Problem in fetching row code...
Hi there,
I have a bit of a problem setting up automatic row processing. The Apex processing is causing an error, but I'm not sure what PL/SQL code is being run (obviously, I don't have access to the Apex code) and all I get is the error following:
0.03: Processing point: AFTER_HEADER
0.03: ...Process "Fetch Row from VMS2_VU_VEHICLE_DETAILS": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:VMS2_VU_VEHICLE_DETAILS:P21_ID:ID
0.05: Show ERROR page...
0.05: Performing rollback...
0.05: Processing point: AFTER_ERROR_HEADER
and then the following exception report on the page:
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
Can anyone tell me how I can diagnose the problem?
please ,
Thanks in Advance
Ahmed ,
Go to apex.oracle.com, use the Request a Workspace link, submit a request, wait for approval, then import your app into your workspace.
Create a table in your workspace schema using the SQL Workshop so that you can get the same error message when you run that form page that's giving you trouble.
When you get to that point, just tell me your workspace name and application ID.

Problem in fetching the code for the line item
Hi,
I am working on a report in which to display the values corresponding to the line item of a PO.
For, ex, if there are 3 line items 10,140,150 and their condition values such zing,zgrd,zbrd are the condition types consist of different values depending on the line item i.e. 10,140,150.
My problem is when i execute the code the data of 1st line item is correctly fetched but the rest 2 line item data is pasted as it is. only the main pricre changes and the code for zing,zbrd,zgrd remains same as it is in the first line item 10.

Why are you looping at the same internal table so many times, you could probably perform everything within one loop instead.
DATA : vspl LIKE konv-kbetr.
DATA : vspl1 LIKE konv-kbetr.
DATA : vkwert LIKE konv-kwert.
DATA: VSPL2 LIKE KONV-kbetr. "ZING COST

DATA: VSPL4 LIKE KONV-kbetr. "ZBDL COST
field-symbols <fs>.
LOOP AT item assigning <fs>.
SELECT kbetr FROM konv INTO <fs>-rate WHERE knumv = header-knumv AND kposn = item-ebelp

Also, use field-symbols and use loop at itab assigning addition so that you can directly change the contents of the table without using modify statment.

Hi
I have a table which contains one foreign key(say function_id) and I made a composite primary key in my table which is the combination of two fields (say function_id,groups)..so I dont use any automatic generated id in this table..I did not have any problem in inserting the details...But I got a problem in updating the details..i.e I want to fetch the details(group,function_id)...the problem is that I got 'no data found error' while fetching...can anyone say what condition have I to give to fetch the details....

Hello,
I have got the following problem. I have got a table with data from my database. And a dataprovider to fetch the data from my rowset. I have got a button in each row of this table where i can get details or delete the corresponding row.
But when i click delete he wont delete the row correct. After a while i realised that the always fetch the same row. I dont understand why because i took the same code as it was used in the tutorial. For control i made a variable to remember the id of the fetched row but it wont change after the first "delete". Can somebody tell me why he wont change the value?
public String l�schen_action() {
try {
RowKey rowKey = tableRowGroup1.getRowKey();
int id = getSessionBean1().getMaxappid().parseInt(applikationDataProvider.getValue("APPID", rowKey).toString(), 10);
getSessionBean1().setTemp(id);
if(rowKey != null && applikationDataProvider.canRemoveRow(rowKey)){
applikationDataProvider.removeRow(rowKey);
applikationDataProvider.commitChanges();
applikationDataProvider.refresh();
} catch (Exception e) {
log("Fehler beim L\366schen des Eintrags", e);
error("Exception deleting row: " + e);
} // end try catch
return null;
Thanks in advance for help

