (not the text inside the buttons). The control is set so that the labels on the individual square buttons is not visible.

JDeveloper 11.1.2.3, ADF Faces: aberrant behavior declarative components

Strange things have been happening with my research into declarative components.
1. declarative component cannot be used the within the same project it is defined. only in a separate project which consumes it as an adflib
2. periodically, in the componentdef property inspector for my declarative component would miss displaying all values I defined for "Facet Definitions, Method Signature, Methods". Closer inspection of the code reveals that somehow, the afc tags disappeared! so the code for something like a method attribute would look like:
<method-attribute>
<attribute-name>
commit
</attribute-name>
<method-signature>
void method(javax.faces.event.ActionEvent)
</method-signature>
</method-attribute>
...instead of:
<afc:method-attribute>
<afc:attribute-name>
commit
</afc:attribute-name>
<afc:method-signature>
void method(javax.faces.event.ActionEvent)
</afc:method-signature>
</afc:method-attribute>
...3. during design time, the ActionListener attribute of a button (in the declarative component definition) shows up under "warning node" and states "Reference comp.nameofactionlistener" not found.
Code will run but there are many warnings similar to this.
anyone else on 11.1.2.3 have similar issues working with declarative components? i'm trying to find steps to reproduce but havent stumbled upon it yet.

Wes,
1) is documented at http://docs.oracle.com/cd/E35521_01/web.111230/e16181/af_reuse.htm#autoId21
2) and 3) I personally have not stumbled upon, but if you have a reproducible test case you should open an SR or make an entry in the ADFEMF issue tracker (http://java.net/jira/browse/ADFEMG side is currently down :()

ADF dynamic ViewObject based on query. how to get attributes?

hi.
i have an read-only view object based on query like this:
SELECT :func(:paramm) as EMP_SAL from dual
and set :func & :paramm parameter by vo.setNamedWhereClauseParam(..) function.
but i couldn`t get EMP_SAL attribute after executeQuery command.
in another case i would set new whole Query by vo.setQuery(..) but the problem exists.
please help me. how to get attribute in such vo objects!
thanks!
Morena!

thanks to Quick reply!
i seek into code and found a uninitialized Parameter in view object. error has gone after correct the problem!
and now could get the attribute value.
thanks so much!

ADF : Generating Viewobject table at run time based on Bind Parameter

Hi,
My JDeveloper Version 11.1.1.5,
I am facing one issue. I an not understanding how to deal with it. Its kind of road block for me.
Scenario:
I have a list of value(SOC), Which contains names of projects. Upon selecting one project and clicking on search button, table should be generated dynamically based on a query. To this query I need to pass the selected value from SOC, and should generate the query out put on to the screen, upon clicking on search button.
Could any one please tell me the solution how to implement it?
Please help.
Thanks in Advance,

Hi,
the approach should be
1. on click of search buton get the selected value in managed bean.
2. write a method in am impl to execute the view by setting the where clause with selected value from SOC. the method should accept SOC selected value as parameter.
3. expose the method in clent interface.
4. on click search button method, invoke the am impl method using peration binding.

Viewobject transcient attribute update value base on other field

Dear All,
I have a viewobject with a transcient attribute which is calculated based on some other attributes queried from the DB. I have set the default value of the transcient field using the express:
adf.object.viewObject.getFTType()
and the getFTType() in the viewObjectImpl will return a string base on other fields' values;
Then I test it in the AM Model tester and it looks fine. However, when I drag this VO to a Table in the page, the transcient field column always showing the same value on every rows instead of showing different values base on the other fields on each row.
I've added a button to print the selected row values in the table and after I click on the button, the transcient field column is updated according to my selected row other fields' values and it updates the value for the whole column instead of only the selected row.
I wonder if there is sth wrong I did? Thanks a lot.
The getFTType() method is pasted here:
public String getFTType() {
Row row = this.getCurrentRow();
String ftType = "";
try {
if (row.getAttribute("TxType").toString().equals("99")) { // all non-GJs
if (row.getAttribute("InputFutureTrfDate") != null) { // Future type FT
if (row.getAttribute("TiMToMYorn") != null) {
if (!row.getAttribute("TiMToMYorn").toString().toLowerCase().equals("y")) {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT (Future)";
} else {
ftType = "Misc FT (Future)";
} else {
ftType = "Misc FT M to M (Future)";
} else {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT (Future)";
} else {
ftType = "Misc FT (Future)";
} else { // non-future FT
if (row.getAttribute("TiMToMYorn") != null) {
if (!row.getAttribute("TiMToMYorn").toString().toLowerCase().equals("y")) {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT";
} else {
ftType = "Misc FT";
} else {
ftType = "Misc FT M to M";
} else {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT";
} else {
ftType = "Misc FT";
if (row.getAttribute("TxType").toString().equals("11")) {
ftType = "GJ Interest Income";
if (row.getAttribute("TxType").toString().equals("12")) {
ftType = "GJ Bank Charge";
if (row.getAttribute("TxType").toString().equals("13")) {
ftType = "GJ Others";
} catch (Exception e){
e.printStackTrace();
return ftType;
}

Did you set recalculate on the field you are basing its value on.

