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,
Shrikant

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

Is something like this possible ?AFAIK, it is only possible in a very limited way as noted above and is nearly always not recommended and definitely not necessary. The variable name has little importance, but OTOH the object reference has great importance. Instead learn about arrays, Lists, and Maps.

How to set updatable property of view object on runtime

Hello Gurus,
I am new in adf and using jdev 11.1.2.3.
I have two view object which has view link and they are based on entity object. In master view i have a column with the name of status. The target is if the value of status is 'active' then i want to allow add rows in detail view and if it is inactive then wants to disable adding or editing in the detail view.
I don't know how to do this. I don't know how to get the other view object and how to set update able property and where to write code in entity object class or view object class.
Any advice................
Thanks in Advance

There are multiple possible ways to archive this. As the VOs are in a master-detail relationship, you can opt to add a navigation method to the child back to the parent. This method can be accessed via java or groovy to allow the child access to the master row. Once the child has access you can use this to ask the master for it's status and if it's not active disable the edit and update buttons.
If both master and detail are on the same page in the ui, there is an easier way. Drag the status attribute from the master table onto the page as e.g. inputText. This will create a binding for the attribute which changes if you select a row in the master table. As you don't need to inputtext, switch to the source mode of the page and delete it. This will remove the inputtext put keep the binding. Now you can use hte binding in an EL to set the disable property of other components to true like
<af:commandButton text="commandButton 1" id="cb1" disabled="#{bindings.masterstatus.inputValue ne 'active'}"/>
The button will only be active it the binding for masterstatus is active.

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.

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

I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?
I will appreciate your help.

HOW TO: set anchoredObjectSettings for .palce() object?

Hi, I'm currently working on interesting script for GREP placing, and I'm wondering how I can set anchoredObjectSettings for .palce() object?
for(i=0; i < found.length; i++)
    foundElem = new File (myFolder + "/" + found[i].contents);
    found[i].place(foundElem); // Placing Ancored Object
    // HERE IS WHERE I NEED SOME HELP: how to set "anchoredObjectSettings" for just placed Ancored Object
    //anchoredObjectSettings.anchoredPosition = AnchorPosition.ABOVE_LINE;
    //anchoredObjectSettings.horizontalAlignment = HorizontalAlignment.TEXT_ALIGN;
Here you can download example files - script, InDesign file and images, that should be placed into InDesign file with script
Dropbox - GREP placing.zip
PS: I believe this script will be very useful, so if anybody have any ideas/suggestions, and want to help me with further development - this would be great!

Hi Kai, this script is still under development, here is updated version attached (now it can also place files/images by file name only, without extension):
#target indesign;
//#include "! Basic functions.jsx"
    GREP place files.
    This script will ask to select source folder with files to place,
    and then, with dialog box (or prompt) [this is not implemented yet, so I use static GREP value while developing]
    will ask to type GREP find expresion to search for text placeholder, that need to be replaced with file from source folder we just selected.
    TODO: Check how it works with other than image formats
        Also, this might be usefull to make anchored frame with column widh, and fit image proportionally

Top part with Windows/Mac filtering was copy-pasted from default InDeign script "ImageCatalog.jsx" as example and modified - I'm not sure if all this stuff is needed, I haven't test if it works the same without those filtering on both OS - if that's not needed - then thanks for tip!
PS: in your findWhat \l{3,4} will not catch .ai files
and what means .source at the end? is that doing necessary escaping, so with it it's posible to write \l instead of \\l

