Add/Delete Rows problem

I'm having a problem with the add row and delete row for my table. I have a table set up with the add row button in the header, and the delete row button in the first cell of the row beneath the header. I have it set so that the initial count of the row is 2. My problem is if the user adds several rows with data, and save the form. When that user goes back into the same form later, it keeps the several rows that the user entered, which is fine, but then it automatically adds 3 more blank rows to the table, which I don't want. I don't understand why it is doing this. Does anyone have a clue to why this is happening?
Thanks
Connie

Hi Connie,

Add/delete row in JTable

I went through the tutorial of JDK about how to programming JTable, i can NOT find a way to add/delete row into/from JTable.
I immagine it would be a difficult task because the data set it takes 'Object data[][]' is NOT dynamically grow/shrinkble.
Can we make it take ArrayList[] as input dataset so that the dataset can dynamically grow/shrink?
Any other way around to add/delete row?
THANKS for your consideration.

You have to write your own TableModel like extending AbstractTableModel. In that class add custom methods to add and remove rows. From those methods call fireTableRowsDeleted(..) and fireTableRowsInserted(..) to update UI.

My add/delete row function is unselectable. How do I fix this?

For no reason that I can guess I am unable to add or delete rows. That little circle icon with the two horizontal dashes is gone and when I click on a numbered row the 'add/delete row' choices are grayed out, unelectable. My spreadsheet needs are VERY basic so I'm at a loss for what has happened because I've been using this file. It WAS working like it should, but now it's not and I don't know if I clicked something OFF or what. I am not new to a Mac, so I'm not a newbie with this stuff. Any ideas??????

Try deactivating any filter you have set on the table.

JTable & AbstractTableModel(Delete row problem)

Hi!!
I have used AbstractTableModel in my JTable.In case of multiple rows, i want to delete rows from interface as well as from database. As removeRow method is absent in AbstractTableModel.so DefaultTableModel has been used by casting but CastClassException throws. Here is Partial code(tried in many ways).Plz help me to solve the problem.
void jButtonCancel_actionPerformed(ActionEvent e) {
try{
jTable1.setModel(myModel); //jtable is object of JTable and myModel is of Abstract TableModel
DefaultTableModel model=((DefaultTableModel)jTable1.getModel());
int row=jTable1.getSelectedRow();
if(row>=0){
model.removeRow();
jTable1.revalidate();
model.fireTableDataChanged();
System.out.println("Rows Delete");
catch(Exception sq){
sq.printStackTrace();
sq.getMessage();

Hmm...
A bit of studying java awaits you.
Anyway.
Your class:
public class MyModel extends AbstractTableModel
// Do various sorts of coding here
}Is not an instance of DefaultTableModel, so, if you try to cast your model to a DefaultTableModel it will throw an exception since the conversion is impossible.
Recomended solution:
Add a remove method for your class MyModel that does the following:
public void removeRow(int row)
// data removed
// fire removed data event
}Then instead of casting to DefaultTableModel, cast it to 'MyModel' and call the method 'removeRow'.
When it comes to inheritance and casting you can always cast an object to any of it's superclasses or any of the interfaces it supplies or it's superclasses suppplies. You can not cast an object to a instance of which it has no relation with.
In you example, your table model class extends the abstract table model but it does not extend the DefaultTableModel. An instance of your class can be casted to AbstractTableModel and so can an DefaultTableModel because they are both subclasses from AbstractTableModel. They can also be casted to TableModel since all of these implement the interface needed to fullfill TableModel's specification.
If you cast a DefaultTableModel instance to TableModel you can not try to cast it upwards to something the instance wasn't from the beginning.
Example:
DefaultTableModel dtm = new DefaultTableModel();
// When you do casting uppwards, there is no need for paranthesis
TableModel tm = dtm;
// You can easily later on cast this back to what is what or to any step
// in between
DefaultTableModel stillSameModel = (DefaultTableModel)tm;
// You can not however cast to something the instance never was
// Row below will cause an compile error:
JComboBox jb = (JComboBox)dtm;
// This since JComboBox can never be an superclass to the DefaultModel
// More dangerous errors that can't be catched until runtime is the
// one you made. Ie: I do what could be an valid cast
MyModel mm = (MyModel)tm;
// Since MyModel is an TableModel and tm refers to an TableModel,
// this casting is approved by the compiler.
// It will on the other hand throw an ClassCastException when run since
// the variable tm contains an instance of DefaultTableModel which
// is not an MyModel instance.Recomended that you read up on inheritance and basic OO.

How to add/delete rows on the form without saving data

I am new to apex
I am working on project and need some help on creating a form
my requirment is to save a request that has multiple questions.
i have a request form with multiple regions
On one of the region that takes questions, I want to create a tabular form such that i can add/delete/update row without hitting database and enter multiple questions
each row is one question.
Apex has the default functionality of having a tabular form linked to a table that onload shows the data from that table and also on click of add or delete hits the data base to save the data.
However i want to load a form that does not show any data if its a new request and click of add/delete should not update the databse. It should just add/delete a row on the form
so user logs in and can create a request that has multiple questions
finally want to submit the form and save all the information of the form in multiple tables.
As of now i a m able to have a simple form and a process that save 1 question per request.
How do i achieve this. Please assist.

