Problems on deleting rows in UIX pages

Hi,
I am new on using BC4J, Struts and uiXML and I am having some problems on it. I have tried to make a simple create/update/delete web application.
First, I have created a DataAction which PageForward displays a table with data from a view object. This page allows the user to select a row and request its deletion by clicking on a submit button.
The event triggered by the submit button calls a DataAction that displays another PageForward, composed by a read-only form, that asks for confirmation. If the user confirms, a DataAction that performs the Delete method from the view is called and the deletion is successful.
A problem occurs when I change the readonly property of the fields of the confirmation form: the row deleted is not the selected, but a random one.
I would like to know why the readonly property of the fields change the Delete method behavior. Also, an example of a simple create/update/delete struts page flow would be appreciated.
Thanks in advance.
Verner.

Verner,
Are you using JDeveloper 10g Preview or JDeveloper 9i v9.0.3?
I'm not sure what problem you are having, but I just tried to reproduce your application by doing the following in JDeveloper 10g Preview:
1) Created new business components.
2) Created a new struts-config.xml.
3) Added to the Struts config (using the page flow modeler):
3.a) Browse data action and page forward to browse.uix
3.b) Confirm data action and page forward to confirm.uix
3.c) Delete data action.
3.d) Link from browse action to confirm action for outcome "delete".
3.e) Link from confirm action to delete action for outcome "delete".
3.f) Link from confirm action to browse action for outcome "cancel".
3.g) Link from delete action to browse action for outcome "success".
4) Then I made the delete action do the deletion by dragging the Delete operation from my data control onto the Delete data action in the page flow.
5) Then I created my UI pages.
browse.uix just has a read-only table created via the Data Control palette and then a delete button that fires the "delete" event when clicked. The delete handler returns the delete outcome.
confirm.uix has a read-only form also dragged from the Data Control palette for the same data control. There's a delete and a cancel button, each of which fire an event of the same name that returns an outcome of the same name.
When I run browseDataAction, I see my table. When I click "Delete", I see the read-only form with the details for the selected row. Clicking "Delete" from the confirmation page removes the same row I saw in the confirmation page, then goes back to the browse page showing the same range but with the given row removed.
If you continue to see a problem, what exactly is wrong? It should be the case that (A) the row selected in the table, (B) the row whose details are shown in the confirmation page, and (C) the row that gets deleted are the same row. If it's not the case that A = B = C, please give more details about what values of these three rows you are seeing. Is A=B but not =C? Or is B=C but not =A?
Hope this helps,

     //     loop backwards to avoid index troubles
     for (int i = n - 1; i >= 0; --i)

Javascript problems using HttpUnit while testing UIX pages

Hello JDeveloper Team
Need urgent help about testing my web pages written in UIX. I tried to use HttpUnit but I got Javascript errors. What is wrong with it ?
I also used HtmlUnit. It works well but writing code to check the html page that is produced from a UIX is a stomachache. I mean all the ids , names of components are so absurd words. A submit button for example is a link with an image inside it but has no name or id. So there is no way to reach it with a method of HtmlUnit library.
Can you please advice me a methodology to test my uix pages? Or is there any tool or application for this purpose ? It could be licensed . My company needs such a tool. I also tried AppPerfect but it does not support UIX.
I need your valuable opinions. An answer that is quick would be appreciated.
Thanks

if you want an ID in the html, you can set it in the UIX file and it will appear
in the html

Problem in deleting row from database in table component

Hi,
I have a table component that its content change by diffrent links.
in this table i have a hyperlink in each row to deleting that row from dataBase.
so i must get the current row .
i do it like this:
define a rowset in the page that have a delete query :
delete from response where responseID=?
in action of delete hyperlink ,i have:
Integer responseId=(Integer)responseDataProvider.
getValue("#{currentRow.value['responseID']}") ;
getSessionBean1().getResponseRowSet().setObject(1,responseId);
getSessionBean1().getResponseRowSet().execute();
but in first line occure a exception:
illigalArgument #{currentRow.value['responseID']}
thanks.

by using data table
first you should get current record (row that recived action)
then delete it by using data provider.
I do not think that you could execute delete statement using rowSets because they just can provide Select statements.
btw , following code will retrive clicked row from data table and
delete that row
try {
RowKey rk = getTableRowGroup1().getRowKey();
if (rk != null) {
testDataProvider.removeRow(rk);
testDataProvider.commitChanges();
} catch (Exception ex) {
log("ErrorDescription", ex);
error(ex.getMessage());

Problems to delete Rows

Hi,
i want to delete all rows in a table which will be automaticlly updatet in a thread. the problem is that i get somtimes the message 9>=9 or 8>=3. did somebody know what that means ?!?

