POJO Data Control Error Handling

Hi.
I have POJO Data Control on Model.
Now everytime this data control thorws exception (JboException) on ViewController I get two errors like:
ValidationException: Exception Description: My JboException error
... (Stacktrace)
Caused by: java.lang.reflect.InvocationTargetException

     ... 75 moreWhat is proper way of handling exceptions in POJO Data Controls?

Hi,
any exception that is thrown by the data control is passed on to the binding layer to display the exception (if dc is accessed through the binding). So how do you access the POJO DC when the exception is thrown?

Any Examples of using ActiveCollectionModelDecorator with POJO data control

Are there any Examples of using ActiveCollectionModelDecorator with POJO data control in any of the sample packs?

OK, here's an quick example. Create a new Windows Forms application and add a ScatterGraph and a Label to the form. Add a cursor to the ScatterGraph, then add the code below to the form. This generates 50 random data points when the form is loaded and plots them, then uses the cursor's AfterMove event to display the current X and Y positions in the label. Here's the code:
Private Sub OnFormLoad(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Const dataLength As Integer = 50
Dim xData(dataLength - 1) As Double
Dim yData(dataLength - 1) As Double
Dim rnd As Random = New Random
For i As Integer = 0 To dataLength - 1
xData(i) = i
yData(i) = rnd.NextDouble() * 10
Next
ScatterGraph1.PlotXY(xData, yData)
End Sub
Private Sub OnAfterMoveXYCursor(ByVal sender As Object, ByVal e As NationalInstruments.UI.AfterMoveXYCursorEventArgs) Handles XyCursor1.AfterMove
Label1.Text = String.Format("({0}, {1})", e.XPosition, e.YPosition)
End Sub
Hope this helps.

How to cause POJO data control to use custom base ViewObject class

ADF 11.1.1.4
We have a POJO data control that displays data in a table. We can filter the table using the column filters and this performs in-memory filter. If an exception occurs I see that it is using a ViewObject for the in-memory filtering because this shows up in the stack trace.
oracle.jbo.server.ViewObjectImpl.rowQualifies(ViewObjectImpl.java:2811)
It uses DCDataVO which extends ViewObjectImpl
We have a Custom base view object defined that all our normal view objects inherit from, defined in Project Properties/BC/Base Classes
Is there any way to make the DCDataVO also extend from our Custom View Object that inherits from ViewObject so that we can override methods? For example if I wanted to customize the rowQualifies method.
In DCBeanDataControl.Java I see where it actually gets created.
vo = DCDataVO.createViewObjectFromDef(vdef, this, getApplicationModule());

So you have already overridden then rowQualifies() method in your custom base View Object ? Are you calling super in that ?

Managed Beans vs. POJO Data Control for sharing data

Hi,
I am currently using JAX-WS proxy client and POJO Data Controls to retrieve data from web services. This data needs to be shared across users. Normally I would use application scoped managed beans for this, but since I prefer using data controls and the binding layer, would using static POJO Data Control classes achieve the same thing?

Hi,
Data Controls don't exist across user sessions so in your use case use a managed bean in application scope. If you want to make this available from a Data Control
- create a POJO
- Use EL in the POJO to access the managed bean
- Create a DataControl from the POJO
This way the Data Control exposes the data as an API but itself always reaches out to the managed bean as a data store/cache

Create dynamic table using pojo data control

What are the options we can in order to create dynamic table columns based on pojo data control?
We have a class A and there are some attributes say A.x, A.y, A.z
Within class A, we have a collection of class B and has attribute say B.k
Within class A, we have a collection of class C and has attribute say C.j
Every instance of class A has same number of instances of class B
Every instance of class A has same number of instances of class C
We would like to display a table like this
A.x, A.y, A.z, [B.k, B.k, ...], [C.j, C.j, ...]
How should we do that?
Thanks

I'm using ADF + Toplink + Session EJB in jdeveloper 10.1.3.0.4 . After creating POJO files
(A little time ago, I have getting the error in thread : Null Pointer exception in ToplinkDataControlProvider but I have passed this error message) I tried to create xml file descriptions for POJO files. To do this, I have chosen "create data control" option but gotten the below error message in message window :
What can be the problem. I have controlled mapping file, there is no problem in mapping status also make and rebuild the model package there is no error message.

This methodAction calls a Data Contol based on a POJO which is using a JAX-WS Proxy. This Data Control POJO is packaged in a separate JAR file named ServicesProxy.jar.
Both ServicesProxy.jar and the ADF application using it are deployed as two distinct shared libraries used by webcenter portal application.
An important information is that the error does not happen when debugging the ADF application on my IntegratedServer. The error happens only when deployed as a shared Lib used by webcenter portal application.
This jar file ServicesProxy is used by other applications within our portal, so I think that the data control is properly created.
Do you have any idea what could be the cause of such error?

