Accessing setters in parent view object through view link

Hi,
I want to access the setters in a parent view object from a child view object through the view link. I have not been able to find an example, can someone point me to one? This is possible isn't it?
Thanks,
Jim

View Object in the link - CREATION

Below is the table schema. master1, slave2, cat3 are in the LINK.
Master1 -----> Slave2 ------> Cat3.
(id) (id, masterId) (id, slaveId)
We are having the UIX pages to traverse starting for Master1 and down to Cat3.
We need to have a url that takes us directly to the Cat3 UIX page.
ex : www.something.com/catsBrowse.do?catdId=xxx&slaveId=yyy&masterId=zzzz.
I am trying to initialize the view object. But on executeQuery(). It gives an exception.
How do I initialize it. Is there any samples available???
- Thanks.

Hi,
using ADF:
1. Create a page that shows data for cat3
2. Using the ADF binding (e.f. accessing it from a Struts Action) obtain teh iterator for master1 and set it to a specific row.
3. Do the same for Detail 2
4. Navigate to page cat3
Note that you don't need to access teh VO drectly but can handle this all through the binding framework

[SOLVED] Multiple Dynamic View Objects and View Links - ADF Tree Table

Hi all,
I've got a method that creates 3 dynamic viewobjects using this:
            ViewDefImpl Level1ViewDef = new ViewDefImpl("Level1View");
            Level1ViewDef.addViewAttribute("LevelDescription","LEVEL1_DESCRIPTION",String.class);

Which is better creating view accessor based on view object or view instanc

When creating view accessors whether in the entity object or in the view object, we have two options:
1- create the view accessor based on a view object.
2- create the view accessor based on a view instance.
what are the differences between these two options?
what are the cases where I should only use option 1 or option 2?
which one is better?

Hello Timo,
I will try to explain my question better.
when we create view accessor, after click on create new view accessor icon, the create view accessor window is opened, at the header of this window there is a statement says:
Select a view object or shared view instance and shuttle it to the selected list to create a view accessor.
and here is my concern, which one to use
1- select a view object from one of the available view object and shuttle it to the selected list.
2- select a view instance from the application module and shuttle it to selected area.
If you have FOD sample (and I am sure you have it :) ), I see that oracle team has used both of them in different places, for examples
1- in oracle.fodemo.storefront.entities.PersonEO all view accessors are created from view instance in SharedLookupService application module.
<ViewAccessor
    Name="PersonTypesVA"
    ViewObjectName="oracle.fodemo.storefront.lookups.LookupsBaseVO"
    AMUsageName="SharedLookupService"
    ViewInstanceName="PersonTypes"/>is it because they are used to create LOV?
2- in oracle.fodemo.storefront.entities.OrderEO the view accessor is created from a view object, not from instance inside application module.
    <ViewAccessor
    Name="OrdersVO"
    ViewObjectName="oracle.fodemo.storefront.store.queries.OrdersVO"/>I couldn't find the usage of this accessor?
Hope it is clear now.

Changing the Updatable property of a View Object Attribute through code

Hi,
Is there a way to set the "Updatable" property of an attribute in a view object through code ?
I checked the API docs for the AttributeDef class but there is no method to set this. there is a constant (UPDATEABLE_WHILE_NEW) which gives the current value.
My requirements in short - I have a ADF editable Table. Based on a flag whether it is SET or NOT, i need to make a particular column such that the inputTextBox on this column must appear for only the new rows inserted into the table. For all the existing rows users should not be allowed to edit values on this column.
I know this can be controlled with the UPDATABLE property on the attribute in the view object by setting the value as "WHILE NEW".
Now i need to control this through code at runtime.
Please let me know on ow to do this.
JDev version: 11.1.2.3
Thanks.

the method you are looking for is available in the AttributeDefImpl class which you can get from the EntityImpl like
this.mDefinitionObject.getAttributeDefImpl("YOUR_ATTRIBUTE_NAME").setUpdateableFlag(AttributeDef.UPDATEABLE_WHILE_NEW);

