Checkbox group

Hello,
I have three checkboxes in a row. I select them, click Layout, and the Group commnd is grayed out. What is the secret to group objects so that you can only check one checkbox? Right now in the form all three checkboxes can be filled in. I've read all the help directions and cannot figure it out.
Thank you

Well, you can do that by inserting a script, but radio buttons do that with no script involved. If you want to do it with checkboxes, here is the script (to be placed in the click event). You'd need to give the checkboxes unique names and you'd need a script for each of the other boxes. So for 3 boxes:
if (this.rawValue == 1) { //this stands for current checkbox
formName.subformName.CheckBoxName1.rawValue = 0 // clear checkbox
if (this.rawValue == 1) { //this stands for current checkbox
formName.subformName.CheckBoxName2.rawValue = 0 // clear checkbox
Regards,
Dave

How can I get values from a checkbox group?

I have been developing a web application with Creator EA 2 and am trying to finish all the functionality before switching to 2. The last thing I have to do is pick up the status of checkboxes that I put in the page with the checkbox group component. Getting stuff from other fields is easy in the code for the page with a statement like: this.fieldname.getText() or ...getValue(). When you enter a line like this, Creator is helpful and gives you the completion choices. I tried some for the checkbox group, but none seem to give me what I want. What I want is the status ( true or false, 0 or 1, ...) for each checkbox in the group. I would appreciate advice on a simple way to get this. Thanks.

You do not necessarily need to bind selected to an array. You might do that if you want to put the array in a session bean, but otherwise, the binding isn't necessary.
Earlier, I provided a link to the Delving into Components tutorials. Here is an excerpt:
"For the items property, you specify a display label and a return value. The selected value returns an array of objects of the same type as the return values. If you use a Default Options component to specify the items and return values, selected returns an array of String objects.
The values in the selected array match the return values of the selected checkboxes."
To illustrate, here is how to get the selected values without binding to an array. In this example, the id for the drop-down list is dropdown1.
    public void prerender() {
        if (checkboxGroup1.getSelected() != null) {
            String str="You selected ";
            String[] userSelections = (String[]) checkboxGroup1.getSelected();
            for (int i=0; i < userSelections.length; i++) {
                str+= userSelections[i] + " ";
            staticText1.setText(str);
    }Hope this helps,
Chris

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.

Binding Checkbox Group to Context with Dictionary Enum (WD for Java)

Hello,
I see no examples in the documentation of binding a Checkbox Group to a context attribute that references a dictionary type with an enumeration. When I do so in NDS, it shows the checkboxes in the layout together with the values defined in the type's enumeration. However, when running the application, nothing comes up.
Any ideas or examples would be most welcome.
Thanks,
Martin

Hi Armin,
Thanks for the reply. I see now that I based my question on an incorrect assumption: I thought at runtime that the WebDynpro runtime populates the node with attribute nodes representing the values in an enumeration, if the attribute references a dictionary enumeration I see now that this is not the case.
(My theory was that if these elements are there, a selection of checkboxes should be obtainable by querying the relevant node in the context).
However, I still think there is a need for a checkbox group UI element that you can map to an attribute which in turn references a dictionary element with an enumeration, on the one hand to be consistent with the design of the other UI elements in WebDynpro, and also to make it easier for developers to produce such components, so that checkbox options don't have to be coded in a checkbox group.
What I'm proposing is that a UI element is needed representing a checkbox group, in which you can reference a dictionary type with enumeration, such that either:
1. The runtime populates attribute nodes in a node in the context with all the available values in the enumeration, and the selected values can be queried at runtime.
OR
2. Depending on the selection, attribute nodes are created inside the node in the context, one for each selected value.
Just to clear up any confusion: I'm not trying to make the existing CheckBoxGroup element do this. I understand this is not possible. That is why I'm saying a new element is needed that can provide this functionality.
Does this make sense?
Thanks and Regards,

