Adding new rows at run time in alv oops

HI ALL,
I have a created an editable alv report in oops. Now i have to add a new row having similar values as the previous row at run time when a custom button is clicked in the output and after entering some values in the new row and pressing the database must be updated and also the internal table at run time itself.
for example let us suppose i have the following row in the alv output.
MATNR                          DESCRIPTION                             NAME                             DATE
001                                 TEST                                        MATRIKS                      10092001
NOW if we click the custom button added on the alv toolbar, it should a new row at the run time similar to previous row as shown below
MATNR                          DESCRIPTION                             NAME                             DATE
001                                 TEST                                        MATRIKS                      10092001
001                                 TEST                                        MATRIKS                      10092001 -> NEW ROW.
can we do it in alv oops? pls let me know the soln or any helpful links
thanks

Hi John,
I dont think, you can find any method for that,
one way what I can suggest is
Get the selected row index.
Insert the blank row in your internal table at this index
Refresh the container.
Hope this will help.
Thanks,

but the entire row is coming blank, not able to get the default values in new row
how can i refresh the grid so that default values come on adding new row.

Hi Surabhi,
Use this in Interactive section even if you are doing simple ALV.
DATA:
lv_ref_grid TYPE REF TO cl_gui_alv_grid.
CLEAR : gv_tcode.
*-- to ensure that only new processed data is displayed
IF lv_ref_grid IS INITIAL.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
e_grid = lv_ref_grid.
ENDIF.
IF NOT lv_ref_grid IS INITIAL.
CALL METHOD lv_ref_grid->check_changed_data.
ENDIF.
THis will solve your problem.

Can iOS Numbers copy formulas when adding new rows?

iOS Numbers table add row is not copying previous cell formulas. Is this supported or not?
I have a table with lots of columns and all of them have formulas. When I click at the lower left of the table to add a row, none of the new cells have the formulas. I have to manually go through every column and copy the formulas to the new row.
This is not very practical if you're planning to use Numbers on the go with an iPad. In my case, I have to quickly get a new row ready as needed. I was hoping there is a preference setting somewhere like "copy formulas when adding new row".

I had the same issue with the added twist that I wanted to reference the created cells in formulas in other sheets. This is what works for me:
I use a form to enter data. The referenced sheet is set up like this:
1     Name     Date     ServPayment    SalesPayment     Total
2     Week1                                                                 =sum (ServPayment,SalesPayment)
3                                                                                =sum (ServPayment,SalesPayment)
4     TotWeek1                                                            =sum (Total2,Total3)
"Total" sums the 2 Payments, TotWeek1 sums the totals.
In the entry form I never add data to the empty line. In this example, I would start at "Week1" and tap the "+" to add a new form. This creates the line in the referenced sheet with my formulas. As I continue, I always start at the last entry I have made and tap "+".
When I create a line that does not have the formula on either side, I do not get the formula.
Hope this helps.

Null Pointer Exception When Adding New Row on Table

Hello JheadStart Team
I have used detail group with table layout , when I am clicking on AddRow button on detail table , I encounter NulllPointer Exception . I have traced the code and fount that in JhsCollectionModel when adding new row following
condition occurs :
DCIteratorBinding ib = getRangeBinding().getIteratorBinding();
int rangeSize = ib.getRangeSize();
int rowsInRange = ib.getAllRowsInRange().length;
because getAllRowsInRange is Null then the error raise.
My JheadStart ver is 10.1.3.3.85 .
Detail Group with table layout setting is :
Use Table range=true
Show New Row at top=true
New Rows:empty
Show Add New Row Button :true
Regards

Given the build you are using, I assume you are an Oracle employee.
Is this correct? if so, please post your question to the [email protected] mailing list.

EDIT method doesn't work after adding new row

I would like to start editing after adding new row into TableView.
I copied example from Oracle website: [Using JavaFX UI Controls - 13 Table View|http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#CJAGDAHE]. Then I put additional button for adding new row and define action for the button.
    final Button addButton = new Button("Add");
    addButton.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent arg0) {
            Person p = new Person("", "", "");
            table.getItems().add(p);
            table.getSelectionModel().select(p);
            table.edit(table.getSelectionModel().getSelectedIndex(), table.getColumns().get(2));
    });In result I can see selected new row but the table doesn't start edditing in the third column.
I have similar method for editing existing rows and it works properly.
    final Button editButton = new Button("Edit");
    editButton.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent arg0) {
            table.edit(table.getSelectionModel().getSelectedIndex(), table.getColumns().get(2));
    });Could you help me what I do wrong?

