Hi,
Please go through the tutorial "Understanding scope and managed beans". This is available at:

Problem with CheckBox as table cell renderer

i m making a JTable having three columns.
i m also making a cellRenderer of my own MyRenderer
extending Jcheckbox and implementing TableCellRenderer
now i m setting MyRenderer as renderer for third column in my table and
DefaultCellEditor with jcheckbox as parameter as cell editor for this column
the code is like this--------------------
****making of JTable****
table= new JTable(3,3);
JScrollPane scrollPane = new JScrollPane(table);
TableColumn tableColumn = table.getColumn("Male"); // let us suppose that this gives third column
tableColumn.setCellRenderer(new MyRenderer ());
tableColumn.setCellEditor(new DefaultCellEditor(new JCheckBox()));
*****The classs implementing TableCellRenderer is given below******
class MyRenderer extends JCheckBox implements TableCellRenderer{
public MyRenderer(){
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int column){
if(value != null){
Boolean booleanValue = (Boolean)value;
setSelected(booleanValue.booleanValue());
return this;
***********************************Problem****************************
The problem is that when we click on the cell of that column first time,
all the cells are selected.
I don't want to use getColumnClass() method for this problem .
If possible , please give some other solution.
what is the problem behind this,If anybody can help us.
Thanks in advance.

I think the problem is, when the value is null the checkbox return with the selected state, b'coz u r
returning the checkbox (as it is). so pl'z try with below code (ADDED).
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int column){
if(value != null){
Boolean booleanValue = (Boolean)value;
setSelected(booleanValue.booleanValue());
else /// ADDED

Problem with checkbox group in row popin of table.

In table row popin I have kept Check Box Group.I have mapped the texts property of checkbox group to the attribute which is under the subnode of the table.the subnode properties singleton=false,selectioncardinality=0-n,and cardinality=0-n.
if there are 'n' number of records in the table.each record will have its own row popin and in the row popin there is check box group.
the check box group in the row popin belongs to that perticular row.
but the checkboxegroup values in row popins of all the rows are getting changed to the row which is lead selected.
The same scenario (table in the row popin is showing the values corresponding to its perticular row and all the table values in popin are not getting changed to the one lead selected in the main table)is working fine with the table in place of checkbox group in row popin with datasource property of table binded to the subnode
I cant trace out the problem with checkbox group in place of table.
Please help me in this regard.I have to place check box group in place of table in row popin.
Thanks and Regards

I have done the same thing successfully with normal check box ui element. Try using check box in your tabel cell editor instead of check box group.

Problem with checkbox column in matrix

Hello.
I have a little problem with checkbox column in matrix.
Column is binded to the UserData.
It has ValOn="Y", ValOff="N".
I use C++. It is wird problem. In matrix I have 10 columns - scrollbar role and if You want see checkbox column, You must role to the right. If this column is on the screen, and I use:
checkcell->PutChecked(VARIANT_TRUE);
then the checkbox is cheched, and if the checkbox isn`t on the screen and I use this comment - it nothing happening.
I tried to use ValOn="Y", PutChecked...
The problem i solved if the column is on the screen - if the column is first in matrix or second, but if it`s last I have a big problem.
My column with checkbox is not editable, but I tried to make it editable, check it, and then make it uneditable - the same efect.
How can I solve it ?
Sorry for my english.
Kamil Wydra

Hello Kamil,
I am not sure about your problem, but here is an example of how to use checkbox in UI API.
First, create the matrix with checkbox column in Screen painter, and the output is an xml file, like this. Type as 121 indicates that it is a check box.
- <column AffectsFormMode="0" backcolor="-1" description="" disp_desc="0" editable="0" right_just="0" title="Rented" type="121" uid="Rented" val_off="N" val_on="Y" visible="1" width="41">
<databind alias="U_RENTED" databound="1" table="@VIDS" />
<ExtendedObject />
Second, bind the column to table from DB. This is a bug of 2004 Screen Painter, so if you are using 2005 Screen Painter, there is no problem.
Third, when you open the form, you can check and uncheck the cell.
BTW, please set the editable of the column to true.
Hope this helps,
Nick

I had the same problem. I read you post and was so disappointed that no one had answered you. But I have a good news for you :) My team leader managed to solve this awkward problem.Add to h:selectBooleanCheckbox style="z-index: 20;" so that it is "above" the table row that fires its own onclick event.