Do that using collections like in this example:
http://apex.oracle.com/pls/otn/f?p=31517:176
Once you are done, you may decide either to save that or to clean it up.

Editable ALV- Disable Add, delete row buttons

Hi,
I have an editable ALV using OO Grid. Some columns are editable and some are not using field catalog. I want to disable the 'add new row' and 'delete row' buttons. How to go about it ?
Regards,
Vin

You can simply add them to the "Exclude" table and pass them to the SET_TABLE_FOR_FIRST_DISPLAY method.
   data: iexclude type ui_functions,
   data: xexclude type ui_func.
    define macro_exclude.
     xexclude = &1.
      append xexclude to iexclude.
    end-of-definition.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_copy_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_delete_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_append_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_insert_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_move_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_copy.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_cut.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_paste.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_paste_new_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_undo.
    call method alv_grid->set_table_for_first_display(
        exporting
             it_toolbar_excluding = iexclude     "<--- Right HEre
             is_layout             = xlayout
        changing
             it_outtab       = izcmptrans[]

BPM Object Presentation - array items - (add / delete rows dynamically)

Hi,
We have a BPM Object presentation which uses a 'group' inner object to display ROWS of data. The presentation has an 'array0' created by default to handle the 'group' of rows. It also has the '+' and '-' buttons by default.
There is a field at the upper level which shows the 'sum' of values in individual rows. It needs to 'REFRESH' when an add (+) or deletetion (-) or rows happen.
But we see that all the controls (text boxes etc which are wired to the 'inner' bpm object of the group and the +/- buttons are one unit 'array0'. And the only method if at all, is an 'Event Listner' which is not showing any methods related to BPM Object.
Can anyone help us with a clue as to how to handle the '+' and '-' events or wire the 'array/group' events to code - any clue with 'events'?
This is a little urgent as it is an issue and we need to fix the same. Appreciate any quick responses/clues.
Thanks in advance,
-user8702013.

The SUM field needs refresh() method to be called to reflect the new value whenever we are adding/deleting rows.
To call this method for to show the reflection we have to declare a method on BPM object level which receives a argument of type ‘Fuego.Util.GroupEvent’, then in this method you can have your logic(here refresh() method is required to show new value on deletion/addition, hence this method is being called). This method can then be wired (it shows up) to the 'Event Listener' of the group/array.
The newly created method will be called whenever a new row is added/deleted (Event will be fired hence method call).

Add/Delete rows from ALV-grid

Hi to all,
i have 2 questions concerning alv-grids:
i have an alvgrid displaying a table and what i need is some functionality to add or delete rows from the alvgrid - how can i do that ?
within one row i have one field containing the status and i want to be able to select the status from a combo/dropdown-field and set it for this particular row.
thanks in advance!

Hi,
Report BCALV_EDIT_04 shows how to append and delete rows.
Report BCALV_EDIT_06 shows drop down list for cells in a column.
These report should be available in any R/3 system including all ABAP Preview versions.
Hope this can help.

Add/Delete row

Hello,
How can add a new row directly after the current row not at the end of the form?
For example: User fills the question/answer form and they want to add new row(s) to ones that already added. Suppose that they are at question 1, 2, 3 but realize that they want to add a new row between row#1 & 2 or row# 2 & 3 which can re-number to reflect the new row to the right number instead of at the end after row#3.
Can any one please advise.
Thanks,
Han

Hi Han,
Check out this example: http://assure.ly/gk8Q7a.
In particular Tables 5 (uses Tables) and 6 (uses Subforms). Basically I have set up the index cell as a button. When clicked it will "add" a new row directly underneath the row clicked.
The script is in fact doing two things, one directly after the other.
It adds a new row at the end of the table, and
Then it moves that new row based on the index of that new instance.
Does that make sense?
Niall

Add more rows problem

I have an advanced table that displays a single row. Users can use Add more rows if they require more.
I have 2 small isses.
Firstly, there are 2 fields. Cost Centre and description. Cost centre has an LOV and description is mapped and populated from the LOV as well.
When I click on add more rows, the description column of the first record is cleared.....I obviously want this to remain.
Second issue. When I choose the value from the LOV on rows 2 and above i want to ensure this has not been chosen before in a previous record - any quick way to do this>?
Robert

Regarding 2: You can write your Lov VO query with NOT IN :1. Use the CO in your LOV and try to get the value entered by user in above row(s) and bind it in LOV VO query using your Lov CO. Please note that LOV CO might get called before coming to page CO processFormRequest. So try to keep a stringBuffer value in OADBTransaction, which shall concat the values selected in all above rows. Use this value in LOV CO each time.
Hope it helps.

Add/Delete rows in TableView

hi all,
i wanna add rows in the tableView and also wanna delete the selected rows from the tableView.
how to do it?
regards,
purushothaman.

Hi,
As Harish said, use addElement to add elements to the Vector (using which you have created the DefaultTableViewModel and assigned it to your tableview).
Capture the index of the rows to be deleted and use
<Vector>.removeElementAt(index) to remove the specific rows.

