Populate Programmatic View Objet at runtime

Hi All,
I have a requirement to switch between three different data source at runtime in one page. The UI and field names are the same for those three cases but data is coming from different sources (queries).
So, imagine that we have 3 view objects that implemented as read only (query based view object) and we want to populate one view object at runtime as a main data source for my page.
My idea is to use "Prgorammatic View Object" for that main data source and then dynamically populate its content from one of the three read-only view objects based on a parameter provided by user selection.
First of all, I want to know whether this is fine approach and if so, then get some points about implementation or any other sample.
I have found this sample:
http://techiecook.wordpress.com/2011/05/17/programmatically-populate-view-objects-in-oracle-adf/
Thanks in advance,
Nasser

Hi,
this more is a use case for adaptive bindings. See:https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf
You can use EL to change the ViewObject name an iterator in ADF queries its data from. So the switch would be on the binding layer and there is no need for programmatic view objects. Unlike in the above blog article, the 3 VO exist in your case so you don't need to create them on the fly. Just change the VO name in the referenced managed bean

View Link on two programmatic view objects

Hello,
I use Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407
I have two programmatic View Objects with data from other sources (an ArrayList in my example).
Now I would like to create a View Link on it. How can I do this?
I'm quite new on Java and ADF...
I know it is possible because I already found Steve's example 132 here [http://blogs.oracle.com/smuenchadf/examples/|http://blogs.oracle.com/smuenchadf/examples/]
But could somebody create a simple example based on my example classes below (which is understandable for a newbie like me ;-) ?
Has been asked already here, but I did not found a solution as yet.

Who can help?
Thnx in advance!

Rolf,
I guess when we try to do it for you, we end up with almost the sample code provided by Steve Muench.
So there from my point of view it doesn't make sense to do it all over.
Take some time and study the sample code, run it without changes and after that try some changes which suits your use case better.
If you don't understand what's going on in the sample post the question here and we try to help you.

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.

Programmatic View Objects + View Links

Ive constructed some programmatic view objects to grab data from 2 custom java business services (for example: Persons and Addresses). The reasons for them being custom and separate are out of my control.
I need to easily represent a relationship between these 2 view objects so Ive constructed a ViewLink between them. However I cant figure out exactly what ADF needs from me in terms of method implementations in my ViewObjects?
When I drop the master data control onto a JSF via a Tree table, it looks as though its not actually filtering the detail rows. I.e. if master is a Person, and detail objects are Addresses, each Person tree node has all Addresses under it. Im assuming this is because the Address ViewObject is programmatic and so ADF doesn't know how to filter the results?
How can I setup this ViewLink between 2 programmatic ViewObjects such that the ViewLink works like its supposed to?

Changing a Programmatic View Object's query at run-time

Hi,
I've created a programmatic View Object using the information in '35.9.3 Key Framework Methods to Override for Programmatic View Objects' in the Oracle Middleware Fusion Guide and bound it to a BarChart. This has worked fine using the following:
String myColumn = "Quant1";
protected void create() {
getViewDef().setQuery(null);
getViewDef().setSelectClause(null);
setQuery(null);
String myQuery = "SELECT Service as MyService, " + myColumn + " as MyValue FROM ColumnTestTable WHERE 1 = 1";
getViewDef().setQuery(myQuery);
setQuery(myQuery);
I also have my data updating automatically. I have public properties in my viewObjImpl class which I can set and update the value of myColumn. I then thought it would just be a case of re-calling the create() method and the SQL would be updated and my chart would auto-update using the new column to select it's values, the value of the property updates and the create method is called but the chart doesn't display any different data and stops auto-updating. Does anybody know if this is possible and if so what I may have missed?
Cheers, Tom

Hi Timo,
I moved everything to a different public method and solved the problem by firing the execute() method which I hadn't been doing previously and the chart updates with the correct data.
However, once I execute the SQL my chart stops auto-updating with changes to the data in the database - do you know how I update the SQL query but keep my chart auto-updating? Perhaps I have to re-register for the registerDatabaseChangeListener for the query collection?
Thanks in advance, Tom

Apply View criteria at runtime to child View object

Hi,
I am facing issues while trying to assign View Criteria to child VO that is part of View hierarchy at runtime.
AM Model:
Parent VO ->
Child VO1
-> Child VO2
View Link between :
Parent VO -> Child VO1
Child VO1 -> Child VO2
I have to apply View criteria at runtime at Child VO1 & Child VO2, i tried setApplyViewCriteriaName from AMImpl for these VO but that doesnt work.
It works for Parent VO, So I concluded Apply VC doesnt work directly for Tree structure.
I then override executeQueryforCollection in the VO however i am never able to get the handle for the VO that is getting executed :
Here's what is happening when i fetch my VO tree from AM :
- Parent VO , Child VO are getting instantiated
- Parent VO executeQueryforCollection called
- ** After this a new instance of Child VO is getting instantiated and i dont have any control of setting the VC based on some custom property
as all get defaulted at this point.
Please suggest what can be done in this case.
PS : i can not hardcode the VC condition at View Link.
- Sam