Problem with Checkbox that disables/enables other components.

Hi
As I show in the title, I have problems with a checkbox that enables/disables another components (three exactly).
I have done the follow:
1.- Set property "AutoSubmit" true in the SelectOneChoice
2.- Set "Disabled" property true or false depending if the SelectOneChoice is selected or not
(#...selectBooleanCheckbox.value?false:true})
3.- Set the Partial triggers to the SelectOneChoice in the three components.
CASE 1: The SelectOneChoice is unmarked. The three components appears disabled and when I mark the SelectOneChoice, this components appears enabled. The thing works ;)
CASE 2: The SelectOneChoice is marked. The three components appears enabled and when I unmark the SelectOneChoice, the components continue enabled. They don't disable until I press the submit button.
how can i make that the components appears disabled when i unmark the checkbox?
i try with de ChangeValueListener, but it only works where the SelectOneChoice changes from unmarked to marked.
thanks!

I think the problem is, when the value is null the checkbox return with the selected state, b'coz u r
returning the checkbox (as it is). so pl'z try with below code (ADDED).

Problem with checkbox column in ALV popup (ABAP)

Hi, the problem is: I've created the code below for maintaining a popup with an ALV table inside. One of the column is a checkbox field. When I run first time the popup, it run well, when I clode the popup window and then I run for second time the popup, i see all the columns except those with the checkbox. Someone else have encountered the same proble, if yes someone could me explain that? Here's the code:

endmethod.
Thanks for answers.

This is just some guessing - but try and set a breakpoint in the wddoinit of your popup. I'm betting that it isn't being executed on the second call because the original instance is reused.
Take a look at the properties on the view for the popup. You might try changing the lifetime of the view from "framework controlled" to "when visible".

Problem with checkbox selection in Tableview

Hi All
I am using table view with 8 columns - in the last 4 columns i have checkboxes for user input - i have a strange problem - when the table has multiple entries - for the last column i can only select the checkbox on line 1 - and i cannot select the checkbox on the remaining entries below - but for the other colums with checkboxes this is not the case
The selection mode for the table is no line selection - since the table is already displayed with input enabled fields - this is to reduce the no of clicks for user
Can anyone point out what is going wrong - how can i fix this - what i am doing wrong ?
Thanks
Sen

Hi
When i click on the checkbox for the 2nd or 3rd rows of the last column - nothing happens - the checkox is still active but nothing happens -
this is the tableview code
<htmlb:tableView id              = "Detail"
                 design          = "ALTERNATING"
                 headerText      = "Header Text"
                 onNavigate      = "onMyNavigate"
                 emptyTableText = "test"
                 onRowSelection = "onMyRowSelection"
                 fillUpEmptyRows = "false"
                 footerVisible   = "true"
                 visibleRowCount = "5"
                 table           = "<%= DETAILTAB %>"
                 iterator        = "<%= iterator %>" >
and this is the code for the last column
<htmlb:tableViewColumn columnName         = "OBSOFLGICON"
                           width               = "3"
                           type                = "user"
                           horizontalAlignment = "CENTER"
                           title               = "Obs" >

Interactive form: problem with ValueHelp in table

I have InteractiveForm element in my WDA.
The form has Table. One of the columns of the table is ValueHelp button from WebdynproNative library.
The form executes ContainerFoundation_JS code on the ValueHelp click event just fine.
The Search help gets called just fine.
My problem is that the Table cell on the form doesn't get populated with the value selected on the search help.
The Table is bound ro WDA context.
I am afraid that Adobe gets confused with the row number to return the Help value.
I have no problem with ValueHelp button on a single TextField (not in a table).
But within the Table....
Is ValueHelp working in a Table?
Any help is greatly appreciated,
Tatyana.