Table layout w.r.t other tables and text while inserting/deleting rows.

I have 3 tables in a single page. One is left aligned and other two are right aligned. Then there is some text below the tables.
Now when I delete some rows from Table-1 the left aligned one, the Table 2 and text shift up filling the space below Table1.
Now I don't want the text/table to shift up/down when I add/delete rows from Table1 i.e Table1 should expand/contract in the empty space below it.
Now If I do the same thing for Table3 (Right aligned one) i.e add/delete rows there is no effect on text as shown :
All 3 tables are same and have exact positioning and other properties.
Please suggest any solution as I would be populating the table through word automation service (interop).

Another approach would be to use nested tables, with your 'outer' table having two columns and the inner tables going into different columns. You can hide the outer table's cell borders so its presence is less apparent. If the Outer table has auto row
height, it will adjust to accommodate whatever row addition/deletion you do to the inner tables. The only proviso is that the inner tables shouldn't have 'around' text wrapping. The two rhs tables can go into the same cell - all they need is a separating paragraph.
With this layout, the text will always remain below the outer table.

Adding/Deleting rows in a Table

I am trying to get a couple of buttons to work in a table to add/delete rows. I have followed the directions in the LiveCycle designer help and it isn't working.
In a test setup the only difference I can see from the help file is my Table is called Table1 and the subform containing the 2 buttons is called Subform1
I have therefore amended the script for the click event for the AddRow to
"Table1.Row1.instanceManager.addInstance(1);"
Any ideas where I am going wrong?
TIA

Hi,
My usecase is that user enters a url with parameters for example in the text box--> http://host:port/employee/all?department=abc&location=india. Now i want to parse this url , get the parameters out and put it in the table so that it is convenient for users to modify these parameters. User has a option to add and delete the parameter in the table. So once all this is done and user clicks on say save i don't need to send this table to server. i just have to make sure that the values added/deleted from the table are in sync with the url. So in the server i get all the parameters from the url and continue.
Since this is only needed on the client side i wanted to know if we can create a table with no values and then say on tabbing out of the url text box call a javascript that takes value from it and adds new rows to the table.
I am using JDEVADF_MAIN_GENERIC_140109.0434.S

Problem with creating and deleting row in table

Hi
I'm using JDev11.1.1.2.0. I have a table "A" with primary key X -> CHAR(1). I have created Entity and ViewObject (with the primary key X).
I created an editable Table with CreateInsert and Delete actions.
When I click Insert, a new record is added and I enter some data. Then I move selection to some other row, and return back to the new row. When I press Delete, It does not delete the new row, but the previous one selected.
In the console, when I navigate back two the new added record: <FacesCtrlHierBinding$FacesModel><makeCurrent> ADFv: No row found for rowKey: [oracle.jbo.Key[null ]].
I tried the same scenario with a different table, that has RowID as a primary key and it works correctly.
Any Idea why this is happening ? I suppose it's connected somehow with the primary key.
Thanks
agruev
Edited by: a.gruev on Nov 26, 2009 9:47 AM

I changed my entity: unchecked the X column to be primary key added RowID as a primary key. Now it works.
What's wrong with my CHAR(1) as a primary key ?
I also tried to add a Refresh button:
<af:commandButton text="Refresh" id="cb3"/>and in the table add a partialTarget to the button. Now when I add new row and press the Refresh button - then it works.
So it seems that the problem is when I add new row and enter data, the table is not refreshed and the row is missing it's primary key.
Any solutions?

Facing problem While deleting rows and adding rows

Hi,
In my form i have pass values to table rows by selecting values from Dropdown list.
i have taken 3 hidden obj and passing the dropdown values to hidden objects and then from hidden objects to table rows.
h1,h2,h2 are hidden obj
EMPNO,EMPNAME, DESIGNATION are drop downlist
i have add button with the following code
if(form1.P1.ItemSet.EMPNO.rawValue != null){
form1.P1.ItemSet.instanceManager.addInstance();
form1.P1.execInitialize();
var dynamicArray = form1.P1.resolveNode("ItemSet[" + arrayIncri + "]");
dynamicArray .EMPNO.rawValue = form1.P1.hidden.h1.rawValue;
dynamicArray .EMPNAME.rawValue = form1.P1.hidden.h2.rawValue;
dynamicArray .DESIGNATION.rawValue = form1.P1.hidden.h3.rawValue;
arrayIncri++;
form1.P1.SF1.EmpID.rawValue = null;
form1.P1.SF1.EmpName.rawValue = null;
form1.P1.SF1.Designation.rawValue = null;
My delete button code is
_ItemSet.removeInstance(this.parent.index);
form1.P1.execInitialize();
My problem is adding is happening while click and deleting is happening to the perticular row but once i delete paricular row then again if i want to add new row then it is taking null values . and agian if i click add then the values are passing to the next row

What i did was, i run the reports /VIRSA/ZCC_DOWNLOAD_DESC & /VIRSA/ZCC_DOWNLOAD_SAPOBJ and uploaded them as below in GRC.
Text Objects - /VIRSA/ZCC_DOWNLOAD_DESC