it means the row index that you are trying to remove doesnt exist.
9>=9 means that you are trying to remove row index 9 in a table that has only 9 itmes (remember its zero based)
there's probably something dodgy with you remove code.
off the top of my head try looping through with (rowcount - 1)

Problem in Delete Row

Hai To All,
         Iam using PL 05 i have enable DeleteRow option. If i click the deleterow the row is deleted but after saving the entry there is null value in database. for example if i have 2 row in the matrix if i delete last row the content is deleted after that iam saving the matrix. In the database i have 2 rows one with content and other with null value..
Whts the soultion of this....
Does anyone have idea reply me....
Regards,
Anitha

Hi Anitha,
For the delete option, you need to right a small function if its going to be ur own form.
Try using the following code...
Private Sub DeleteRow()
        Dim oDBDSource As SAPbouiCOM.DBDataSource
        Dim Count As Integer
        Dim oMatrix As SAPbouiCOM.Matrix
        Try
            oDBDSource = objForm.DataSources.DBDataSources.Item("@TableName")
            oMatrix = objForm.Items.Item("3").Specific
            oMatrix.FlushToDataSource()
            oMatrix.DeleteRow(strRow)
            objForm.Update()
            'objForm.DataSources.DBDataSources.Item("@TableName").RemoveRecord(strRow - 1)
            oDBDSource.Clear()
            oMatrix.FlushToDataSource()
            oMatrix.LoadFromDataSource()
            For Count = 1 To oDBDSource.Size - 1
                oDBDSource.SetValue("Code", Count - 1, Count)
            Next
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
Hope this helps.

Problem in deleting rows

Hi experts,
in the following method. I am deleting the records from the BAPI output table where the date and month do not correspond to todays date and current month.
When I execute the BAPI for one employee it gives me the correct output. ie one record. But when I execute it for all the employees and when I use the following code. It gives me a blank output.
public void wdDoInit()
    //@@begin wdDoInit()
    int date_today, current_date;
    int month_today, current_month;
    char date_satisfied, month_satisfied;
    Date date = new Date(System.currentTimeMillis());
    date_today = date.getDate();
    month_today = date.getMonth();
     int n = wdContext.nodeBirhtday_List().nodeItab().size();
     int leadSelected = wdContext.nodeBirhtday_List().nodeItab().getLeadSelection();
     //     loop backwards to avoid index troubles

Problem with UIX Pages in sub folders

I want to group my UIX pages into sub folders to maked definition of security constraints more convenient.
The New UIX Page wizard doesn't allow creation into a sub folder so I have created a blank page and then renamed it into a subfolder using File>>Rename menu option. However, now when I drag Data Control bindings onto the page they fail to bind properly. (No data appears when I run the page.)
Is there a fundamental problem with placing UIX pages into sub folders? Is it something I shouldn't do? Requiring a flat file structure seems an onerous restriction!
Thanks
Matthew

yes. this is a known problem when you are running UIX pages and not struts dataactions.
For the model bindings to work, you currently have to keep
all your uix pages in the top level directory.
However, if you use the struts-pageflow with UIX pages, then you can keep you UIX pages where ever you want.

Refreshing an UIX page

Does anybody know how to explicitly for an refresh on a UIX page.
The problem that I have now is that only after I some where did a rollback, the page is displayed correctly.
Before the rollback, the page shows one table updated and one table still in the former state, which was before I added an extra row.
Thanks in advance,
Gideon

So again I want to bring this to your attention, because I believe I am not the only one with this problem.
I have a UIX page with two tables. I created the funtionality to add a row from table2 to table1.
The problem is that after I did a Commit and the row has been added to table1 and removed from table2, only table1 is updated and table2 is still in the former state.
At least it is in the former state on the screen.
In the database the change has already been made.
Only after I did a "rollback" somewhere, will the UIX page display correctly.
Does anybody know how to solve this problem and do a proper refresh of the tables in UIX?
Any help appreciated,
Gideon

Javascript Error with UIX Page

Hi all,
I am using JHeadstart 10.1.2.2.32 with JDeveloper 10.1.2.1.0 to develop UIX pages. I have run into the following problem with one of my UIX pages. We have a page with a table view which uses sortable headers. In certain situations when using the sortable headers in IE 6.0.2900.2180, a javascript error appears. This does not occur using Firefox.
It says:
Line: 2894
Char: 1
Error: 'type' is null or not an object
Code: 0
URL: (the URL of the page)
I have figured out that the error is occuring in the Common2_2_20.js file on the following line, which is part of the function _multivalidate:
var a7 = a6.type; The error only occurs in the following situation. If the user has just logged into the system and certain rows in the table are read-only and others are editable. If you click on any of the sortable headers, it will sort fine the first time. However, if you click on the sortable header again, the javascript error appears. It only happens if you click on the sortable headers twice in a row.
I have tried taking out the line of code, but then I can not sort the headers at all.
I read in the forum that the error can occur because of the way IE handles the compression of javascript files. We changed the setting on the app server to not compress javascript files. I then undeployed and redeployed the application. However the same error is still occuring.
If you need any more information, please let me know. Thanks in advance.
Susan

We found out that we had a custom script on the page that was interfering with script in the Common2_2_20.js. By moving the script to the end of our page, it solved our problem.