Checkbox group and Java Studio Creator 2 EA 2 - MySQL 5.0.16

Hi folks, there is a bug while I try to use the checkbox group linked with a table:
1. I create a form
2. I put some fields in it
3. I put a button that saves the data
I run the application and everything works for the moment
4.I put a checkbox group and the IDE creates automatically a checkboxGroup1DefaultOptions
I run the application and everything works.
5. I link the checkbox group with a table. The table has several fields, Strings and BIGINT(20)
6. The IDE creates automatically a Long converter (checkboxGroup1Converter - javax.faces.convert.Long) because I use the BIGINT type to hold my primary key
I run the application and everything works (I can still update my data except the checkbox group as the code doesn't exist yet)
7. I'll add the code ion the prerender to read the table and reflect the selection of the users on the checkbox group. Check the checkbox group description inside this tutorial http://developers.sun.com/prodtech/javatools/jscreator/ea/jsc2/learning/tutorials/about_components.html
ArrayList mySelectedXXX = new ArrayList();
mySelectedXXX.clear();
while (resultSet.next()) {
mySelectedXXX.add(new Long(resultSet.getLong("id_XXX")));
checkboxGroup1.setSelected(mySelectedXXX);
.....8. I run the application
9. The checkbox group reflects the content of the table
9 I click on the save button
try {
            XXXByIDDataProvider.commitChanges();
            info("Changes saved.") ;
        } catch (Exception ex) {
            log("Error Description", ex);
            error(ex.getMessage());
        return null;10. I receive the following exception. Here is the code that raises this exception.
public LongConverter getCheckboxGroup1Converter() {
        return checkboxGroup1Converter;
Does anyone has an idea about the reason of the bug. I tried to debug line by line but the ConversionUtilities.java does to seem to be reachable by the debugger.
I think that the assignement in the prerender method could be the cause of the problem: ...............
while (resultSet.next()) {
mySelectedXXX.add(new Long(resultSet.getLong("id_XXX")));
checkboxGroup1.setSelected(mySelectedXXX);

Hi Abdelkrim,
Try to place variable ArrayList mySelectedXXX
to SessionBean and change your prerender code to something like that to reflect changes:
//prerenderer method
// you need this check in order to execute this code only first time page is rendered
if (getSessionBean1().getMySelectedXXX() == null) {
    getSessionBean1().setMySelectedXXX(new ArrayList());
    while (resultSet.next()) {
        getSessionBean1().getMySelectedXXX().add(new Long(resultSet.getLong("id_XXX")));
    checkboxGroup1.setSelected(getSessionBean1().getMySelectedXXX());
}Also you'll need to execute getSessionBean1().setMySelectedXXX(null); when you leave the page.

Visual Web JSF: Rendering a checkbox group with some checkboxes preselected

Dear Sirs and Madams,
I am a Visual Web JSF newbie and have been humbled by this one issue: I have User value objects which hold a List attribute of what user privileges they have. Am trying to render a checkbox group of user privileges for a chosen user with some user privileges already checked (the ones the user already has), and some not checked (potential privileges to give to the user) for the EditAUsersPrivileges page. Is this even possible? If so, how?
Profusely thanking you in advance,
Phoenix

Of course, use the value attribute of the component and set it to EL representing the desired property.

Checkbox group selected property binding not working

Hi,
I've been through all the threads and tutorials relating to this problem and none of them help.
The Situation
I have a checkbox group which I have bound the items items property to a MySQL database (value field = int, display field = String). I have bound the Selected property to a sessionbean field which is an int[] array.
I have a processValueChange event for my checkbox group which grabs the selected boxes values (ie the int value of the checkbox id). Based on these values it does some other processing.
The Problem
When the page loads everything is displayed ok. When I select a checkbox within the checkbox group the getSelected() method returns the int value of the selected checkbox and perform other processing as necessary... so far so good.
However, when the page finishes processing and reloads the selected checkboxes are not ticked. I'm sure it has something to do with the Selected property of the checkboxgroup but I can't for the life of me work out why. For multiselect objects the Selected property must be bound to an array which I have done with my int[] array. I've tried preloading the array with default values (1, 2, etc) to mimic the int values from the database. I've tried changing the array to a boolean array but this throws exceptions. So basically i'm stuck.
The Source

ok, i found the problem. MySQL int value is treated as an Integer in Creator. I changed my SessionBean array from int[] to Integer[] and now it works properly... phew!!!

Data into a checkbox group

Hi all,
My conttext is MonthsOfYear--Node
                     MonthName--attribute
here i have to populate checkbox group with values as "Jan","Feb"....."Dec"and display the selected months in to a table....
Wat the problem here is By default Jan is getting selected and getting displayed in table eventhought we select something else than jan it is not getting considered...
the code i used for this is
String[] monthNames = new String []
             "January", "February", "March", "April",
             "May", "June", "July", "August",
             "September", "October", "November", "December",
     List monthsOfYear = new ArrayList();
     for (int i = 0; i < monthNames.length; ++i)
          IPrivateChkView.IMonthsOfYearElement Myear=wdContext.createMonthsOfYearElement();
          Myear.setMonthName(monthNames<i>);
          monthsOfYear.add(Myear);
     wdContext.nodeMonthsOfYear().bind(monthsOfYear);

My guess is that the "initializeLeadSelection" property is set to true for context node "MonthsOfYear". Therefore, the first element in the checkbox group is selected by default. Either unset this property at designtime or clear the lead selection in the controller (e.g. in the wdDoInit method or the supply function of the node).
To keep the table in synch with the selected checkboxes, assign an action to the CheckBoxGroup.onSelect event. In the action handler, update the table data source node according to the selected entries (or invalidate the node and update its elements in a supply function).

