Getting the value of a check box - annoying error

Hi guys,
Ive got a web page with sets of hidden variables and check boxes which relate to different courses, but when I try and itterate through the value of the check box to see if it is checked or not im getting an outofIndexArray error because im using
for(int i=0; i<paramValues.length;i++)
{ which relates to the number of courses which does agree with the number of check boxes, but not when they are unchecked.
i.e. when some of the boxes are not checked then it gives this error, however when all are checked it is fine.
How do I get it to not give this error, i.e. how do I set the value of a check box when it is not checked as on several web pages it shows how to set the value when they are checked.
thanks
tzaf

i don't see the error, can you post some more code?
what is paramValues?
you iterate over the number of checkboxes?
every checkbox can be selected or deselected (boolean isSelected())
how can there are an exception?
what is the array where the exception occur

Get the value of output text box in javascript

Hi all,
I am trying to retreving the value of output text box using getElementById('form1:outputText3') but was not able to get it.
Googled it but didnt find any way to get it on the page itself without going to backing bean
jdeveloper version 10g
Thanks in advance

Hi,
I think this is because out put text is not a component but text written to the page. So I thin you would have to parse the generated HTML for it or use a inputText field and set it to read only

Getting the value of a combo box from a button

Hi everyone, i wondered if anyone knew how to get a system combobox value from the item pressed event of a button. The code below only gets the last value rather than the one currently selected.
Case SAPbouiCOM.BoEventTypes.et_COMBO_SELECT
                    If pVal.ItemUID = "3" And SAPbouiCOM.BoEventTypes.et_COMBO_SELECT Then
                        oCombo = oForm.Items.Item("3").Specific
                        ComboBoxValue = oCombo.Selected.Value
                    End If
If pVal.ItemUID = "ViewDocBtn" And SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED Then
                        SBO_Application.MessageBox("ComboBox:" & ComboBoxValue
                    End If
Has anyone got any idea why it is pulling out the last selected combobox value rather than the current one?

How do I get the value of a comboBox item that is in a grid?

Hi all,
I have a data grid that has comboBoxes in two of its columns.
What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.
I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done. Any help greatly appreciated.

This code shows how you can do it if you know the dataProvider fields for the ComboBox data.

Getting the value from a Drop Down Box

I'm working on a database project to keep track of our Blackberrys. The problem I'm having is entering the values for two drop down boxes. The page I'm working on enters the FirstName, LastName, Department, and Location. Department and Location have thier own Primary Keys and are foreign keys in the Person table. Departments and Locations are aligned by numbers like 1 = Ohio, 2 = Chicago. They
don't automatically increase. The problem I'm having is entering them as a foreign key in the Person Table. I'm not sure if I use a getValue or getSelected or some other code to get the values to populate in the Person Table. I just keep getting a can't add department or location to table.
public String newUser_action() {
// TODO: Process the button click action. Return value is a navigation
// case name where null will return to the same page.
if (personDataProvider.canAppendRow()) {
try {
RowKey rowKey =
personDataProvider.appendRow();
personDataProvider.setValue(
"DBO.PERSON.FIRSTNAME", rowKey,
firstName.getText());
personDataProvider.setValue(
"DBO.PERSON.LASTNAME", rowKey,
lastName.getText());
personDataProvider.setValue(
"DBO.PERSON.DEPTID", rowKey,
department.getSelected());
personDataProvider.setValue(
"DBO.PERSON.LOCATIONID", rowKey,
location.getSelected());
personDataProvider.setValue(
"DBO.PERSON.BEGINDATE", rowKey,
newDate.getText());
//personDataProvider.setValue(
"DBO.PERSONDEVICE.AQUIREDATE", rowKey,
newDate.getText());
personDataProvider.commitChanges();
info("New User " + newUser.getText() +
" added to USER table");
newUser.setText(null);
} catch (Exception e) {
log("Cannot add new User ", e);
error("Cannot add new User: " +
e.getMessage());
} else {
log("Cannot append new User");
error("Cannot append new User");
return null;

Getting the Values from a Tiled View

Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
Namburi

Namburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))