I was able to set the VC condotinally based on property set at Parent level using following code in executeQueryForCollection :
ApplicationModule am= this.getApplicationModule();
ViewObject vo = am2.findViewObject("ParentView1");
prop = (String)vo.getProperty("Parent_prop");
if(propVo_prop.equals("Y"))
this.setApplyViewCriteriaName("VC");
super.executeQueryForCollection(object, object2, i);
is this the right way ? Any performance bottleneck ? This service can be called for 1000 Id's .
Please suggest if there is some better way.
Thanks
-Sam

Refresh problem by combination of programmatic view and master-detail page

I am using the latest versions of both ADF (10.1.3.2.0.4066) and JHeadstart (10.1.3.1.26) and I have an application with 1 page in which I have as root page a programmatic view (table-form) which I fill with request parameters.
Under that programmatic view I have a master (table) with 3 detail pages (table).
The programmatic view is populated with always 1 row, which goes always correct.
The problem is occuring when iterating through the first entity based master table which contains lots of rows. Then the problem is that when you navigate through the master table the detail pages are refreshed correctly, but when you navigate back to the first row that row won't get updated.
The next thing I tried is create a new jheadstart application with only the master-detail pages (entity based), so without the programmatic view, and then the iterating through the master table and the refresh of the child tables is working correct.
What can be the problem here.

Have you tested this in the ADF Business Components Browser? That's the tester that you can find by right-clicking your ADF BC Application Module and choosing Test. If you go to the View Object instance for the programmatic view, and using the ViewLinks to its children, do you get the same behavior as in the JHeadstart application?
kind regards,

Issue in programmatic view object.

Hi,
I am creating a programmatic view object, in a button's action listener. I have used ViewObject.clearcache() to flush the VO previous data, every time the button is clicked and load new data. The issue which i face, is that the table showing the VO data, shows data in alternate attempts i.e. 1st,3rd and 5th button click and in the 2nd, 4th click it shows "No data to display." . If i try using ViewObject.reset() the table is loaded with data every time but the new result set gets appended, which gives duplicate data.
Please help.

Max

Where the programmatic views will be stored in Database.

Hi, All
what will be the scope of the views which are created programmatically in database.
will they store in any temporary tabels in the database, could anybody provide any Idea.
Thanks in Advance.
Renuka

Renuka,
Even though we do not require any database object like (views / synonyms) to create programmatic view object we need a database connection to initially create the ProgViewObject. From where does your data come from? Other Datasources than DB?
And as you explained ViewObjects will only be occupied in Application Level not in the DB Used for BC Objects.
In that case even if we have ProgViewObjects in BC project in a big number is should not be a performance impact from the Application side on the underlying used DB for that App. Correct???????? Not really. ViewObjects themselves does not need any space in DB (they are simple XML files - with or without related java classes). However, the VO would need to contact the DB for fetching the data. If you are not using the Database (that you've used to create a connection), to fetch the data (and using some other Data Source), then the answer for your question is Yes. There would not be a performance impact on the underlying DB. However, there would be on the Data Source you are using for the Programmatic VOs.

This almost works except when I try to print out the attributes I get an error. I beleive I have to override some of the view object framework methods. If so, how do I go about this? Is it the same methods overridden in this example Getting a View Object's Result Rows from a REF CURSOR? http://radio.weblogs.com/0118231/stories/2003/03/03/gettingAViewObjectsResultRowsFromARefCursor.html

Yes. only difference is that your VO will just have one row in it.

I have checked the validation view and it is returing value with the same bind variable value but is not returning any value when using inside this method validation.
I have checked several times but can't find the fault in the code.
Please help

ViewLink between DB and Programmatic View Objects

Im using programmatic view objects as described in #132 of http://blogs.oracle.com/smuenchadf/resource/examples
I can create view links between these programmatic view objects, but when I create a ViewLink from a DB ViewObject to a programmatic view object, the programmatic one fails to see the view link when invoked, and therefore doesnt return the correct detail objects.
Has anyone created a view link like this before? If so, can I see the code or an example?

