Retrieving the view object associated to an entity

Hi,
Is there any way to retrieve the ViewObjectImpl or the ViewRowImpl that holds the instance of a particular EntityImpl.
I'm doing some operations an EntityImpl instance, and I need to refresh the view that holds that instance. How can I retrieve it ?

Dwarven,
There may be many View Objects associated with a given entity object. You can determine programatically which EO's are referred to by a given VO, but not to my knowledge, the other way around.

RowSetInfo; bc4j; how to get the View Object

So I'm trying to get/update/insert/delete records in a database that contain an interMedia image in a blob.
I've figured out that I can't simply set the ImmediateAccess attribute. It doesn't like that...
So I'm trying to go after the view object, since the interMedia white paper uses a VO row setAttribute to accomplish the write.
RowSetInfo extends ResultSetInfo which has a method getViewObject(). Cool.
So I try it... and get an error that getViewObject() has protected access.
Anyone know what I am doing wrong? Or should I be even taking this approach?!?!?!
If I go exclusively with the VO layer... how do I preserve the navigationBar functionality? Or do I need to roll my own?
( NOTE: This hilights another example of the perception of 'friction' between rowsetinfos and the view objects/entity objects. An approach that makes "sense" to me as a naive novice didn't pan out. And oddly, most of the bc4j examples go against VOs when, if you are an application programmer, you may never see or use the VO methods ( although it looks like we should be)... we're working at the ResultSetInfo layer. )
Is the the observation of other folk who are building Java Applications/Applets? Or do you all work directly with VOs instead of going through the ResultSetInfo "layer"?

Here is some sample code that I am currently working on and will post on OTN when complete. The code shows how to access a BC4J Domain based on an Oracle type. Working with interMedia is similar since interMedia utilizes Oracle Object types. Please note that I have not tested this yet against interMedia, but I'm hoping that you may find the general process useful.

Problem with 2 View Objects based on One Entity -Probably a Bug in ADF BC

Hi
I am using JDeveloper 10.1.3(SU5) and adf faces and ADF BC and to explain my problem I use HR schema.
First, I created 2 view objects based on countries table named as TestView1 and TestView2. I set TestView1 query where clause to region_id=1 and TestView2 query where clause to region_id!=1 in the view object editor and then I created 2 separated form on these 2 view objects by dragging and dropping from data control palette.
Now when I insert a record in the form based on TestView1 with region_id set to 1 and commit the record and go to the next form I can see the record in the second form which is completely wrong since it is against the where clause statement of the second form.
I am really confused and the situation is very wired and it seems to me something like bug in adf bc.Am I right.Is there any work around or solution for solving this problem.
Any help would be highly appreciated.
Best Regards,
Navid

Dear Frank,
Thank you very much for your quick response.
Reading your helpful comments now I have some questions:
1- I have commited the record in the database so shouldn't the query of view objects be re-queried?
2- We try to use ClearVOCaches (entity_name,false) in afterCommit of the base entity object but unfortunately it does not work correctly. after that,We got root app module and used findViewObject method to find all the view of that entity (we have found them by using name not automaticlly) and called executeQuery of all views. From my point of view it has 2 big disadvantages. First suppose that this entity is an important entity and 4 or 5 viow objects are based on it. Now, For inserting one record we should re-execute 4 or 5 view which I think makes some performance issues. Besides, If during the development one programmer add a new view object based on this entity and don't add the executeQuery in the afterCommit for this view, again we have the same problem. Isn't there at least a way that automatically refresh all related view objects however the performance issue still exists.
3- You mentioned that this issue is handled in the developer guide. Could you kindly give me a refrence which developer guide you mean and which section I should read to overcome this problem.(I have ADF Developer's Guide for Forms/4GL Developer's Guide , however I search for clearVOCaches and surprisingly nothing was found!!!)
4- Could you please give me some hints that from your point of view what is the best method to solve this problem with minimum performance effect.
Any comment would be of some great help.
Thanks in advance,
Navid

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.

Keep the record in the view object if deletion failed.

I have a view object which is based on the entity object, when I am trying to delete a row it failed because it has a child record associate with. I know the row is not delete from the database, but the record is deleted fromt the view.
How to keep the record in the View object if delete failed?