Accessing View Object Information from JSP

Hi!
I know that my question it's a basic one, but I'm having some problems. Let me start by describing my problem.
I need to implement an navigation select box to one table (this table will be a result of a query). I'm "building" the select box with a <c:forEach> iterator. Well, the problem starts where:
<%-- Makes a kind of Math.ceil(double) --%>
<c:set var="resultInDouble" value="${(binding.estimatedRowCount-1)/binding.rangeSize +1}" />
<c:set var="resultInDoubleZero" value="${resultInDouble - resultInDouble % 1}"/>
<fmt:formatNumber value="${resultInDoubleZero}" var="resultInt" pattern="0"/>
<select name="select" >
<c:forEach var="SelectBoxItems" begin="1" end="${resultInt}">
</c:forEach>
</select>
As you can see, first I need to calculate the number of "<option> ... </option" I need to put on the select box, and I do that by making an ceil method emulation (for those that doesn't know ceil, it rounds up a division, like 7/3 = 3). To do this ceil I need to call the estimatedRowCount. And that's the problem: when I call estimatedRowCount, the query that I previous made is repeated to calculate the numberOfRows returned. As you can imagine, I don't want to re-execute the query, but only get the number of all rows.
One solution that I thought, was in the Java Controller File for this page, use the method associated with the ViewObject getRowCount(), that doesn't re-execute the query. With this idea, I would construct the select box with java code, something like this:
<select name="select" >
<%
int ceilResult = Math.ceil(viewObject.getRowCount(),viewObject.getRangeSize());
for (i = 0;i<ceilResult;i++) {
%>
<option> ... </option>
<% } %>
</select>
But with this idea, I hanged with a problem: "How do I in JSP, can "see" the view object?".
Basically i only need a small example source, that in Java Controller File can get the iterator to make the return of the ViewObject getRowCount method.
Does anyone have any idea how to solve this problem, or maybe a new approach ?
Tiago Soares
P.S. I've already tried some others (attempts of) solutions, but they didn't worked. I didn't posted their description, because I was afraid that anyone would read this post, because of the size of it. :)

First of all, please stop reposting this question. Post it once and someone will probably reply to it.
Secondly, you can expose methods of a view object through it's dialog (I think) or you will have to do it in the Application Module.. But it may suit your need better to create a transient column on you VO (one that exists only in memory) and store your value in that.

Please have BPEL loggers both at domain and system level to DEBUG mode. Set all loggers to DEBUG as you are interested to see the entire sequence flow..however, some loggers give you unnecessary info ;/ apart from cube, activation, delivery, dispatch, persistence.
Added to this, you might want to try SOAPUI, Fiddler, HTTP Analyzer.

Need help on how to specify the current select row in a View Object

Hi,
I have a ADF table on my page, when I was selecting the rows in this table, I want the set and get methods in the ViewRowImpl class to do some customized actions. I found out that each time regardless the row I select in the table, the viewrowimpl class will always return the data in the first row, I tried to use getCurrentRow in VO row impl. but still, gets the first row.
Does anyone know how to get the selected row value in the View Object, or View Row Impl rather???
Thanks!

Hi,
you can call a method exposed by the AM and pass teh rowKey of the selected row as an argument. When you configure the exposed AM method in the pageDef (creating a method binding) the argument is shown in a dialog from where you can use EL like #{bindings.iteratorName.currentRow.rowKey} to access the current selected row.