Try wrapping the setCaretPosition(...) method in a SwingUtilities.invokeLater(...)
caret=outputArea.getDocument().getText(0,outputArea.getDocument().getLength()).length();Should be:
caret = outputArea.getDocument().getLength();

Dynamically adding new rows and columns

i want to have a button on my jsp page which shud add new rows dynamically. and same one for columns.
how do i calculate the values across the rows on the forms
I'm new to JSP. Please point me in the right direction...any tutorials or code will be helpful.
thanks

Well its a good question actually and the most needed one.
Say 4 example u need a screen which should accepts the employee details in one screen
and the user should be able to enter all the employee details in one screen and he should
have a flexibility to change the previous details too.
So 4 that u need to know 2 things:
1) Using of JspBeans
2) Using Vector
I will give u a brief idea:
So the bean is just a container been which has the methods say
setEmployeeName(.....)
getEmployeeName()
So the basic logic is, the naming of html form elements and displaying multiple rows of elements.
Say 4 eg, empname -> <input type=text name=empname<%= count%> value=<%= ....%>>
So u should run the loop the size of ur vector times and every time u add a vector u should save all
the data using same logic in ur vector and thatz it once u commit get all the values from the vector.
Try this u will definitely get it,
all da best,
kiran

Adding a button at run time

I know that you can add components at run time (I've done it with a tree for instance) but how do you link a run time added component with an action handler?
For example, when you use the designer, you just double click on a button to get an action handler built that automatically gets called when the application is deployed and that button is clicked. Well, when you add a button at run time, you have no way of doing this.
Just how do you link a dynamic button to an action handler then?
Thanks

Hi,
I generate a table at runtime and also bind it to a dataprovider at runtime and display the records in a table. It works find and I have no problem with that.
I am trying to add a new column with the button in them, i generate the buttons at runtime. Even this works fine. Along with the data in the table i have the last column with all buttons.
I am having problem binding the method to the button at runtime. My code is something like this...
     for (int i = 0; i <= numOfCols ; i++) {
          //add the delete button as the first column
          if( i == 0 ){
          TableColumn column = new TableColumn();
          column.setHeaderText("Delete");
          Button st = new Button();
          st.setText("Del");
          st.setId("del");
          MethodBinding mb = (MethodBinding) context.getApplication().createMethodBinding("#{Page.delete_action}", null);
          st.setAction(mb);
          column.getChildren().add(st);
          getTableRowGroup1().getChildren().add(column);
          } else{
          TableColumn column = new TableColumn();
          column.setHeaderText(rsm.getColumnLabel(i));
          log("rsm.getColumnLabel("+i+"): "+rsm.getColumnLabel(i));
          column.setNoWrap(true);
          column.setSort(rsm.getColumnName(i));
          ValueBinding vb = app.createValueBinding("#{currentRow.value['" + rsm.getColumnName(i) + "']}");
          StaticText st = new StaticText();
          st.setValueBinding("text", vb);
          column.getChildren().add(st);
          getTableRowGroup1().getChildren().add(column);
public String delete_action() {
log("Inside delete_action().");
return null;
The method delete_action() is not called at all.
It would be appreciated if someone could help me with this problem of mine.
Thanks,
Adi.

Adding new row to the reports list page

How can I add a new report row in the reports list of the reports tab.
Ex: a new row to the report "users by Date of Join report" is to be added
How can we add Please help me out in this

I am facing the same problem!

Try adding an empty row containing a null value for the String instead of the empty String.camickr, it will not help, the DefaultRowSorter in the "*+compare(int model1, int model2)+*" method return -1 if the first value is null and 1 if the sacond value is null. and incase of DESCENDING it mult by -1.
                // Treat nulls as < then non-null
                if (v1 == null) {
                    if (v2 == null) {

                    result *= -1;
                }And this is the real problem!
The empty line is sorted as the smallest value and incase of DESCENDING it will be the first line (because of the mult by -1).
We could have overide it and incase of the empty row(usualy the last row) do not mult by -1 in DESCENDING mode.
But the problem is that the "+*compare*+" method and it's caller "*+Row+*" inner class are private :-(
It is not wise to do it but we can do like kmp83 wrote:

Insert new page at run time to pull in images

Hello ,
I'm using Adobe LC Designer 8.2, and wondering if there is a way to insert a new page - not in design view but at run time since I have a dynamic plot as image (jpg) to bring into a form (1 image per page). How would l load the image in & create those pages for these plots - it's going to be different amount of images/plot each time when the form run. I know that I have to use script some how, but I'm new at this. Greatly appreciate all the help!
Thanks,
Trang

One idea would be.....housing the image alone in a subform and set the subform to use "Top of the next Page" under "Object>>Pagination>>Place:". Also you may have to play with "Object>>Pagination>>After:" option to get things in your favor.