If you look at example #132 above, you'll see a ListOfMapsDataProviderViewObjectImpl - which is a custom ViewObject that delivers data programmatically. There's a method in this object "getFilterCriteria(..)" that looks at the parameters delivered to the ViewObject, and any ViewLinks, to produce a map of parameters that the underlying DataProvider can use to filter its data. When you setup a ViewLink between two of these ViewObjects you may see a filter on a foreign key, since the master view object is retrieving its detail objects. However, when the master object is a standard database view object, the view link doesnt work, i.e. the getFilterCriteria method does not see the view link when it calls ViewObjectImpl.getViewLinks().

Crystal Report Viewer Microsoft JScript runtime error

When I use the crystal viewer control to render a report on the screen I receive the following error message:
Microsoft JScript runtime error: Object doesn't support property or method 'isObject' ... and the following line is hilighted:
if(!bobj.isObject(json)).
Here is the markup for the test page I'm using
{<body>
<form id="form1" runat="server">
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"
AutoDataBind="true" ReportSourceID="crSource" />
<CR:CrystalReportSource ID="crSource" runat="server">
</CR:CrystalReportSource>
</form>}
I believe I set all info on crSource correctly (report path etc ...) because If I remove the Crystal reports viewer from the page and just use the crsource (i.e crptSource.ReportDocument.ExportToHttpResponse ...) I can export the report OK. Its only when I have the crViewer on the page Is when I recieve this error.

I am using crystal reports 2008, visual studio 2008, windows 7 pro, MS Sql Server 2005, IE9
I uninstalled crystal reports, and reinstalled crystal reports 2008 sp3 (Full build) - No help
When I goto help about visual studio it says crystal reports 2008 (No specific version info)
Assembly cache on the machine has
12.0.2000.0 and 12.0.1100.00 as the vast majority ... a few (Design and Engine) have older 10.5.3700 and so forth (There are so many)
I found this problem on the web with different solutions involving frame work folder or not having IIS setup to server the crystal reports viewer ... this is happening to me on my local development machine using the ASP.Net Develepoment server included with VS2008 ..
Any help you could give me would greatly be appreciated
Thanks in advance
Kevin

Hi Kevin,
Take a look at below SAP Note.
[1531003 - Error: bobj undefined - javascript error |http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333533333331333033303333%7D.do]
I got this result just by searching 'bobj is undefined javascript' in the top right search box.
Thanks,

Bug in bc4j?, view links at runtime, multi table relationships, accessor name

The following seems like a bug in the business components framework
to me:
To make things simple, I will use view objects aV, bV, cV,
corresponding rows aR, bR, cR and row iterators aI (not used though),
bI, cI.
I create two view links from aV to bV and from bV to cV at runtime,
with the accessor names "Bs" and "Cs".
ViewLink a2b = createViewLinkBetweenViewObjects(..., "Bs", ...);
ViewLink b2c = createViewLinkBetweenViewObjects(..., "Cs", ...);
First of all this code works perfectly fine:
ViewObject aV = a2b.getSource();
ViewObject bV = a2b.getDestination();
ViewObject cV = b2c.getDestination();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
while(bV.hasNext())
Row bR=bI.next();
System.err.println(" bR");
while(cV.hasNext())
Row cR=cI.next();
System.err.println(" cR");
Using the accessor name "Bs" at the first level is ok, too:
ViewObject aV = a2b.getSource();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
RowIterator bI=(RowIterator)aR.getAttribute("Bs");
while(bI.hasNext())
Row bR=bI.next();
System.err.println(" bR");
HOWEVER, USING THE ACCESSOR "Cs" AT THE SECOND LEVEL OF THE MULTITABLE
RELATIONSHIP IN THE FOLLOWING CODE, GIVES ME AN EXCEPTION
oracle.jbo.NoDefException: JBO-25002: Definition Cs of type Attribute
not found. THE SEEMS LEGAL USAGE OF THE ACCESSOR "Cs" TOO ME THOUGH,
THEREFORE MY SUSPICION OF A BUG.
ViewObject aV = a2b.getSource();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
RowIterator bI=(RowIterator)aR.getAttribute("Bs");
while(bI.hasNext())
Row bR=bI.next();
System.err.println(" bR");
RowIterator cI=(RowIterator)bR.getAttribute("Cs");
while(cI.hasNext())
Row cR=cI.next();
System.err.println(" cR");
(By the way, could make your window for filling in the message a little bit wider,
making it easier to cope with the line breaks).
Feedback is appreciated.

Your results are as expected per the imlementation. Basically you've established (two) ViewLinks between two sets of two instances of VOs.
Now you try and get an accessor to return a set of details. You need to establish a link between that detail set and it's details to use the accessor on the second detail to get the desired results. Basically you've to establish the chaining between appropriate instances of VOs and not just the outer VOs or VO members of your AM.