Web Service Data Control error

I was folllowing the instructions on this demo for web service data control.
http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/WSDataControl/WSDataControl.htm
For some reason I am getting the following error right when the page loads.
'GetLatByZipCode' expects parameter '@zipCode', which was not supplied.
Here is the entire error stack. Any idea why it is doing this:

OK

I would recommend that rather then working according to the demo you actually follow this tutorial:
http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_52/jdtut_11r2_52_1.html
Which in the last part shows you how to use the Web service data control against a service you'll build.

Clear POJO Data control cache

Hi I am using Jdev 11.1.1.7
I have a POJO based Data control which am using for tree structure.
I have this tree inside a popup.
So when cancelling or after the purpose of the popup is over.
I want to clear the cache of the data control.
I tried several ways to do that like having a methods in my java class where making the object null and calling the methods on cancel.
But nothing worked .
How to clear the Pojo DC.

Hi AlejandroTLanz ,
I tried the above method.
I created a method in Java class which is used to make the List null used by the tree.
And then calling finditerator.executequery.
I could see that the list is getting null.
But In Java sampler It still shows that Objects are present.
I guess the Object are still in data control cache...
I tried to clear the DC Cache by calling the DC.resetMethod.
But nothing worked

HELP!! - Pricing Date Control error

Hello experts,
I have a problem with pricing date control.
I would like to set Pricnig date control=5(GR Date)in Vendor master.
However, if I do so, I get an error in MIGO-GO said"Transaction cannot be posted due to errors in price determination:MSG no. ME573"
I don't have a problem if I set Pricing Date Control anything other than "5".
Where should I customize(IMG) to fix this problem?
This is very important, so I would like to rewards points to those who give me valuable answers.
Thanks in advance,
YO

Hi,
Please check info record Pricing date control and Purchase order Price date control in Item details>more functions
Following will help you tounderstand more on this
In the automatic price determination process, the price can be calculated as at the document date of the PO, or as at another date (such as the current days date, the delivery date, or the goods receipt date). You can specify the date to which the price that is determined relates at the following points:
In the vendor master record, in the Pricing date control field, if you wish to use the same price determination date for all a vendors materials.
In the purchasing info record, in the Pricing date category field, if you wish to use a different pricing date for a certain material supplied by a particular vendor.
The value in the purchasing info record takes precedence over the value in the vendor master record.
In the purchase order, in the Pricing date category field (found via Item > More functions> Additional data).
The value from the info or vendor master record is preset when a purchase order is created. However, this is only used if you change it in the purchase order and carry out a new price determination process.
The pricing date category in the PO takes precedence.
Example:
In the info record, you have specified that the price determination process is to be carried out with the conditions that are valid on the delivery date (pricing date category 2). Furthermore, you have created two validity periods (from 04. 01.1997 until 04. 31.1997 and from 05. 01.1997 until 12. 31.1997), each with different conditions.
You create a purchase order with the delivery date 05.05.1997. The pricing date category from the info record is adopted. In the course of the price determination process, the info record conditions from the validity period 05. 01.1997 until 12. 31.1997 are then adopted.
If you wish to adopt the info record conditions from the first validity period in the purchase order, you must change the pricing date category in the PO to blank and carry out a new price determination process.
Hope this will help to resolve your issue

POJO Data Control af:table with selectOneChoice

Hello All,
JDeveloper 11.1.1.6/7
I have a peculiar issue that I am trying to solve.
I have a POJO based data control and an af:table based out of it. One of the fields (category) is to be a selectOneChoice driven by a WS Data Control. When I drag-drop the target attribute (category) as a Select One Choice and create a dynamic list based on the WS Data Control the row becomes uneditable.
The selectOneChoice from the jspx:
          <af:column headerText="#{bindings.children.hints.category.label}"
                     id="c3">
            <af:selectOneChoice value="#{row.bindings.category.inputValue}"
                                label="#{row.bindings.category.label}" autoSubmit="true"
                                required="#{bindings.children.hints.category.mandatory}"
                                shortDesc="#{bindings.children.hints.category.tooltip}"
                                id="soc1">
              <f:selectItems value="#{row.bindings.category.items}" id="si1"/>
            </af:selectOneChoice>
          </af:column>
The relevant sections from the pageDef are as follows:
<tree IterBinding="childrenIterator" id="children">
      <nodeDefinition DefName="info.bijesh.samples.ws.model.Children"
                      Name="children0">
        <AttrNames>
          <Item Value="id"/>
          <Item Value="name"/>
          <Item Value="category" Binds="category"/>
        </AttrNames>
      </nodeDefinition>
    </tree>
<list IterBinding="childrenIterator" id="category" DTSupportsMRU="true"
          StaticList="false" ListIter="ReturnIterator">
      <AttrNames>
        <Item Value="category"/>
      </AttrNames>
      <ListAttrNames>
        <Item Value="categoryCode"/>
      </ListAttrNames>
      <ListDisplayAttrNames>
        <Item Value="categoryDisplay"/>
      </ListDisplayAttrNames>
    </list>
If I remove the Binds attribute from the Item definition, then the row becomes active but of course the drop-down list is empty. Any ideas on what I am doing wrong. I have uploaded the sample workspaces here - http://www.bijesh.info/bijesh/ADFWS_TestCase.zip. WebServiceHost contains the LOV Web Service and the WSClient workspace contains the test page.