Adding new row in matrix

Dear all,
I press right-click on Journal Entry and select "Cancel" function.
SAP B1 creates a new journal entry with inverted rows registration.
Now, I added a new button in this form.
When I press the button, I need to add a new empty row in the matrix.
I use this command:
oJEMatrix.AddRow()
I also used this command:
oJEMatrix.AddRow(1, 1)
but what I obtain is a new row with the same values of the first row (it seems a duplication of the first row).
The new row-index (first left column) in the matrix has the value "1" as the first original row.
How can I add a new empty row in this matrix and refresh the matrix to update the index of each row?
Best regards
Emanuele

I found the error:
I was trying to set Credit > 0 and Debit > 0 on the same row.
But now I have a nother issue with matrix.
See image below...
After populating the matrix, the rows index are incorrect. How can refresh the matrix to recalculate the correct row number in the first column?
Best regards
Emanuele

Tabular form - adding new row

Hi,
I have a very simple table (5 rows, 1 of which is the primary key), and want to update the table using a tabular form. On initial display, the primary key column is protected (cannot be changed) which is ok for DELETE and UPDATE options, but when I come to ADD A NEW ROW, the new row has NULL defaulted as the primary key value, and will not let me update it !!
Does anyone know how I can leave the primary key column protected when UPDATING or DELETING, but allow a value to be entered when ADDING A NEW ROW ?
thanks

Andy,
Just made the following changes (to remove NARR1_CODE_DISPLAY and show and edit NARR1_CODE):
select
"NARR1_CODE",
--"NARR1_CODE" NARR1_CODE_DISPLAY,
"NARR1_LOWER_LIMIT",
"NARR1_UPPER_LIMIT",
"NARR1_RMP_MIDPOINT_1",
"NARR1_RMP_MIDPOINT_2"
from "#OWNER#"."DQ_PD_TRANS_DIST_BAND_NARR1"
where the column NARR1_CODE is my primary id, and in the report attributes, NARR1_CODE is now editable and shown as a "text field" . NARR1_CODE_DISPLAY has been removed.
However, when I go into my form screen, although the NARR1_CODE field is now editable, when I click ADD NEW ROW, enter the details for a new row, check the box alongside the new row and click SUBMIT, I get the following error message :
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "A884FA378C851786DDFE3A33709CB23C", item checksum = "F6395FDACE39D98E784F85C19D960620"., update "GRD_DD10_OWNER"."DQ_PD_TRANS_DIST_BAND_NARR1" set "NARR1_CODE" = :b1, "NARR1_LOWER_LIMIT" = :b2, "NARR1_UPPER_LIMIT" = :b3, "NARR1_RMP_MIDPOINT_1" = :b4, "NARR1_RMP_MIDPOINT_2" = :b5
sorry about this !

Adding DVM values at run time

Hi,
I am trying to adding domain values to DVM at run time,
it is getting added to DVM at that movement ,bt
when i redeploy the service I am not able to see the changes.
so help required regarding this

Hello
That is the solution to his problem, by the sounds of it when he redploys his code he gets the old values (the one in his code) if he migrates it to the MDS when he redeploys it won't change. This will seperate his deployment from run time configuration values which is a good idea.

Adding new row at top of tabular form In APEX 4.0

I havea tabular form and when addrow() it is adding at bottom of the existing rows. Is there a way I can add new row at the top of the rows?
Thanks.
Edited by: Badari on Oct 19, 2011 12:07 PM

Hi Raj,
I'm trying to implement your solution to add the empty row of a tabular report to the top of the page but I can't get it to work. I've identified two errors in your code, namely
1) semi-colon after mytable.moveRow(mytable.rows.length-2,1) is missing
2) You say to use "ABC_REPORT" as the region id but you use "report_ABC_REPORT" in the code.
I've fixed these but still I cannot get it to work.
Could you check the code again and see if there are any other errors that we may have missed.
thanks in advance
PaulP
<script language="JavaScript" type="text/javascript">
function addTop()
addRow();
var mytable=document.getElementById("report_ABC_REPORT");
mytable.moveRow(mytable.rows.length-2,1) // depending on the report template selected use either length-2 or length-1
</script>

Adding A row to a non editable ALV in ABAP Webdybpro

I have an ALV thats currently non editable. My requirement is that, when a User clicks on an Insert Row button, then a new row has to be inserted in the ALV and this row alone should become completley editable. Is there any means of doing this. I am aware of some standard editable buttons (such as Insert Row, Delete row etc) but somehow this does not meet my requirement as 1.I dont need some standard buttons such as Check and 2. The whole ALV has to be editable for these buttons to work.

There are options such as set_insert_row_allowed set_delete_row_allowed etc that lets you do this. And to the editable part of the questions, those rows can be bound to another attribute in a context and as per the needs that rows can be made editable or not.
