Returning attribute values from Workflow to a Form

Hi,
I have a workflow action that returns an object. I would like to pass this object a form, via a manual action, and get the values for the object. My form has a base context of variables.user. I have attempted to get the object from the workflow by using the :, semi colon however this isn't working.
Any help will be appreciated.
CK

Solved this by using a rule to call the required methods on the object and set the user.xxxx attribute accordingly.
It's easy when you know how!

Returning multiple values from a called tabular form(performance issue)

I hope someone can help with this.
I have a form that calls another form to display a multiple column tabular list of values(needs to allow for user sorting so could not use a LOV).
The user selects one or more records from the list by using check boxes. In order to detect the records selected I loop through the block looking for boxes checked off and return those records to the calling form via a PL/SQL table.
The form displaying the tabular list loads quickly(about 5000 records in the base table). However when I select one or more values from the table and return back to the calling form, it takes a while(about 3-4 minutes) to return to the called form with the selected values.
I guess it is going through the block(all 5000 records) looking for boxes checked off and that is what is causing the noticeable pause.
Is this normal given the data volumes I have or are there any other perhaps better techniques or tricks I could use to improve performance. I am using Forms6i.
Sorry for being so long-winded and thanks in advance for any help.

Try writing to your PL/SQL table when the user selects (or remove when deselect) by usuing a when-checkbox-changed trigger. This will eliminate the need for you top loop through a block with 5000 records and should improve your performance.
I am not aware of any performance issues with PL/SQL tables in forms, but if you still have slow performance try using a shared record-group instead. I have used these in the past for exactly the same thing and had no performance problems.
Hope this helps,

Re: Help needed in passing values from workflow to Approve Forms

Dear Experts,
how do I pass values from a workflow to a step (Form) - approve form?
I am using a customized table structure as my data source (FORMCONTAINERELEMENT) but am stuck on how to access the data when i get to to the screen painter's flow logic... What am i missing? Can you give me a step by step example. the ones i see on the net are input fields that update the screen... nothing that shows value being passed from the outside.
I need to pass an exisitng value in the workflow into the form for approval of the the assigned agent.
Please help!!
Thank you.

Hello !
         Create a method just before the form step.This method should populate the values for the fields maintained in the form.
         Pass the values populated from this method to your customized table structure (data source).In other words, you have to pass all the values to the workflow container.
        To the step, pass this workflow container by binding.In the control tab of form step, you have to do the binding.

[UIX] How To: Return multiple values from a LOV

Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="${bindings.DepartmentId.path}"
    destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="DepartmentId"
    destination="departmentsLov.uix"
    partialRenderMode="multiple"
    partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
    id=DepartmentName
    model="${bindings.DepartmentName}"
    columns="10"
    disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
    <compound>
        <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
        <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
    </compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
    <compound>
        <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
        <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
    </compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.

Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards

How to get attribute value from standard page ?

Hi,
How to get attribute value from standard page ?
String str = (String)vo.getCurrentRow().getAttrbute("RunId");
But this value is returning a null value ....
Can anyone help me to get this attribute value which is actually having a actual value .

getCurrentRow() would always return null if no setCurrentRow() is used.
Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
vo.reset();
vo.next();

How to get attribute value from an object inside an object in Xpress

Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
<ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
<ObjectRef type='Resource' name='Google Apps'/>
</ResourceInfo>
I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
<invoke name='getResourceName'>
<ref>myResInfo</ref>
</invoke>

How can I access the Attribute Values from the Search Region

Hi all,
I have a table which contains Company id, department id, and PositonId. For a particular Company and Department there may be multiple records.
I have to pupulate a table which contains the position and other details that comes under a particular Department and Position based on the selection in the Three comboBoxes.
Also I have to populate a select many Shuttle to add new postions and records under a particular Department.
I created a query panel *(Search Region)* for the serch and a table to display the data. That is working fine.
Now the issue is I am using a view criteria to populate the shuttle with two bind variables ie, DepartmentId and CompanyId.
If the serach will return a resuktant set in the table it will also pupulate the correct records, otherwise ie, if the if the serch result is empty the corresponding iterator and the attribute is setting as null.
SO I want to access the attribute values from the Search Region itsef to populate the shuttle.
I don't know how can I access the data from the Search Region.
Please Help.
Regards,
Ranjith

you could access the parameters entered in search region by the user as follows:
You can get handle to the value entered by the user using queryListener method in af:query.
You can intercept the values entered as described
public void onQueryList(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
List<Criterion> searchList = qdes.getConjunctionCriterion().getCriterionList();
for ( Criterion c : searchList) {
if (c instanceof AttributeCriterion ) {
AttributeCriterion a = (AttributeCriterion) c;
a.getValues();
for ( Object o : a.getValues()){
System.out.println(o.toString());
//call default Query Event
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
public void onQueryTable(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
private void invokeQueryEventMethodExpression(String expression, QueryEvent queryEvent){
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
ExpressionFactory efactory = fctx.getApplication().getExpressionFactory();
MethodExpression me = efactory.createMethodExpression(elctx,expression, Object.class, new Class[]{QueryEvent.class});
me.invoke(elctx, new Object[]{queryEvent});