How to delete row by row comparing to first collumn?

Hello!
I have a problem - I need to delete row by row , but the problem is, that I know that first COLUMN of any table is a PK.
To retrieve COLUMN NAME I use:
SELECT column_name, table_name FROM USER_TAB_COLUMNS WHERE column_id = 1 and table_name = c1.tmp_table_name;
But this somehow doesn't work.
Below you can see my script (not worked for now):
declare
xxx varchar2(100);
begin
for c1 in (select table_name, tmp_table_name from tmp_tables) loop
EXECUTE IMMEDIATE
' SELECT column_name into '|| xxx ||' FROM USER_TAB_COLUMNS WHERE column_id = 1 and table_name = ' ||''''||c1.tmp_table_name||'''';
execute immediate
'begin
for c2 in (select * from '|| c1.tmp_table_name || ') loop begin
insert into '|| c1.table_name || ' values c2; delete from '|| c1.tmp_table_name || ' where ' || xxx ||' = c2.'||xxx ||'; exception when others then null; end; end loop; end;';
end loop;
end;
P.S. Inserts work perfect. I have a problem with delete rows that are in c1.table_name, from c1.tmp_table_name (this two tables have the same structure, PK, always), because I have different column names in another tables tables that are PK. (for example: K, ID, NS and so on) please help me to write correct script.
For example for first fetched row it will be like:
begin
for c1 in (select table_name, tmp_table_name from tmp_tables) loop
execute immediate
'begin for c2 in (select * from '|| c1.tmp_table_name || ') loop begin
insert into '|| c1.table_name || ' values c2; delete from '|| c1.tmp_table_name ||' where K = c2.K; exception when others then null; end; end loop; end;';
end loop;
end;
That script works perfect. But I have many others tables with different PK - not K.

Problem with multi row delete

Hi, I'm new in apex and I tried to build master detail report on some view. Everything is cool but "delete checked" doesn't work.
"ORA-20001: Error in multi row delete operation: row= , ORA-06502: PL/SQL: numeric or value error: NULL index table key value,"
the problem is that I don't know what is wrong :), I have a special trigger "instead of delete on MY_VIEW", but in this error problem is not explained.
Anybody knows what can be wrong? It is probably a problem with trigger or multi row doesn't work with views? I couldn't find how MRD knows what kind of statement use to delete rows so I don't know if the statement that program used is correct. In debug it lokks that:
0.32: ...Do not run process "ApplyMRU", process point=AFTER_SUBMIT, condition type=REQUEST_IN_CONDITION, when button pressed=
0.32: ...Process "ApplyMRD": MULTI_ROW_DELETE (AFTER_SUBMIT) #OWNER#:MY_VIEW:ITEM1:ITEM2
0.33: Show ERROR page...
0.33: Performing rollback...
thanks for any help
//sorry for english mistakes
edit: it doesn't matter if I use in trigger delete from ... where item1=:OLD.item1 ; or if I use item1=:P4_item1 (which actually saves correct values)
Edited by: user5931224 on 2009-06-13 08:55

I realised that this is not a problem with trigger, I changed trigger to "NULL;" and problem is the same. Maybe sb used master detail on view not only on tables and know what can be wrong in this situation?

Problem in deleting a row

hi,
I have a table with set of values. added three buttons below that in table. add row, delete row, save.
if I delete the row and save and if i come again to that application still that deleted row remains. what might be the problem?

you can use flag in your internal table,
when you press delete button after selecting the particular row, set the flag for this entry in itab.
now in save event loop through the table checking flag, and delete enteries. now bind the table again by the itab.
you can do the same thing in delete button event also,
if not solved, please explain more

Actually i'm selecting a cell of a row, then hitting the delete button.
So the model is deleting the information, but i'm not able to c the fresh data in table( especially when the last cell of last row is selectd and hit the delete button, i am getting lots of exception)

Hi,
I've got the solution for it. As when the cursor is in cell of
a row and hit the delete button, the data in that cell is not saved,
So i'm trying to save the data first into the model then firing the action event by doing this ..
jButton2.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
// If a button press is the trigger to leave a JTable cell and save the data in model
if(jTable1.isEditing() ){
String text=((javax.swing.text.JTextComponent)jTable1.getEditorComponent()).getText();
jTable1.setValueAt(text,jTable1.getSelectedRow(),jTable1.getSelectedColumn()) ;
jTable1.getCellEditor().cancelCellEditing();
// HERE DO THE DELETE ROW OPERATION