Hi,
there is a bug I filed this week on that issue. Could it be you filed the issue as a SR with support? Because this is where I got the test case from. For me the problem reproduced witha static list as well. So if you want to check if this is the same you see, please try a static list in the SOC. If this too makes the field un-editable then its the same effect. The testcase I had was 11.1.1.7 and I fixed an issue in its POJO model to run the sample (just in case you belong to the same customer). I didn't test with 11.1.1.6 as obviously the bean data control is different in 11.1.1.7 (at least it complained about a missing class when I tried in 11.1.1.6).
If the testcase I true is not yours, please contact customer support with your test case or send it my way in a zip file renamed to "unzip"

Numeric control error handling

Hi all,
I have two question about numeric control.
1) "How to handle invalid inputs?"
Let say, I have one numeric control that can only accept 0 to +inf (Range). So negative input will be invalid data input. Whenever I typed the negative value on it, this control automatically changed back to default (min) value. What I want is that. Is there anyway to detect invalid user input? So that I can program whenever user input negative number, it will automatically change back to previous valid input (not default value).
2) "How to assign the dynamic range of numeric control?"
I used property node to assign the range but my problem is that. I assigned min 0.1, max 1.2 and increment 0.1 but I cant able to select 1.2 or sometime 0.1 by using increment/decrement arrow. Maybe because of floating points? And also I want to do when user input overrange value (eg.1.3) by typing, the value should go back to previous valid input.
Any idea? Thanks

You can choose how LV will react on entries exceeding a limit. The default is, that LV coerces the value to the limit. But you can also ignore the limit and the user can enter any value.
Nevertheless, if you ignore the limits, you always have to check in your software for invalid values!
Regarding 2) i couldn't reproduce what you described. Maybe you should post a little example....
For the 2nd part of your question, please see my answer above...
hope this helps,
Norbert

Calling webservice in code using data control ADF Mobile

Hi,
I am calling webservice in code using data control. Below image is show my binding.
https://www.dropbox.com/s/ufjnnd67mfaeucq/Snap%202013-05-13%20at%2011.49.17.png
My code is :
ValueExpression ve1 = AdfmfJavaUtilities.getValueExpression("#{bindings.WeatherDescriptionIterator}", AmxIteratorBinding.class); // Using IteratorBinding
AmxIteratorBinding iter = (AmxIteratorBinding) ve1.getValue(AdfmfJavaUtilities.getAdfELContext());
GenericType row = null;
iter.getIterator().first();
iter.release();
for(int i = 0; i < iter.getIterator().getTotalRowCount(); i++)
row = (GenericType)iter.getCurrentRow();
Integer s = new Integer(i+100);
row.setAttribute("deptId", s);
This code is work fine in POJO data control. But When I used this code for calling webservice data control then i get following error.
can not find property bindings.
And I also use below code but same error occur.
ValueExpression ve1l = AdfmfJavaUtilities.getValueExpression("#{bindings.WeatherDescription.collectionModel}", AmxCollectionModel.class); // Using CollectionModel
AmxCollectionModel model = (AmxCollectionModel)ve1l.getValue(AdfmfJavaUtilities.getAdfELContext());
Object[] myArr = model.getKeys();
for (int x = 0; x < myArr.length; x++)
Object myObj = myArr[x];
Map provider = (Map)model.getProviders().get(myObj);
String deptName = provider.get("deptName").toString();
}

!!!! IMPORTANT !!!!
The use of +*#{data.view_FlexFieldDisplayPageDef.publicflexfieldflow1.regionModel}"*+ in your code is an *absolute no-go and serious coding issue* as there is no guarantee that this PageDef file exists in the application you use the declarative component in. Even if you don't plan to use the declarative component anywhere else, you should pass the model reference as an input attribute to the declarative component so it can be configured by each use of the component

Should we really go for bean data controls for a new project?

Hi,
I am still new data controls and trying to figure out the advantages of using bean data controls for our new project. Our UI is going to have customized UI components and our back end is going to be a tcp/ip server.
Is it a good idea to develop java beans and then create data controls to bind to UI layer? I think it makes sense to use data controls if we want to use existing java beans. Maybe we would be separating the model layer by using data controls, but only thing it would be doing for us would be the simple object calls to my java beans. Would it be better to use data controls or use I choose to make object calls?
Thanks,
Manoj

Hi,
the POJO data control will always give you a benefit and develope productivity, unless what you have to build fits on a single page - in which case you may not mind the burdon of manual UI component binding