Getting the attribute value from a table from page def using el expression.

Hi,
Am using Jdeveloper 11.1.2.0.0 and have a requirement as follows for which a sample is been created. Requirement is as follows..
1. Have a Taskflow that has a readonly table Employee.
2. On clicking of a button called "route" checks if the selected row , Manager id attribute value = 200 then navigate to first page else if manager id attribute value is 200 then navigate to second page.
Through the page def , if it has form , then we can access the attributes like #{data.view_FirstPageDef.ManagerId} . In case of acquiring the same attribute value from table using page def ? is what am unable to get..
Have achieved the routing concept using the Router activity on Taskflow. But am unable to get the selected row attribute value of a table from the employee page def.. Can someone suggest on the same...
Thanks and Regards,
Vinitha G

On the router, right click its icon in the task flow and create a page definition. Then in the page def file, add an iterator based on the same View Object from the table in the first page, then add a value attribute mapped to managerId in the View Object iterator. Finally in the router you can write EL expressions along the lines of #{bindings.ManagerId.inputValue = 200} or #{bindings.ManagerId.inputValue != 200}.

Returning a value from a LOV to the main document

Hi,
I'm using jheadsrart with uix, I have a form with a LOV. When I chose a value in the LOV, I need to return another value from that LOV to a hidden field in my main document.
How can I do that?
Thanks for your help!
Martin

Hi Rohit,
Just declare the two variables var1(variable for checking data) & var2(variable for counter) in your include program.
Inside the include you can do the coding as under:
IF VAR1 <condition for checking data>.
VAR2 = VAR2 + 1.
ENDIF.
Now you can check the value of the variable VAR2 in the main program & call the desired function.

Chetan.

How to Return a value to a 10g Oracle Form form a Web Service Call

I've read the demo available from Oracle, 'Calling a Web service from Oracle Forms', that shows how to invoke a call to a Web Service from a Form. The demo only shows how to do a call and how to display messages. I've done some searching, but can't seem to find any examples of how to return a value from the call into a field on the form. If any one could provide an example of that, I would greatly appreciate it.
We are in the process of modifing a form and we would like to use a webservice, which we have never done before. We have created a webservice which calculates a value based upon what is entered on the form and we want to pass that calculated value back to a field on the form.
This is the code provided by the demo to do a call.
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(100);
ex ora_java.jobject;
BEGIN
JO := SendServiceSoapClient.new;
RV := SendServiceSoapClient.sendMessage(JO,:BLOCK3.PHONE_NUMBER, :BLOCK3.MESSAGE_BODY, xo, xo);
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;

In the future, please be sure to include the exact product versions you are using. In this case, also be sure to include the java versions you are using to build your java code.

Return multiple values from a method

For a school project I have to make a parameter-less constructor that can input values from the keyboard and calculate those values. Now that I have the values how do I return them? I need to return 3 values from this parameter-less method.
I hoope someone can help.

Qwertyfshag wrote:
Here is the wording of the assignment. I have copied and pasted it word for word:
"Declare and use a no-argument (or "parameter-less") constructor to input the data needed, and to do the calculations."
Any advice???Find a teacher who isn't an idiot. That sentence is vague ("to input the data needed"? Does that mean that it's supposed to query the user (which is terrible) or that it's supposed to encapsulate the data as hardcoded values, or what?) and is a bad design. Constructors shouldn't do this sort of thing.
Ok I have done that part and now I want to retrieve the values of the calculations. How can I get those values out of that method What do you mean "that method"? Constructors aren't methods, and they don't return values.
I suppose you could define a class whose constructor queries the user, and which would have a method to return values. That could be pretty simple; the method signature would be like this:
Set<Integer> getValues();
This seems like an advanced problem.It's not advanced; it's just garbage.
I can't post the code in hear because that may constitute cheating. I am allowed to discuss it verbally but I cannot share code, sorry.You can't get a lot of help then. We can't psychically see what you've done so far.
In conclusion: I have to have two methods. One method is a constructorConstructors aren't methods. If your teacher told you that they are, then he/she doesn't know what he/she is doing.
that has NO parameters that will get input from the keyboard (done) and do the calculations (done). The other method must print that values to the screen on separate lines (not done). I don't know how to get the values out of the method.If they're two methods in the same class, then the constructor just needs to store the user input into a field of the class, and the other method can read the values in that field.