Problem exposing Accessor Methods on View object (ViewRowImpl.java)

JDeveloper 9.03
I have a view link, ViewLinkSourceDest, that links two view objects Source and Destination. Each view object has its respective ViewRowImpl.java file created.
I have selected "Generate Accessor in View Object" in View link Properties of the View Link Wizard for both source and destination view objects.
The correct Accessor methods are available in both the source and destination ViewRowImpl files.
When I access the Source accessor method from the DestinationViewRowImpl object I receive the following error:
          ORA-00904: invalid column name
          It is also is displaying the Source view object's SQL statement with the (:1 = Destination.ID) where clause.
The error is occurring when trying to retrieve the view object using this type of method call:
          Row r = this.getSourceView();
After further investigation I have found an example set of view objects in which the error does not occur. The difference was in the ViewLink.xml file.
The ViewLink.xml file that accesses the Accessor with the error begins like this:
          <ViewLink
               Name="ViewLink"
               Where=":1 = Destination._ID" >
The ViewLink.xml file that accesses the Accessor with no error begins like this:
          <ViewLink
               Name="ViewLink"
               EntityAssociation ="SourceDestAssociation" >
suggesting that the use of an association would resolve this problem.
I was not able to create a View link based on an association that would generate a ViewLink.xml file that ressemble the successful file above. I could however manually add the correct entry to the xml file that caused the error and sucessfully access the Accessor method in the source object. This is not the final answer because the IDE will regenerate the ViewLink.xml file to its original state even if created with the appropriate Association.
Is this a bug?
Is the way the ViewLink.xml file created different in JDev 9.03 than in 9.02
Is there something I am missing that is causing the ViewLink.xml file to generate incorrectly?
Any suggestions would be helpful.
Rob

Steps to recreate:
1 Create SomeSuperEntityImpl.java extended by SourceEntityImpl.java and DestinationEntityImpl.java entity objects.
2 Create SourceView and DestinationView objects
3 Create SourceDestinationAssociation linking the entity object Source PK to Destination FK
4 Create SourceDestinationView linking Source and Destination view using the SourceDestinationAssociation
View the SourceDestinationView.xml file and you will see that the viewlink has Where=":1 = source.src_id"
This is the scenario that causes the initial problem with the Accessor Methods.
If the SomeSuperEntityImpl.java is removed as the super class and the same procedure is followed you will get the desired 'EntityAssociation = "package.SourceDestinationAssociation"' in the SourceDestinationView.xml file .
Hope this is a little clearer.

How to access View Context thr' View Controller; and not thr' View....

Hi
As we know that we can access Component Context Attribute by Component Controller in view as:
wdThis.wdGet<Component_Name>Controller().wdGetContext().currentContextElement().
get<Component_Context_Attribute>
whereas wdThis.wdGet<Component_Name>Controller() is the Component Controller.
So, in the same way, I was just wondering do we have any way to access the View Context through View Controller.
Generally for view context, we use wdContext which is (= wdThis.wdGetContext() ) means accessing view context thr' view.
i want to access View context thr' View Controller which is wdThis.wdGetAPI().
Thanks....

View objects, view links, does not search properly

Hi,
I am using Jdev 11.1.2.0
I have created a search criteria based on view objects and view links. It has entities and entity associations as base. The structure is as follow:
vo1 ->vl (1 to 1) - > vo2
->vl ( 1 to many) -> vo3
Any search attribute which is not from vo1 return bad result. It happens in running app module and in the jspx page. In app module, it sometimes complains about populating the wrong attribute for the named criteria.
The search criteria is using "exists" statement for vo2 and vo3 for adding the conditions. It has many attributes within the exist statement.
So what is the problem. Why it does not join properly? Why does it return bad result when search attribute is from vo2 and vo3? Please help.
Any more information requires to solve the problem?
Thanks,
Arthur

Hi,
Two more information: vo1 is composed of Entity1 (1..M) Entity2 and Entity1 (1..1) Entity 3. vo2 is composed of Entity 2 and vo3 is composed of Entity 4.
I follow the information from http://download.oracle.com/docs/cd/E16162_01/web.1112/e16182/bcquerying.htm#BCGIFHHF
to create the search criteria.

Can Data Links be established between Data sets based on View Objects?