PROBLEM WITH NEW ROW --- PLEASE HELP
Hello,
I've had it with the framework. It's been 20 hours and counting that I am trying to insert/validate a new record.
Things just don't work as advertised.
Here's the situation:
I have an entity object with various validation rules in the validate() method.
Then I have a simple JSP page to insert new records.
At submit of button, I follow the framework's default
create new row and fill it up, with the difference
that i need to validate the row as soon as I fill it up
with data from the http request:
<jbo:OnEvent name="Create">
<jbo:Row id="newrow" datasource="ds" action="CreateInRange" >
<% try { %>
<jbo:SetAttribute dataitem="*" />
<%
newrow.validate(); //******* NOTICE HERE THAT I VALIDATE
} catch (JboException ex) {
newrow.remove();
throw ex;
} %>
</jbo:Row>
</jbo:OnEvent>
Unexpected behavior 1: If the validation fails,
newrow DOES NOT GET REMOVED!!!! I know this
since when I view data thru a data table component,
the row is there WITH THE ERROR INFORMATION set!!.
If I do a commit transaction, then the erroneous information ENDS UP IN THE DATABASE!!!!!
Unexpected behavior 2: If I do a rollback, every
call to subsequent pages results in a jsp error:
java.lang.ClassCastException: oracle.jbo.html.jsp.datatags.OnEventTag
PLEASE HELP.
Chris LambrouI have (hopefully) found a solution to my part of this problem. I was getting the ClassCastExceptions on any page with a <jbo:row> tag after doing a failed DML action. I have tested this with the delete event. (btw, I am using jdev9.0.3.3 w/ BC4J/JSP) Before what I was doing was this:
<% try { %>
<jbo:Row id="delrow" datasource="ds" rowkeyparam="jboRowKey" action="Delete" />
<% } catch (JboException jboEx) { %>
do something
<% } catch (Exception ex) { %>
uh-oh, this is bad
<% } %>
If I removed the try/catch block everything worked fine. Unfortunatlely, I need to try/catch block here. To work around the problem I changed the code to this:
<% Row rowDelete = ds.getRowFromKey(params.getParameter("jboRowKey")); %>
<% try { %>
<%
rowDelete.remove();
%>
<% } catch (JboException jboEx) { %>
do something
<% } catch (Exception ex) { %>
uh-oh, this is bad
<% } %>
The second bit of code does the same thing (but it doesn't use a bean like I think <jbo:Row> does) and it doesn't cause the ClassCastError on subsequent errors.
I really hope this helps someone else because it took me forever to get a workaround!

Problem in deleting Rows of JTable after sorting it
Hi all,
I'm getting problems in Removing Row(s) after sorting a JTable.
Please find the code snippets at this URL. Thanks for your time...
http://forum.java.sun.com/thread.jsp?forum=31&thread=459736&start=15&range=15&hilite=false&q=Hi Abhijeet,
I tried it the way you said using
wdContext.nodeBirhtday_List().nodeItab().moveFirst();
// loop backwards to avoid index troubles
for (int i = n - 1; i >= 0; --i)
current_date = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getDate();
current_month = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getMonth();
if (( current_date != date_today ) && ( current_month != month_today ))
wdContext.nodeBirhtday_List().nodeItab().removeElement(wdContext.nodeBirhtday_List().nodeItab().
getElementAt(i));
wdContext.nodeBirhtday_List().nodeItab().moveNext();
It adds records...
According to Valerys Solution, the IPrivate<CustomController> doesnt show me the required nodes. and gives me 'Unable to resolve' error.
Can you please suggest where I am going wrong

Unable to fetch row opening form on table
Hi all,
i have a page with 2 regions, a form on table for DML and a report region that lists the same table.
I am trying to create records in the form and then recall them by report row link for changes.
I cant test if all that stuff can work because i when i run the page after first time an Unable to fetch row error is raised.
After that i have to logout and login and run the page again.
I do my best to explain the problem but feel free to ask for more.
Any kind of help or suggestions are welcome.
Thanks, AlexHi,
yes this is the problem.
When i run the page the first time it seem to work fine but after editing, just edit page and run again , the error is raised and the only way out is to logout apex.
My expectation was that if i run the page setting the rowid item , that is the pk of the tabular form, the region appear with setting for insert.

Fetch Row process error in form called from report
I have an interactive report that calls a form (when user hits the edit link on a row). The form is using a fetch row process (Automatic Row Processing). The problem I have is if a user tries to hit the edit link on a row that was already deleted, I get the 'No Data Found' error. I got around it by adding a condition (exists) to the fetch row process, but that just retirns a blank recor din the form. I wanted to either make a nice error (with a validation) etc. Anybody run into this?
Bob,
The easiest thing to do would be to have the page with the interactive report submit the page and you could use a validation on that page to run the check before redirecting the user to the form with a branch. To do this, however, as the interactive report only has "link" options, you'll need to use a little javascript in the query...
Example:
SELECT id,
'<span onclick="doSubmit(''' || id || ''')">Edit</span>' AS edit
FROM TABLERegards,

How to fetch rows from PL/SQL table(Collections)
Hi,
I retrived rows from the table and stored in to table type.
Now I want fetch these rows and display on the screen. Pls guide me.
following code is my code:
DECLARE
type t1 is table of emp%rowtype index by binary_integer;
var1 t1;
v_counter number:=0;
BEGIN
select * bulk collect into var1 from emp;
for vr in var1.first..var1.last
loop
dbms_output.put_line(var1(1)); --Got an Error Here. Acually I don't Know how to fetch.
update dept set deptno=var1.deptno --Here also Error occured.
end loop;
END;Fetching rows to display them is a task for the client tool. You need to define a ref cursor therefore.
If you just want to play around, here we go
SQL> DECLARE
2 type t1 is table of emp%rowtype index by binary_integer;
3 var1 t1;
4 v_counter number:=0;

Problem with front row, please help!
I got a year old MBP 15" which I updated to leopard, and it works generally fine, except for the fact that when using front row and leaving it playing music for about 5 minutes idle, it freezes, goes to blank screen, but still plays the playlist it was set on, but when I use the remote control, or press keys, it keeps frozen, the only way to quit is to force power off.
Please help me, as I really like Front Row and my MBP is my hub for playing music in reunions.