Hi,
the row is not delete from the database,refresh the view . re-execute query and the view show the row

All the properties are not displying for the View Object

i my one of the view Object it is only showing the properties
Values
Lable
Render values
I want to use text box (Input box )...but it is not showing in the property window
why it is not showing the all the properties for the that view Object.
Is it a read only view object ? if so then how to change it

This question is confusing.
You talk about properties, suggesting attribute properties are not showing up in the view object editor. Then you talk about a read-only view object, which suggests you talk about a running application?
Normally a view object is updatable when it is based on an entity object and when on the entity object tab of the view object editor (the page in which you select the entity object) the updatable checkbox has been checked.
But being updatable as such is not why attributes would not show up in a screen.
Can you be more specific, and also tell us what JDeveloper version you are working with?

I want both the entities in the view object to support creating new rows but when i give create insert it allows to insert only on the parent and not the child. I found this link
http://docs.oracle.com/cd/E21043_01/web.1111/b31974/bcadvvo.htm#CEGCAJCI which overrides the exiting classes. but i would like to do it declarative . Is there any other way to do it?
I am using Jdeveloper 11g version 2.
Thanks in advance,
Rakesh

But when i tried to add a new row it showed this error
oracle.jbo.AttrValException: JBO-27014: Attribute LookupTypeId1 in FoundationModuleAM.VikLookupTypeBaseVO is required.

How to get the view Object in UserDefined Action

Hi All,
Any body tell me how to get the view object , like the view object avilable in the wdDoModifyView() method as parameter.
I have requirement like, i want to change the , no of rows displaying in the table should be changed at the runtime based onthe no of rows selected in the dropdown box.
The action which i created will be assigned to that dropdown box, on select of the available option, i will get the view object and change the properties of the "maxrows" of the table .
so for getting the view object in the the Action methods tell me what is the procedure for getting the current view object.

Hello Vishal,
Simply create a value attribute (say rowCount) of type 'integer' and bind it to the 'visibleRowCount' property of your table. Then, in the actionHandler get the value from the UI element (in your case, I guess it is drop down) and set it to the attribute 'rowCount' like this.
wdContext.currentContextElement.setRowCount(
wdContext.current<nodeElement>.set<AttributeBound toDropDown>);

How to retrieve the java object in a proxy service in osb -- Plz help

Hi all,
I have a singleton java class which runs whenever the weblogic server gets started and store the output in its object. I need to access this java object from a proxy service in osb.
We tried using java call out and retrieved that object but we couldn't know how to parse that object into XML.
We are not sure of using the java call out in osb to solve this purpose because whenever we use a java callout, that particular java code will run which is not the case of singleton class.
So kindly help us how to retrieve the java object which holds the output without running the java code every time because its already run and holding the output in its object.
Regards
Prabhu

here the doc http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1106656
but I guess you are already at the stage of getting a POJO in a first Java Callout and passing the POJO to a second Java Callout, which should then return it to OSB as a XMLObject.
My recommendation is to write a Java function which returns a XMLObject and uses a XMLCursor to populate it with the values of the POJO.
An XMLObject returned to the OSB is automatically transformed in a "XML" variable (which in reality is represented as a XMLObject in the Pipeline context)
Here some code sample:

How to populate the view object programetically

Hi all,
Is there any way to populate the records present in my backing bean. In my beacking Bean there is an array list how can i assign the array list values to the View Object.
Thanks in Advance.,
Mohan Krishna m.,

It's something like this that are you finding ?
populateViewObject(ViewObject vo, ArrayList<MyBean> arrayBean){
Ror myRow = null;
for(MyBean my : arrayBean){
myRow = vo.createRow();
myRow.setProperty("<PropertyName>", my.getPropertyName())
//Another Properties ...
vo.insertRow(myRow);
}

Replace default table sort with order by on the view object

The Jdeveloper help for af:table says:
If the underlying model is not a CollectionModel , the Table automatically examines the actual data to determine which properties are sortable. Any column that has data that implements java.lang.Comparable is sortable. This automatic support cannot be nearly as efficient as coding sorting directly into a CollectionModel (for instance, by translating the sort into an "ORDER BY" SQL clause), but is sufficient for small data sets.
I have a database table with varchar2 columns that can contain string, date or number values. So in the af:table I want to sort the columns either in string, date or number order.
I tried creating a sort listener and in that listener set the view object order by clause and execute the query, but it does not affect the row order - it is always sorted as a string. I assume that the collection is doing its sort after I do the query, and overwriting the query order. I have tried disabling the sort in the listener by setting the sortcriteria to null but it has no effect.
Can anyone suggest how to stop the default sort re-ordering the rows, or else how to code sorting directly into the CollectionModel as suggested in the help.
Hugh Nelson

