Add the line in the table of the ADF
I am trying to add a new line to the table of the ADF. Here are my steps:1 create new entities to tables (new-> EJB-> entities from Tables)
2. create the Session Bean (new->-> Session Bean EJB) with all required methods for earlier of the entity created
3 create the control of data off of it (right click-> session bean create a Data control)-, it creates 'testFindAll '.
4. After these steps, I drag / drop my "testFindAll" of data controls to form and create the table
5. now I do drag & drop operation Create since my 'testFindAll-> operations", create a button and move the action to create CreateInsert
And now, eating disorders: ((...)) When I click on the button to add the new line I get null pointer exception. Here is the part of the trace:
java.lang.NullPointerException

I know I can do it if you create ViewObject rather than Tables and SessionBean entities. But I need this approach.
Thank you very much!
Hi Goran,
What is your version of JDev? You try with EJB 3.0 or 2.1? I just tried (with 3.0) and it works fine (tested in JDev 11.1.1.2.0).
Here's my pagedef
Infact, I don't have to change the action of creation at CreateInsert. By default, it is CreateInsert only.

Add a line in a table with a button
Good day to all;
I think I have now lost...; >)
Life cycle of Designer 8.05
In any case, if the user of the form requires additional lines to enter the infoamtion, I want them to be able to add a line using a button. I tried to use the following

I use Apex 4.0 and I'm trying to view multiple empty lines in tabular form, when a page loads.

Examples or ideas on how to do that?

Add sequence to add a line in a table?
Version: 4.1.1
Hello
I have a tabular form on a table that has a serial number filed as primary key. This isn't a sequence as such, but I'm just a series max + 1 to get the next value. Forms, I had a trigger when a new record is added so that the next serial number is automatically filled when we hit add new record.
In the Apex, is this possible when we hit the button Add row in a tabular presentation, we can get the series maximum + 1 and automatically populate this field?
Any suggestions please?
Thank you
RyanThere are a lot of options, you can create a hiden form item and set the value to them (so you must change the default type for the value of the element) or function in DB.

How to get rownum of the last line in a table?
Hello
I need to add a line slot-shaped table with the dynamic value.
I add a line slot-shaped table with existing lines so I need to get a rownum of the last row of tabular presentation.
I'm using a process like this:
Declare
l_value varchar2 (200);
number of rownum_value;
Begin
l_value: = wwv_flow.g_x01;
rownum_value : = wwv_flow.g_x02;
HTP.p ("< class td =" child"> ');
HTP.p (APEX_ITEM. DISPLAY_AND_SAVE (p_idx = > 3,
p_value = > l_value,
p_item_id = > 'f03_000 ' | ROWNUM_VALUE - here is Rownum value
));
HTP.p ("< table > '");
HTP.p ("< class td =" child"> ');
HTP.p (to_date (sysdate));
HTP.p ("< table > '");
HTP.p ("< class td =" child"> ');
HTP.p (APEX_ITEM. CHECKBOX2 (p_idx = > 5, p_value = > 'Y', p_item_id = > 'f05_000' |) ROWNUM_VALUE -here is Rownum value
));
HTP.p ("< table > '");
And I use the dynamic action with Ajax to pass values to the process:
(function () {}
get var = new htmldb_Get (null, $v ('pFlowId'), 'APPLICATION_PROCESS is ADD_VALUE', $v ('pFlowStepId'));
get.addParam ('x 01', $v ('P2_VALUE'));
get.addParam ('x 02',SOME_ROWNUM_VALUE); Here, I need to get the value of Rownum
gReturn = get.get ();
get = null;
gReturn = (! gReturn)? ' null': gReturn;
var table1 = document.getElementById ('tabform_TABLE');
Table2 = table1.getElementsByClassName ("uReport") var [0];
TBODY var = table2.tBodies [0];
var row = document.createElement ("TR");
row.innerHTML = gReturn;
tbody.appendChild (row);
})();
How can I get a value of rownum in the last row of my tabular form?
I prefer to use JavaScript, but any other solution would be much appreciated.
I'm on Apex 4.2
Thanks to you all.

always fill the last line of a table (which may expand)
Hi, I have problems with a button in the table A that adds a line to another table (table B) and then fills automatically some row of the table (table A) data in the newly created line in the other table (table B)
Here is my code (then) - I should also mention that table A has a button to add several lines to itself:
It works almost - however, it does that if the amount of lines in every game table - which they are not necessarily that the user may or may not opt to add the row of the table has to table B. eg. A table might be deep 4 rows, but the table B can have only 2 rows.
tableB.row.addInstance (0);
vCol1 var = this.resolveNodes ("tableA.row.cellA");
vCol2 var = this.resolveNodes ("tableB.row.cellA");
vCol3 var = this.resolveNodes ("tableA.row.cellB");
vCol4 var = this.resolveNodes ("tableB.row.cellB");
for (var I = 0; vCol1.length i < ; I ++) {
vCol2.item (i) .rawValue = vCol1.item (i) .rawValue;
vCol4.item (i) .rawValue = vCol3.item (i) .rawValue;
}
I'm new to scripting (learning on the fly), so my question is, given that the first command is to add a new row to table B, can I change the code so that vCol4 and vCol2 var are always the very last line created? In this way, all the previous lines that have been added will be shunt down in the list and will not be affected, but click on the new button? Or is there a better way to do this.
Hello
I think the key here is that the addInstance method returns the line he simply added. If your add-in can be something like;
var button = xfa.host.messageBox ("' you are about to ADD this entry in the Table B. would you continue?", "add to table B Section"1, 2 "");
If (button is 4)
{
newRow = tableB._tableBrow.addInstance var (0);
newRow.cellA.rawValue = cellA.rawValue;
newRow.cellB.rawValue = cellB.rawValue;
}
I don't know how you want that table a delete button to work? Should you remove the first row B of the table with a cellA and corresponding cellB?