Ralph,
I followed you advice and created identical WDA's and forms in "ECC box" and "RPM box".
To clarify, "ECC box" is:
- component version = SAP ECC 6.0
- SAP_BASIS package level 20
"RPM box" is:
- component version = SAP Netweaver 2004's
- SAP_BASIS package level 17
I didn't have problems in "ECC box".. Value help in table was working.
There was some disconnection between WDA table and PDF table in "RPM box".
I noticed differences in schemas generated from WDA: "RPM box" schema was not same as "ECC box" schema.
I believe that it is WDA issue giving me a problem, since I generated XML schemas using right click on IneratctiveForm object in WDA.
We defenetly need to update RPM system to a nigher package or try to find OSS note to fix the issue.
Points are awarded.
Ralph, thank you very much for helping me to identify the problem!
Tatyana.
Otto,
I thought you are SAP mentor...

Problem with checkbox value and app.settings.getSetting()

Hello everyone.
I`ve got a problem with getting saved settings for checkbox.
Saved settings doesn`t apply on checkbox value.
It`s strange, but it always "true".
So here piece of code:
checkMe = 11;    //any value for the first time running
if (app.settings.haveSetting("savea", "chck")) {
                      checkMe = app.settings.getSetting("savea", "chck"); // get saved value, else 11
                      alert("checkMe = "+checkMe)
                    if(checkMe == 11){
                        checkMe= false;   //if there is no saved settings, checkbox value will be false/ unchecked
                        alert("You run this script first time, so manual value will be 'false'")
                        }else{
                            checkMe = app.settings.getSetting("savea", "chck");     // if saved settings exist, get true or false
     alert("Yes, checkMe will = "+checkMe)
win.checkPanel.chkOne.value = checkMe; /// checkbox value will equal saved checkMe
var fff = win.checkPanel.chkOne.value; // string for alert
alert("aha! but checkbox value is = " +fff+ "\n Why so?")     // here we`ve got always "true"
win.checkPanel.chkOne.onClick = function () {
    var path11 = win.checkPanel.chkOne.value; // checkbox value to variable
    app.settings.saveSetting("savea", "chck", path11); //saving checkbox value
    alert("Saved this value - " + app.settings.getSetting("savea", "chck"))
win.checkPanel.chkOne.value is always true.
Can someone exmplain why and how to get rid of this static value?
P.S. just in case, here is full code:
function mainFun()
    this.windowRef = null;
mainFun.prototype.run = function()
    /*----- UI -----*/
          var retval = true;
          var win = new Window("palette", "Check option", [150, 150, 460, 455]);
          this.windowRef = win;
          win.checkPanel = win.add("panel", [25, 150, 285, 265], "Checkbox");
          win.checkPanel.chkOne = win.checkPanel.add("checkbox", [10, 15, 125, 35], "Checkbox One");
          //win.checkPanel.chkTxtOne = win.checkPanel.add('edittext', [140, 15, 230, 35], '');
     win.quitBtn = win.add("button", [110,275,200,295], "Close");
checkMe = 11;    //any value for the first time running
if (app.settings.haveSetting("savea", "chck")) {
                      checkMe = app.settings.getSetting("savea", "chck"); // get saved value, else 11
                      alert("checkMe = "+checkMe)
                    if(checkMe == 11){
                        checkMe= false;   //if there is no saved settings, checkbox value will be false/ unchecked
                        alert("You run this script first time, so manual value will be 'false'")
                        }else{
                            checkMe = app.settings.getSetting("savea", "chck");     // if saved settings exist, get true or false
     alert("Yes, checkMe will = "+checkMe)
win.checkPanel.chkOne.value = checkMe; /// checkbox value will equal saved checkMe
var fff = win.checkPanel.chkOne.value; // string for alert
alert("aha! but checkbox value is = " +fff+ "\n Why so?")     // here we`ve got always "true"
win.checkPanel.chkOne.onClick = function () {
    var path11 = win.checkPanel.chkOne.value; // checkbox value to variable
    app.settings.saveSetting("savea", "chck", path11); //saving checkbox value
    alert("Saved this value - " + app.settings.getSetting("savea", "chck"))
          win.quitBtn.onClick = function() {
              win.close();
    win.center();
          win.show();
          return retval;
if(typeof(mainFun_unitTest) == "undefined") {
    new mainFun().run();