Passing an argument in the SQL Query of a View Object

Hi,
It is possible that this question has been asked before, however I have searched for a half an hour in the forums and couldn't find a solution.
I am also new to using JDeveloper and ADF. Here's the situation:
I am developing an application that doesn't have to do anything else then displaying data from a database. Pretty straightforward actually.
Now I have made a vew pages with several collapsible panels (af:showDetailHeader) and have setup the datasources (or so I thought).
All that remains is:
- drag & drop a view object, from the application module that I created, onto the collabsible panels, so a child element gets created which displays data from the database.
- hack the layout so it looks like I want it to.
The problem that I have is the following:
I am using a 'User'-class that contains values I need when quering the database.
That User-object is part of a user-session.
What I want, for example, is to use the 'getPersonId()' function of that User-object and pass the argument to a SQL-query of a certain view-object.
The query would become something like:
'SELECT * FROM people WHERE people.personId = :someNumber'.
Now I've read some stuff about variable binding, which is complemented by something like (backing bean code):
getDBTransaction().getRootApplicationModule().getACertainViewObject().setWhereClauseParameter(1, user.getPersonId());
The examples I have found that might match my wishes are not using business components, but EJB's. I am having difficulty with understanding the 'how'-part of variable binding.
Also, I do not know enough of ADF to be able to create a situation like:
'User loads page, collapsible panel 1 is fully shown, the others are undisclosed.'
(meaning, that for panel1 a query has been executed.)
'User clicks on collapsible panel 2 which triggers a backingbean that somehow retrieves data from a view object'.
I would appreciate any help that somebody can give.
If it is not too much of a problem, please provide code snippets in case you have a solution. I am new to ADF :(.
-edit
I am using JDeveloper 10.1.3.3.0 in case that is of any importance.

Hello Stijn,
I didn't think about a referenced bean rule in the faces-config.
I added it right away and I am now able to set parameters of a View-object, not using a page button and before the page loads. You made my day!
In case anyone ever reads this post again, the summary of how to generate a table based on a View-object using dynamic parameters.:
1a: Go to faces-config.xml -> Overview tab'
1b: Go to the menuitem "Referenced Beans"
1c: Click on 'new' and select the existing bean you want to access data from and input a name. In this example I use name="user"
2: Create a View-object using the wizard.
2a: Specify the query you want in the menuitem 'SQL Statement'.
Add the 'parameters' you want to. You will have something like:
"SELECT * FROM someTable WHERE table.columnname LIKE :someArgument".
- hint: if you want the result to become something like:
"SELECT * FROM someTable WHERE table.columnname LIKE '%someArgument%'" then you have to add the '%'-characters in your code itself (read: someClass.setParameter("%" + someArgument);).
2b: In the menuitem 'Bind Variables' you have to add the variables you are referring to in the query. If you look at the query in 2a, then you have to add a variable with name "someArgument".
2c: Add the View-object to a Application Module (create one if nessecairy).
3a: Open a .jsp(x) file. Drag the View-object created in step 2 from the 'Data Controls'-pane to the page.
3b: Click on the '+' of the View-object in the 'Data Controls'-pane and open 'Operations' and drag 'ExecuteWithParams' to your page as a button.
3c: We do not want to use a button, the action has to be executed immediatly. So In the page source remove the lines that were created after dropping 'ExecuteWithParams'.
3d: Right-click on the page and select "Go to Page Definition".
3e: Go to the action id that is called 'ExecuteWithParams#', where # is a number.
Change the id to something useful.
3f: Change the NDValue so it corresponds with the value you want.
Example:
<action id="getAddressData" IterBinding="AddressesView1Iterator"
InstanceName="MyHRServiceModuleDataControl.AddressView1"
DataControl="MyHRServiceModuleDataControl" RequiresUpdateModel="true" Action="95">
<NamedData NDName="someArgument" NDType="java.lang.String"
NDValue="#{user.personId}"/>
</action>
Note: It is possible to use the value of a Backing Bean in NDValue.
Note 2: user is the bean I referred to in the faces-config.xml!
3g: Under the executables item, add an 'invokeAction' to pass the parameter to the View-object before your JSP-file loads:
<executables>
<invokeAction Binds="getAddressData"
id="loadAddressDataOfPersonIdInSession"
Refresh="prepareModel"/>
Thank Stijn Haus for this :)

How to construct a new complete view object programmatically

HI,
I want to construct a new complete view object programmatically. I have a result set based on the rows returned from this query i need to build the new vo and show it n a form. Please tell me the complete procedure to do this or else provide me any links.
Thanks
Satya

Hi,
have a look how dynamic tables are created (using af:forEach to iterate the attribute Defs for generating columns). Your approach is similar except that you not only need to know about attributes but also the rows to fecth
1. create a tree binding for the view object
2. create the binding with one hierarchy
3. ensure all attributes are deleted for the tree binding (you do this manually in the PageDef)
4. when executing the query for a new SQL, call clearForRecreate() on the DCIteratorBinding instance
5. On the page, use af:forEach to create the form fields and labels for each row. Like for dynamic tables, you first need to determine the attributes to render (its a nested loop you are going for
6. Updates of the form fields must be through a managed bean

Problem with saving Parent - Child View Objects in ADF 11g.