How do I return two values from a stored procedure into an "Execute SQL Task" within SQL Server 2008 R2

Hi,
How do I return two values from a
stored procedure into an "Execute SQL Task" please? Each of these two values need to be populated into an SSIS variable for later processing, e.g. StartDate and EndDate.
Thinking about stored procedure output parameters for example. Is there anything special I need to bear in mind to ensure that the SSIS variables are populated with the updated stored procedure output parameter values?
Something like ?
CREATE PROCEDURE [etl].[ConvertPeriodToStartAndEndDate]
@intPeriod INT,
@strPeriod_Length NVARCHAR(1),
@dtStart NVARCHAR(8) OUTPUT,
@dtEnd NVARCHAR(8) OUTPUT
AS
then within the SSIS component; -
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Below execute statement should work along the parameter mapping which you have provided. Also try specifying the parameter size property as default.
Exec [etl].[ConvertPeriodToStartAndEndDate] ?,?,? output, ? output
Add a script task to check ssis variables values using,
Msgbox(Dts.Variables("User::strExtractStartDate").Value)
Do not forget to add the property "readOnlyVariables" as strExtractStartDate variable to check for only one variable.

Returning several values from a C native method

Hi,
I need to return 3 values from a native methode : an int (the return code), a string of variable length and a double.
In pure C, my function would be defined as "int f ( char* s, double* d)", and I would "malloc" the string into the calling function, then copy my string to "s" and use "*d" to return the double...
Is there a way to do that with JNI? I found some examples where the native function returns only one parameterlike: "return(*env)->NewStringUTF(env, buffer);" But I didn't find examples where the native function returns several parameters, including a string.
Thanks in advance!
JM

This really has nothing to do with JNI.
You have a method, and you want to return more than one type of value.
The following solutions are possible.
1. Return an array that contains all the values (actual return value.)
2. Return an object that contains all the values (actual return value.)
3. Use an array via the parameter list and fill in a value.
4. Use an object via the parameter list and fill in the values.

How to get attribute values from one view to another

HI all,
Thx in Advance..
I have 2 view like v1,v2.In v1 i used one attribute values from "get single attribute" method.And i need the same values in v2 screen.For this i did in v1 outbound plugs , i mentioned the parameter name . How can i get the same values in v2.

Hi chandru ,
you said you declare the parameters in the Outbound Plug of V1. now go to view V2 inbound plug Tab and creat one inbound plug
double click on the plug name .it will navigate you to the event handeler method . Now add the outbound parameter variables in the
parameters
For example : V1firing the navigation plug
a type string " defined in parameter
wd_this->fire_out_to_view2_plg(
    a =      'ABCD'                           " string
you can retrive the value freely in v2 inbound event handeler
a type string " defined in parameter
*   set single attribute
    lo_el_context->set_attribute(
      name = `TEXT`
      value = a )." here you will get the 'ABCD'.

How to return multiple values from dialog popup

hi all
I'm using ADF 10g. I have a requirement that I have to return multiple values from a dialog.
I have a page containing a table with a button which calls the dialog. The dialog contains a multi-select table where i want to select multiple records and add them to the table in the calling page.
In the backing bean of the calling page, I have the returnListener method.
I am thinking that I have to store the selected rows from dialog in an array and return that array to the returnListener...but I don't know how to go about it with the code.
Can someone help me out with it?
thanks

Hi Frank,
I'm trying to implement your suggestion but getting comfused.
AdfFacesContext.getCurrentInstance().returnFromDialog(null, hashMap) is called in ActionListener method, from what I understood.
ReturnListener method already calls it, so no need to call explicitly.
Okay here's what i'm doing.
command button launches the dialog on the calling page.
In the dialog page, there is a button "select", which when i click, closes the dialog and returns to calling page. I put a af:returnActionListener on this button, which logically should have a corresponding ReturnListener() in the calling page backing bean.
Now I have 3 questions:
1. do i have to use ActionListener or ReturnListener?
2. where do I create the hashMap? Is it in the backing bean of the dialog or in the one of calling page?
3. how do I retrieve the keys n values from hashmap?
please help! thanks