netui-data:pager action to dynamically fetch rows
Hi,
How can I configure a data grid pager to dynamically fetch new rows when a user swap pages through the pager?
I know I can fetch all my rows to a collection / array before rendering the datagrid and set the pager to iterate over it like this:
[Controller]
private List<Ride> rides;
public List<Ride> getRides() {
return rides;
[Action]
rides = rideDBControl.getAllRides(); // huge amount of data
return forward;
[JSP]
<div style="border-width:2px;"><netui-data:dataGrid name="currentRidesGrid" dataSource="pageFlow.rides">
<netui-data:configurePager pagerFormat="prevNext" pageSize="${pageSize}" />
<netui-data:header>
<netui-data:headerCell headerText="Name" />
<netui-data:headerCell headerText="Description" />
</netui-data:header>
<netui-data:rows>
<netui-data:spanCell value="${container.item.name}" style="background-color: #f0f0f0;font-size:14pt;">
</netui-data:spanCell>
<netui-data:spanCell value="${container.item.description}">
</netui-data:spanCell>
</netui-data:rows>
</netui-data:dataGrid></div>
But how can I make the pager call a method to update the contents of the collection "rides" according to the current selected page and page size? And how can I obtain the current page and page size inside that method?
I want to paginate queries that may return a huge amount of data (1m + rows), so, fetching all rows at once is impracticable. What I want to do is propagate the current page and page size from the pager to a method that will update the current collection according to a query such as:
Select X, Y, Z
From Table
Where ...
And ROWNUM BETWEEN page * pageSize AND (page + 1) * pageSize
Can anyone help a noob?For further reference I've found the answer by myself.
To dynamically fetch rows you need to modify the <netui-data:configurePager> tag and include both a pageAction and partialDataSet attributes, e.g.:
<netui-data:configurePager pagerFormat="prevNext" pageSize="${pageSize}" pageAction="pagination" partialDataSet="true" />
Within the pagination action you can obtain the current row and page size from a PagerModel object. You can then update the dataSource (just remember to call the setDataSetSize providing the length of the full dataset so that the pager displays the correct amount of pages), e.g.:
@Jpf.Action(forwards = { @Jpf.Forward(name = "success", navigateTo = Jpf.NavigateTo.currentPage) })
public Forward pagination() {
DataGridStateFactory dataGridStateFactory = DataGridStateFactory
.getInstance(getRequest());
// Gets the pagerModel object for the grid
PagerModel pagerModel = dataGridStateFactory.getDataGridState(
"currentRidesGrid").getPagerModel();
// => Code to get the entire dataSource size <=
pagerModel.setDataSetSize(dataSourceSize);
// Obtain the first row and page size from the model
int firstRow = pagerModel.getRow();
int pageSize = pagerModel.getPageSize();
// => Code to fetch the rows to be displayed <=
rides = pageRides;
Forward forward = new Forward("success");
return forward;
I hope this helps.

Problems with multiple row operations in a dataTable
Dear fellows,
I have a strange problem, i want to do multiple row deletion in a dataTable. Can any one tell me a better way to do it. Because the way i am doing it, it is causing me strange problems. In some places it start working and in some it dont.
The way i am doing it, it has the following code:
<h:form>
<h:dataTable id="list" value="#{availableRoomsList}" var="RoomTypes" >
<h:column>
<f:facet name="header">
<h:outputText value="Select"/>
</f:facet>
<h:selectBooleanCheckbox value="#{roomSelection[RoomTypes]}" >
</h:selectBooleanCheckbox>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Available Date"/>
</f:facet>
<h:outputText value="#{RoomTypes.availableDate}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Available Rooms"/>
</f:facet>
<h:outputText value="#{RoomTypes.noOfRooms}"/>
</h:column>
</h:dataTable>
<h:commandButton value="delete Selected Rooms" action="#{RoomResvAction.deleteRooms}" />
</h:form>Now the back end code that i am using is as follows:
private List<HotelRoomTypes> availableRoomsList;
Map<HotelRoomTypes, Boolean> roomSelection = new HashMap<HotelRoomTypes, Boolean>();
public String deleteRoom(){
System.out.println("In the delete selection method aad.");
try{
for (HotelRoomTypes item: availableRoomsList) {
Boolean selected = roomSelection.get(item);
if (selected!=null && selected) {
roomSelection.put(item, false);
//deleteRoom(item);
}catch(Exception e){
//e.printStackTrace();
return null;
}The problem with the JSF code is when i click the command button it do not calls the associated action method with it. i dont know what is the problem with the code.
And as far as the backend code is concern it should work fine.
can anybody help me on this matter.thanks BalusC ,
I will see this example and let you know, thanx for the help.
but also please try and see my code and tell me what is wrong in it. because at some places it works and at some it simply dont . dont know why?