Hi Every one,
I have a requirment, something like I will be displaying some data on my jsff screen based on one Transient View Object. Whenever user clicks on Save button, I have to do following steps in my AMImpl.
-> Preapre dynamically Parent View Object Rows based on some logic
-> Prepare dynamically Child View object Rows and invoke insertRow method on respective child view object.
When I say commit() First Parent ViewObject data need to be saved and then Child View object data has to be saved. I am having Parent - Child Key relation ship btw these two ViewObjects. Some how I am populating the Parent Primary key in the Child View Object. Please suggest me If there is any other alternative to this.
Thanks

I got the solution, Enabling the check box option for Master - Detail Entity association (CompositionAssociation -> Cascade Update Key Attributes) resolved the issue.
Thanks

View Links for Programmatic View Objects

Hi All,
I created a read only VO called MyVO based on a sql query.
I created 2 programmatic view objects, MasterView and ChildView.
In a custom method in AMImpl class ,I iterate through this MyVO resultset and get the rows in a Row object.
Based on some attributes values of the Row, I populate both master and child View Objects.
I have created a view link between Master and Child Programmatic View Objects and have exposed them in AM.
Now I run the AM, and run the method exposed in client interface.
Now I click on my master and child programmatic views.
I see that the rows are populated in both of these programmatic VOs.
But when I click on viewlink which I have exposed under master, it doesnt show me any
record for child.
This is my method of AMImpl which is exposed in AM client interface.
public void constructLines(){
ViewObject vo= this.getMyVO1();
ViewObject master=this.getTransientVO1();
ViewObject child=this.getTransientLineVO1();
Row r,masterRow,childRow;
int count=0;
while(vo.hasNext()){
++count;
r=vo.next();
masterRow = master.createRow();
if(r.getAttribute("QuoteHeaderId")!=null)
masterRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
if(r.getAttribute("QuoteLineId")!=null)
masterRow.setAttribute("QuoteLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("LineNumber")!=null)
masterRow.setAttribute("LineNumber",
r.getAttribute("LineNumber").toString());
master.insertRow(masterRow);
childRow= child.createRow();
if(r.getAttribute("RefLineId")!=null)
childRow.setAttribute("RefLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("QuoteHeaderId")!=null)
childRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
child.insertRow(childRow);
This is stopping me from my development progress.
Any suggestion to solve this will be of great help.
Thanks,
Prabhanjan

Hi..
have you define relationship correctly between masterVO and childVO.sometime there may be the problem.

Changing the query on a view object

I have a view object right now, based on an entity. It is the default view object, so that means the query in the view object is straight forward, it grabs all of the attributes from the table. And there is no WHERE clause.
In reality I only want to show a finite set of rows from my table. Every time a record is changed/edited in this entity and committed, a new row in the database is created with the same information (I'm using CreateWithParams) except for a few columns.
I actually don't really have update on this table, just creation of new rows. But to the user, I want it to 'look' like they are editing something in the table.
Example:
12, 11:32,Thompson, 60 (the user edits this information in an adf table, and a new row is created in the db)
12, 11:55, Thompson, 75
I have a timestamp (see above) field in the database that is used as part of my primary key, so that I know which record is the latest.
When the VO query is run, I want the user to only see the latest row from the db.
12, 11:55, Thompson, 75
So...
I went to my VO, and I changed the WHERE query to add this:
where t1.TimeStamp = (Select MAX(t2.TimeStamp) FROM rcl.x t2 where t1.uid = t2.uid);
Now, this isn't a mysql/sql question. There's actually a better query that I'd rather run, but the VO editor doesn't allow me to change the query itself....
When I save the new WHERE to my VO, run my page again, I get the expected result (showing me only the latest records).
However, when I try and sort on the table in which my data is displayed, I am now getting ORDER BY errors.
I don't want my VO to be read-only sql based. I want to be able to update my table, so I have my VO running off of the entity.
Why doesn't the VO allow me to change the query itself? (Like do a subquery, instead of having my where clause do the work)
Why are order by errors being thrown when I sort on my adf table after changing the where clause in my view?
Hopefully I wasn't too convoluted in the explanation of my problem..
Thanks in advance,
Joel