Played around with different values, combinations...
Doesn`t work too:
checkMe = 111;    //any value for the first time running
if (app.settings.haveSetting("333", "check")) {
                      checkMe = app.settings.getSetting("333", "check");
alert(checkMe);
                if(checkMe == 111){
                         win.checkPanel.chkOne.value= false;
                        }else{
                            if (checkMe != false){
                            win.checkPanel.chkOne.value= true;
                            }else{
                            win.checkPanel.chkOne.value= false;
win.checkPanel.chkOne.onClick = function () {
    var path11 = win.checkPanel.chkOne.value;
    var path12 = path11.toString();
    app.settings.saveSetting("333", "check", path12);
    alert("Saved value - " + app.settings.getSetting("333", "check"))

Problems with calculation in table footer

I’m working on a 'dynamic form’ with an expandable table (i.e. the user presses a button to add a new row), there are cells in each row for beginning month & ending month, plus an autocalc total field containing the formula: “ending – beginning +1” (which accurately calculates total months e.g. Jan-Dec = 12 months). There is also a ‘total months’ field in the footer which sums the row ‘total’ cells. The problem I have is that the user could add a blank row throwing off the total cell in the footer. Any suggestions to accomplish my goal of presenting accurate total in footer while ‘idiot proofing’ the form?

Problem with loading fact table in OWB3i

Hi,
I have a problem while trying to load a fact table using OWB 3i. Let me explain the situation :
I have 2 dimensions: Customer, Product say.
I have loaded the dimension tables separately, successfully using different mappings from source tables.
Now I want to load the fact table with the corresponding warehouse keys from these dimension tables through lookup transformation.
When I try to bring to lookup transformations for the 2 dim. tables, it gives an error--"Source and target are bound to different data providers". Using 1 dim table and 1 corresponding lookup transformation , the fact table is successfully loaded.
How to load a fact table when there are more than 1 dim. tables using lookup ?Is there any other way of solving the same problem?
Any suggestion will be highly appreciated.
regards
Dipanjan

Simply, try joining source tables with the join operator. In wich way you can create a single source object into the mapping suitable to be connected with yours fact tables.
Greetings

Problems with Java Dictionary Tables

Hi Experts,
I have some problems with the Java Dictionary tables that I have created for my
application. There are around 15 dictionary tables, each one of them having
several hundred records, added in due course.
As much as I understand these tables (created using the dictionary perspective)
are stored in the default schema of the J2EE engine where the dictionary project
is deployed and there is no direct way to insert records into these tables, we have
to separately write methods to insert, update and delete records.
I've already done this. Now the problem is that i have moved my project DC from
development to testing. Now here the tables are existing, but not the data that i
inserted during development.
NOW, the main question: IS THERE ANY WAY IN WHICH I CAN TRANSFER
THE CONTENTS OF THESE JAVA DICTIONARY TABLES??
I have tried solutions like creating a DBLINK between the databases, but it is
tedious, and unpredictable in behaviour. Also Please do not advise to first
download them to excel and then upload using jxlapi, etc.
Thanx in Advance.
Alka.

Hi Alka,
The dblink is a good solution, but just a bit slow. You can also use a SQL Loader, first export the data from the source table in a text file (i.e. using a tool like TOAD), then sql loader loads the data in the destination table. This is more fast.
Hope this help,
Vito