How to get the value from the checkbox

Hi All,
Good Evening,
i want to get the value from the check box.
for this i wrote like this
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String val=cbb.getvalue(pageContext).toString();
val getting the value only when checkbox is checked.
suppose check box is not checked that time i got NULL POINTER exceptionn.
so
i tried the following way alsoo
string val=pageContext.getParameter("item240");
here val return 'on' only when checkbox is checked.
otherwise NULL value returnss.
but i want to get the value is 'Y' when i am checked the checkbox
otherwise returns NULL valuee.
already i set the checkbox properties alsoo
Checked :Y
unchecked:N
pls tell me

Hi,
use
try
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String test = cbb.getvalue(pageContext).toString();
catch(Exception e)
String test = "";
this way you can handle null pointer exception.

BDC-How to get the value of the screen field

Hi All,
I am facing a problem while writing the BDC code for the XK02 transaction.
Recording:
We have recorded like this :after giving the values in the initial screen(vendor no and purchase group and selecting the purchasing data check box) and enter into the second screen and then click on alternative data icon.There we ll have set of plants we have to check auto ordering (by selecting the plant and click purchasing icon)for the plants which are in the given file.
Problem:
Suppose there are five plants(like 1,2,3,4,5) for a particular vendor but we are having only three plants in the file for which auto ordering check has to be done.The problem is that its doing auto ordering check for the first three plants(1,2,3) in the transaction.But in the file we are having Plants like (1,3,5).How to get the screen field value directly or is there any other way to resolve the problem?

Dear Raja,
You cannot get hold of screen values while running through the BDC Operation.
Only way you can get the value --> populating an Internal Table from the Database Table.

Abir

NullPointerException - Cannot get the value from variable f_cashGiven

In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!

If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.

All I want to do is get the value associated..

All I want to do is get the value associated with a dropdown item...
1. I have a combo box
2. It has text values that you can click
3. The text values have export values associated with it
4. When I click a text value from the list, I want to get the numeric value associated with it
Example combo box:
"Orange" has the export value of "1234"
When I click "orange" I want to get the export value "1234" and alert it to the screen
I'm using javascript, here's what I have so far:
In the combo box properties I have the following validation script:
theFruitClicked();
I have a function in the document javascript:
function theFruitClicked()
app.alert(event.value);
This is alerting the text value not the export value.
What else should I do to get the export value?
Thank You.

How to get the value from a JavaScript and send the same to Java file?

Hi.
How to get the value from a JavaScript (this JS is called when an action invoked) and send the value from the JS to a Java file?
Thanks and regards,

Yes, I am trying with web application.
In the below code, a variable 'message' carries the needed info. I would like to send this 'message' variable with the 'request'.
How to send this 'message' with and to the 'request'?
Thanks for the help :-)
The actual JS code is:
function productdeselection()
var i=0;
var j=0;
var deselectedproduct = new Array(5);
var message = "Are you sure to delete Product ";
mvi=document.forms[0].MVI;
mei=document.forms[0].MEI;
lpi=document.forms[0].LPI;
if(null != mvi)
++i;
if(null != mei )
++i;
if(null != lpi)
++i;
if(null != mvi && mvi.checked)
deselectedproduct[++j]="MVI?";
if(null != mei && mei.checked)
deselectedproduct[++j]="GAP?";
if(null != lpi && lpi.checked)
deselectedproduct[++j]="LPI?";
if( 0!=j)
if(i!=j)
for (x=0; x<deselectedproduct.length; x++)
if(null != deselectedproduct[x])
message =message+ "-" +deselectedproduct[x];
alert(message);
else
//alert(" You cannot remove all products!");
return false;
return true;
}

Hello ,
          Check this code,
DATA: test_datum1      LIKE sy-datum,
           test_datum2      LIKE sy-datum.
WHEN 'TEST1'.
          IF i_step = 2.
      LOOP AT i_t_var_range INTO loc_var_range
        WHERE vnam = 'TEST2'.
        test_datum1      = loc_var_range-low.
    CONCATENATE test_datum1(6) '01' INTO test_datum2.
    CLEAR l_s_range.
    l_s_range-low   = test_datum2.
    l_s_range-high = test_datum1.
    l_s_range-sign = 'I'.
    l_s_range-opt = 'BT'.
    APPEND l_s_range TO e_t_range.
hope it helps,