WAD 7.0 Checkbox Group web item - ability to select/deselect all

Hello. I am currently using within the Web Application Designer 7.0 the web item Checkbox Group. I would like the ability to add a "select all" and "deselect all" button(s) to select all values and deselect all values respectively.
Has anyone in the community been able to accomplish this? Our user base has asked about this frequently.
Kind regards,
Lynn Peter

Hi,
This can be solved by using a Container layout item and a button group item.
1 Put the Checkbox item and a button group item in the Container layout item.
2 Configure a button in the button group item with the command CLEAR_SELECTION_STATE and connect it to the criteria/key figures you wish to use it on.
3 Configure another button similarely with the command SET_SELECTION STATE. (In our user case this button was not necessary)
4 Configure the Container layout item to display your checkbox and button group as desired.
This should solve your problem, we had exactly the same problem with the before "unfriendly" user interface.
BR,
Niclas

It seems to be a fault in the Woodstock Bacic library - Checkbox Group

Ver. NetBeans IDE ver. 6.5.1
The project is a Visual Web Javaserver Faces.
The example page has the following two components from the Woodstock Basic Library:
- Checkbox Group ( CB )
- Static text. ( ST )
The CB is implemented with "Auto-Submit on Change"
This means that I reads the choice after each change in the CB, and shows the value in the ST. This works fine.
    public void radioButtonGroup1_processValueChange(ValueChangeEvent vce) {
        *this.staticText1.setValue(vce.getNewValue().toString());*
    }The fault is then uncovered when I then choose one of the choices as a default in the CB
private void _init() throws Exception {
        radioButtonGroup1DefaultOptions.setOptions(new com.sun.webui.jsf.model.Option[]{new com.sun.webui.jsf.model.Option("item1", "Item 1"), new com.sun.webui.jsf.model.Option("item2", "Item 2"), new com.sun.webui.jsf.model.Option("item3", "Item 3")});
        *radioButtonGroup1DefaultOptions.setSelectedValue("item2")*;
    }The default choice is then not shown in the ST. I can select the default choice, but nothing is shown in the ST.
The other choices is shown in the ST after a selection.
My company is in a evaulating periode and it's important for me to get this working. It is a basic function.
The CB must me choosen to go further and its a haze to always pick a choice to go further when default value is de-selected.

Hi,
Thanks for giving time craig.mcc
Do you think this code should still work.
<h:selectone_radio id="selectedUser" valueRef="UserInfo.userId">
<h:selectitem valueRef="UserInfo.userId"/>
</h:selectone_radio>
Though panel_data is iterating through the UserInfo and it is also printing radio buttons on each row. But not assigning value to the radio button. And the same in the next line
<h:output_text id="userId" valueRef="UserInfo.userId"/> is printing the value from the UserInfo variable.

Checkbox group. wtf?

Excuse the abbreviation but I just created a large checkbox group to find that no matter how many checboxes I select, just one registers. Like radio buttons. Do checbox groups act like that or might I have done something wrong? I'm trying to avoid having to the entire list all over again because I spent a lot of time on it. Please, please help!

right, sorry about that. here's a smaller section that acts the same
<table width="0">
            <tr>
              <td>
                <label>
                  <input type="checkbox" name="Columns" value="1 column" id="Columns_0" />
                  <span class="smalltext">1 column</span></label></td>
              </tr>
            <tr>

CheckBox Group Get Selected Items

Hi, I have a problem with a CheckBox Group.
I have different items in the CheckBox Group, and I get the items that are selected.
When I do the checkboxgroup.getselected () returns the selected items, but I do not know how to get the values separately.
I tried to do:
ArrayList array = new ArrayList ();
array. add (checkboxgroup.getSelected ());
but in the array.get (0) add all the values. And I need:
array.get (0) -> first value selected checkboxgroup
array.get (1) -> second value selected checkboxgroup
array.get (2) -> third value selected checkboxgroup
Thank's !

Never mind..I got it.
it as simple as that:
Alert.show (lst.selectedItem.fieldname);