HI Joe,
Regarding your problem you can do one of the following tasks:
1- easily to tuning on your view object, I mean in the tuning page of the view you can set that only return 1 record or 2-3 record fetch not all the record.
in the order by you will order by the timestamp field and descending.
2- you can order by the timestamp descending and in the where clause only set the rownum<2 (will return the last record) you can also set rownum<5 and get the 4 last record etc.
3-editing the view query in the expert mode is not advised at all because of many consequences that you will face.
4- maybe it is not bat that you add a readonly view for the table you mentioned and every time you unpdate the entity just re-execute the read-only view.( this method maybe is good maybe is not it depends on your business logic)
Regards.

How to add row in multiple view object based on common entity object.

Hi ,
I have
Jdeveloper version - 10.1.3.3.0
Oracle Database - 11g R2
I have a situation where i have to show data from one table in three adf tables on jsf page depending on a flag value in a column in table. For this purpose i have done the following steps
a) Created an entity object on the database table .
b) Created three view objects on this entity object and edited the view object's SQL and included the where clause
                   WHERE A.USER_PERSONAL_NO = :P_USER_PERSONAL_NO AND
                       A.AUTH_TYPE = 'LF'
                   The auth_type cloumn decided in which view object the data will be shown
Now, when i query the data from database by executing the query of these view objects the data is shown correctly in all three view objects. Till here there seems every thing ok
Now , i have to provide the logic to add records in the adf tables for this i have provided add button in action facet of all three tables which are binded to methods in managed bean,
when i add a record in a adf table by add button the new row which is created is shown in all three tables . I cant understand why this is happening , please help me to solve this problem.
How can i make it possible so that the record appears only in that adf table in which the record is added.
The method for adding record is
            Row rw = currentAM.getWfRecommAuths().createRow();
            rw.setAttribute("UserPersonalNo",this.getQuery_personal_no().getValue());
            rw.setAttribute("AuthPersonalNo","");
            rw.setAttribute("AuthType","LX");
            currentAM.getWfRecommAuths().last();
            currentAM.getWfRecommAuths().insertRow(rw);
           Please help , thanks in advance.

Unable to set Labelfield for child element in List

Hi All,
Below is code I am trying to execute
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml" verticalGap="0" xmlns:local="*" height="500" creationComplete="init()" >
<mx:Script>
<![CDATA[
private var arr:Array = [{ firstName: "Alex", children:{lastName: "Abc"}}]
private function init():void{list.dataProvider=arr;
]]>
</mx:Script>
<mx:List variableRowHeight="true" wordWrap="
true" id="list" labelField="
chidren.lastName" /></mx:Application>
I basically want to access the children.lastName on my List. Please let me know how exactly can I do it.

A: Unable to set Labelfield for child element in List

labelFunction is the best way to do this. The attached code also shows how to do it with an itemRenderer, though that would not be as efficient.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
layout="horizontal"
creationComplete="init()" >
<mx:Script>
    <![CDATA[
      private var arr:Array = [{ firstName: "Alex", children:{lastName: "Abc"}}]
      private function init():void{
        list1.dataProvider=arr;
        list2.dataProvider=arr;
      private function createLabels(item:Object):String{
        return item.children.lastName;
    ]]>
</mx:Script>
<mx:List variableRowHeight="true"
    wordWrap="true" id="list1">
    <mx:itemRenderer>
      <mx:Component>
        <mx:Label text="{data.children.lastName}"/>
      </mx:Component>
    </mx:itemRenderer>
</mx:List>
<mx:List variableRowHeight="true"
    wordWrap="true" id="list2"
    labelFunction="createLabels"/>
</mx:Application>