By running in debug I discovered that when you click on a column heading to sort by the column values it actually sets the order by clause on the view object and executes a query. The help says that the default sorting is not as efficient as setting the order by clause - perhaps the help is out of date because default sorting does set the order by clause.
This means that you cannot do a column sort on a transient attribute. The attribute being sorted on must exist in the table/query.
The easiest solution is to override the setOrderByClause method on the view object. The string parameter is the column to order by eg "COLUMNA". If this column holds date values I can change it to something like "TO_CHAR(TO_DATE(COLUMNA,'DD-MON-YYYY'),'YYYYMMDD')". For numbers I do "LPAD(COLUMNA,10,'0')".
This works OK.

How to set Where clause in the View Object of the MessageChoice ?

Hi,
How to set Where clause in the View Object of the
MessageChoice ?
Example:
<bc4j:rootAppModuleDef name="EdEscolaCampusView1AppModule"
definition="ed00050.Ed00050Module"
releaseMode="stateful" >
<bc4j:viewObjectDef name="EdEscolaCampusView1" >
<bc4j:rowDef name="CreateEdEscolaCampusView1" autoCreate="true" >
<bc4j:propertyKey name="key" />
</bc4j:rowDef>
</bc4j:viewObjectDef>
<bc4j:viewObjectDef name="ListaTipLocalView1"
rangeSize="9999">
</bc4j:viewObjectDef>
</bc4j:rootAppModuleDef>
</bc4j:registryDef>
messageChoice declaration:
<bc4j:messageChoice name="SeqTipoLocalCampus"
attrName="SeqTipoLocalCampus"
prompt="Local do Campus">
<contents>
<bc4j:optionList attrName="SeqTipoBasico"
textAttrName="NomTipoBasico"
voName="ListaTipLocalView1"/>
</contents>
</bc4j:messageChoice>
I would like set where clause of ViewObject, with dinamic parameters (using attribute1 = :1), before populate messageChoice.
thanks...

Hi Andy,
I try set a where clause using the message:
Set where Clause parameter using UIX , but my UIX Page have 2 messageChoice's of different ViewObject's, then I need implement this Java Class:

// Executa a Query

return new EventResult(page);
The code works very well...
And, I'm sorry for my two repost's in UIX Forum about this in a few time.
Thank very much...

Issue in attaching dynamic Query to the View Object

Hi,
We are having a View Object attached to the JRAD page.
The View object is build thru as Expert mode. There is no any CDATA
SQLQUERY stored in the VO.xml file.
We are building the query dynamically and attaching it to the VO in
RUNTIME.
The code is as below
// getFcstQuery() is method used to return the dynamic query
String query = getFcstQuery();
// Setting the Query to View Object
getViewDef().setQuery(query);
setQuery(query);
The JRAD page has sorting option on 5 columns. so when a sorting is
done the data are interchanged between the clients.
For example how the query will be build id
Say for the first user the query will be as
"select ename,eno,dno from emp where eno=1 "
for the second user the query may be
"select ename,eno,dno from emp where eno=2 "
Now if both the user hit the sorting on any of the column the data is
interchagned between this both users.
Please provide solution if possible.
Thanks in advance

Hi Steve,
We are using 5 tables in building the query.
Say,
1) summary
2) transactions
3) transactions_history
4) rules
5) rules_temp
but only 2 tables are used at a time
for read only we are using
summary table
for edit only mode we are using
1) transactions and
2) rules
tables
for edit and recalculate mode we are using
1) transactions and
2) rules_temp
tables
for one more condition we are using
1) transactions_history and
2) rules
tables
From all the above combination we are getting 5 columns. All the columns are defined the above combination tables. So using the same region. based on the conditions the combination of tables will change.
Becoz of this we are building the query dynamically.
Thanks
Balamohan