How to Auto Select some RadioButton on page load using ADF/JSF

Hi,
I am learning ADF and need some help. I have multiple radio buttons and couple of text boxes on my page. How can I make some radio button be selected based on some value from a database table and also populate the text boxes with the corrosponding value when a page loads. Any tips on how it can be done using ADF. Any sample tutorial will be helpful.
Thanks

Hi,
when you e.g. use ADF BC then the radio button should be selected automatically based on the value of the attribute. If the row is new then you can have a default value specified in the ADF BC ViewObject attribute.
However, if you just dragged the radio button and checkboxes onto the page - not using any ADF binding - then you will have to create a managed bean with a field variable (incl. setter/getter methods) to link the radio button's value property to it using Expression Language

Building tree using view crateria in view objects

suppose that i have the following tables "class" ,"group" and "item".
items in table "item" belong to groups in table "group" and groups belong to classes in table "class" .
suppose there is another table called "selling_basket" that contains an id for the customer and also a foreign key for rows in item table for the items he sold and a "Customer" table that contains customers id and other informations.
suppose that i want to build an JSF page that contains a table from a view based on the "customer" table and a tree of herarichy - class
|_group1
|_item1
|_item2
-class2
|_group2
|_item3
|_group3
and when i click on a row on table customer the tree only display the herarichy for items that this customer sold just.

i solve the probel the description as follow :
. the problem : the problem is that when we use the tree model component with the scenario of filtration on the child nodes, we do a normal transactions of steps on the knowledge that the tree will use the master detail behavior as in table component and other ADF Master-details behaviors, so we build two view criteria one on employee and the other on department with the scenario of displaying only the department who has employees with salary equal some certain value, and only shows the employees who has salary equal that value, and on our code we apply the two criteria on the two view objects with the same value we entered to search for , the scenario works well for the top level nodes, but for child nodes it seems it doesn’t work, the behavior make us walk around our selves for why this happened. By debugging options and Tracing what SQL statements that it executes we found that the system execute two statements on the employee view object one with the bind value with the same we inserted and the other with null value, and we notice that the name of the second view object executed is not what we apply the view criteria for(departmentEO_employeeEO_emo_dept_FK_employeeView).
.The solution: we notice that the tree component doesn’t use master detail behavior as in tables, and instead of that it uses the View link assessors (the run time generated view object departmentEO_employeeEO_emo_dept_FK_employeeView ), to get the detailed items, so we should override the action of the View link assessor.
To deal with that we generate the view object rowimpl and viewimpl java classes, in the rowimpl class there is a method to call the link assessors with the following code:
public RowIterator getEmployeesView()
this.getAttributeInternal(EMPLOYEESVIEW);
We write our code:
public RowIterator getEmployeesView()
System.out.println("Here");
ViewObject s=((DepartmentsViewImpl)this.getViewObject()).getViewLinks()[0].getDestination();//we get the employee object by using the view link
// between department and employee
// then we apply the view criteria to that view object and return it as view link
System.out.println("row number "+s.getEstimatedRowCount());
ViewCriteria evc=s.getViewCriteriaManager().getViewCriteria("EmployeesViewCriteria");
s.ensureVariableManager().setVariableValue("nSal",((DepartmentsViewImpl)this.getViewObject()).getnSal());
s.applyViewCriteria(evc);
s.executeQuery();
return s;
Notice that we use the employee view object getted by the view link instead of the master details.

How can to get connection at runtime?

I use Jdev 11.1.1.4 adf JSF.
I have 2 connection into Model.jpx.
First I use in production and second I use in test.
I would like to change the value of the variable name nowDate, in "Bean Variables" in Query into "View Object".
Specifically, I'd like to change the value of nowDate either adf.currentDate, when I have choose first connection or *12/01/2010* when I have choose second connection.
It's possible?
I don't know how retrive the database connection used to create business components from existing database object by code and i don't know how to write the code in "Expression Editor" into "Bind Variable" of "View Object".
Thank's a lot for any help.

hi user2964099

Thanx Jeanne,
You brought me on a idea with the UIX Developer's Guide and EXPANDABLE_EXPANDED value.
I couldn't figure out how the expand property was filled, because it wasn't done in the ADF BC ViewObject. We have a Utility class that creates a DataObject from the ViewObject Data and here the expand property was set.
Now it was easy to build a ExpandAll option. It is possible to access the HttpServletRequest object were the DataObject is created. By setting a attribute in the request I could react on that and give the expand property indeed the value EXPANDABLE_EXPANDED.

One Bind Variable used in multiple VOs jdev 11.1.2.3 redhat 5.8

Hello:
I have multiple View Objects and each view object needs to use a bind variable. I would like each VO to reference the same bind variable.
Example: I have 3 VO and in each VO where clause I need something like emp_key = :p_emp_key, but I want only one bind variable used in each VO. Is this possible?
So I would like to create one drop down list of values for all the employee names and have all the view objects reference the selected value key of the drop down for employees.
Each VO should reference the same employee selected.
What is the best way to accomplish this?
Thanks much.

Also, you can try the programatic way if it suits your requirement:
1. for all 3 VO, make them extend a base class
2. have a common property with relevant getter and setters in the base class - eg. private String myjob
3. set this varaible from the view(page/screen - button click/dropdown selection etc) using EL
4. in each VO using groovy to access the set variables like this -> adf.object.viewObject.myjob
5. call execute query on requried vo

JBO-25014: Another user has changed the row with primary key...

Hello,
could you help me please with resolving this error "JBO-25014: Another user has changed the row with primary key..." - I am just getting a row from a view by bind "filter" variable, then I am assigning new values for some of the attributes - and trying to commit ..unsuccessfully..
View is based on Entity.
I saw directive for setting Entity's attributes as "update after insert / update" - but this did not help me.
Thanks in advance.

Hi
Please try this solutions:
One solution is to change the ADF BC locking behavior to optimistic instead of pessimistic. Choose the AM and click the Configuration context menu option. Select the LocalAM entry and go to the Properties. Scroll down to the locking setting and change the existing entry
If there is a trigger changing values, you need to mark those attributes (the ones that may be changed) as refresh after insert and/or refresh after update in your Entity Object.