Hi all,
In the BI Publisher Documentation it's given that Datasets based on view object queries do not support Data Links / Group Links. We found out that only way to establish relationship between view object Datasets is to create a view link and then upload it to create a Dataset.
1. Is there any other way to establish relationship between view objects Datasets in DataModel editor itself just as in the case of data sets based on (SQL queries e.t.c.)?
2. If so can View object Datasets be linked to Datasets based on other Datasources?
3. Will the Datalinks for View object Datasets be supported in any of the upcoming releases. Is there any ER logged for this case?
Any insight on the above issues will be really helpful.
Thanks

Enhance the data source with date and time and populate these fields in the user exit using the function module IB_CONVERT_FROM_TIMESTAMP .
OR
You can create Z function module IB_CONVERT_FROM_TIMESTAMP in BW side and write a routine in update rules/transfer rules to populate date and time.
hope this helps ...

Dynamic view object loses bind variables after passivation

I am creating a view object definition/view object programmatically in Jdev 11.1.1.2.0. The query requires a named bind parameter. All was working fine but now I am testing with app module pooling disabled and the bind variable is not being restored after passivation -- it's like the definition has disappeared or something.
Here is my VO creation code:
ViewObject vo = findViewObject("FinalistsWithEvalDataVO");
if (vo != null){
vo.remove();
ViewDefImpl voDef = new ViewDefImpl("FinalistsWithEvalDataVODef");
     // I add a bunch of viewAttrs here...
voDef.setQuery(fullQuery);
voDef.setFullSql(true);
voDef.setBindingStyle(SQLBuilder.BINDING_STYLE_ORACLE_NAME);
voDef.resolveDefObject();
voDef.registerDefObject();
vo = createViewObject("FinalistsWithEvalDataVO", voDef);
vo.defineNamedWhereClauseParam("Bind_SchlrAyId", null, new int[] {0});
vo.setNamedWhereClauseParam("Bind_SchlrAyId", new Number(1)); //For testing
vo.executeQuery();
The query executes fine right there and then the VO seems to passivate fine. I even see the bind var in passivation:
<exArgs count="1">
<arg name="Bind_SchlrAyId" type="oracle.jbo.domain.Number">
<![CDATA[1]]>
</arg>
</exArgs>
But then when it reactivates prior to rendering the page, it invariably throws a missing parameter exception and this in the log:
<ViewUsageHelper><createViewAttributeDefImpls> [7409] *** createViewAttributeDefImpls: oracle.jdbc.driver.OraclePreparedStatementWrapper@1af78e1
<ViewUsageHelper><createViewAttributeDefImpls> [7410] Bind params for ViewObject: [FinalistsWithEvalDataVO]AwardViewingServiceAM.FinalistsWithEvalDataVO
<ViewUsageHelper><createViewAttributeDefImpls> [7411] ViewUsageHelper.createViewAttributeDefImpls failed...
<ViewUsageHelper><createViewAttributeDefImpls> [7412] java.sql.SQLException: Missing IN or OUT parameter at index:: 1
I have worked on this for hours and can't see anything wrong. Like I said, it works fine when not forcing passivation...
Any help would be appreciated.
Thanks.
-Ed

@Jobinesh - Thanks for the suggestions. I have read all the documentation I can find. Everything works fine without passivation. Everything still breaks with passivation. I have given up on trying to get the bind variable to restore after passivation and am currently just building the query with all values embedded in the query rather than bind variables. This is bad practice but avoids the problem. However, now that I avoided that obstacle, I'm on to the next issue with passivation of this dynamic view object, which is that the current row primary key apparently cannot be reset after activation. I get the following error:
<Key><parseBytes> [7244] Key(String, AttributeDef[]): Invalid Key String found. AttributeCount:1 does not match Key attributes
<DCBindingContainer><reportException> [7254] oracle.jbo.InvalidParamException: JBO-25006: Value 00010000000A30303033383133343734 passed as parameter String to method Constructor:Key is invalid: {3}.

     at oracle.jbo.server.ViewRowSetIteratorImpl.activateIteratorState(ViewRowSetIteratorImpl.java:3877)
I've been trying various workarounds for over a day now with no luck. Very frustrating.
Thanks for trying to help.