I added a button to a form to add a line in a table. He was working. I passd of the subforms to the top and now the button does not work.
Can someone take a look and help me understand what I am doing wrong?
In addition, I can't understand today why I can't insert a copy of the form! Any clues?
Thank you
MDawn
There's something wrong with the code that you used to create an instance. You're missing instanceManager in your script. Same is the case with the button Delete.
Header.detailHeader. instanceManager.addInstance (1);
I have sent the form fixed in a separate email. I hope this helps.

Add a line to the table programmatically
Hello
How do I add lines to the af: table of the java class? for that to editable object view exist on the JSPX page
Thank you
Chaya
You can see the following code to add a line at the end of the table programmatically:
public String cb1_action() {}
Add the code in the event here...
BindingContainer bc is BindingContext.getCurrent () .getCurrentBindingsEntry ();.
JUCtrlHierBinding hierBinding = (JUCtrlHierBinding) bc.get ("EmployeesView3");
DCIteratorBinding dciter = hierBinding.getDCIteratorBinding ();
NavigatableRowIterator nav = dciter.getNavigatableRowIterator ();
NewRow row = nav.createRow ();
newRow.setNewRowState (Row.STATUS_INITIALIZED);
Line lastRow = nav.last ();
int lastRowIndex = nav.getRangeIndexOf (lastRow);
nav.insertRowAtRangeIndex (lastRowIndex + 1, newRow);
dciter.setCurrentRowWithKey (newRow.getKey () .toStringFormat (true));
Returns a null value.
}
For the case where you must add a line in different places of the table, see the link below:

Hello
If you work with the advance table so you have a default option to create a blank line, please through the topic "add another line."
Jdev Guide.
If you work the ordinary table area, then you can follow the below proposed code.
Create a new item of type button (no submit button) and handle the event in your controller class PFR
String addRow = pageContext.getParameter (EVENT_PARAM); "addRow" is an event attached to table
If ("addAnotherRow". Equals (AddRow))
{
am.invokeMethod ("AddRow");
}
In the AMimplementation class:
Public Sub::AddRow()
{
OAViewObject headerVO = (OAViewObject) getsdaPacelineWorkupHeaderUpdateVO1 ();
rowh = (sdaPacelineWorkupHeaderUpdateVORowImpl) headerVO.getCurrentRow () sdaPacelineWorkupHeaderUpdateVORowImpl;
rowh.getPacelineHeaderId ();

Click the "add another line" adv table must fill in the data in tbl.
Hi all
I have a requirement of value of column in table adavance automatically filling in read-only mode when the user clicks on the add another button in the row.
Initially when the page loads there is no data and therefore no line in the table in advance. And advanced table will have the "add another line." When the user clicks this button, the first column of the table advance must complete with so-called values a contant '1'.
Can someone please provide a code example in how to achieve this?
Thank you
SunnyHi Sunny,
Please use the controls below before creating and inserting the line so this new line will be created at the end.

Hi writers,
I created and filled a complex picture, but I would like to add three lines of header. When creating (table > insert table) I was clear no header row. I used extensively to merge cells and custom power (it's actually a menu tree).
I can insert rows at the top, but they are stored in body; I need three rows to repeat at the top of each page.
Can I insert lines of position, or convert lines of body positions?
I use 7.1p116 to Frame.
-Derek
Hi Derek,.
You can not convert existing body lines to the header lines.
However, you can add header lines. In the menu, click table
'Add some rows or columns. In the dialogue box, select 'Add 3 Row (s) under the heading'.
Then copy your content in these lines.
If you do something like that more often, you could buy

Apex 4.2: The button "Add a line" does not not in table form
Hello
We have an application migrated from 3.2 to 4.2 Apex
Afterwards, the 'Add Row' button does not work. When I try to click that, new line is not get added.
I even tried to delete the tabular form and creates a new array of 4.2 Apex environment itself, but of no use, new line is not get added.
"Also, is to launch a page fault"Message: 'length' is null or not an object"
Browsed little of the previous announcement in OTN for this problem and found that by changing the theme, this problem can be solved.
'Length' is null or not an object for tabular forms V4 error
Apex 4: the 'Add Row' button doesn't work is not in tabular form
The user is comfortable with the current theme and does not change the theme.
Current theme used is "blue-gray - 13.
Is it by a patch or workaround, we will be able to do the work of button "Add a line" normal.
Kindly guide me in this issue. Thanks in advance.
