Checkboxgroup

Can anybody please guide me for runtime binding of checked property of checkbox group ?
I have a group of checkbox. I want to set checked property of that checkbox at runtime with the help of context variable . can any body give me proper code snippest for the same ?

There is no property named "checked".
Bind the "texts" property to a context attribute inside a node (cardinality 0:N, selection 0:N). Node elements will represent the check boxes, a check box is selected if the corresponding element is (multi-)selected in the node.
See also Javadoc:
The CheckBoxGroup UI element represents a multiple selection visualized as a group of checkboxes.
Data binding:
The property texts must be bound to an attribute Text living in a context node Values of cardinality 0..n and selection 0..n. The attribute Text must have a simple type like String.
The number of checkboxes is the size of node Values. The displayed texts are the values of attribute Text and the selection is the (multiple) selection of node Values. The check boxes are arranged into rows, the size of each row is limited by property colCount.
Events:
If a checkbox is toggled, the event onToggle is triggered. Event parameter checked contains the new state of the checkbox, property index contains the index of the toggled checkbox.

Getting selected values from checkboxgroup in jsf

Hello,I am making a jsf project and I am new in this kind of project.I am using a tabset with 2 tabs.In each tab I have inserted a checkboxgroup.Each checkboxgroup is bound with data from a table in my database. What I want is to get the selected checkboxes and according to the selected checkboxes I want to get some data from the database using queries.How do I get the selected values and where do I put the code?

There is a dedicated subforum for JSF. Can you please post your future JSF related topics there? http://forum.java.sun.com/forum.jspa?forumID=427

By a coincidence I have posted a complete example in a topic here: http://forum.java.sun.com/thread.jspa?threadID=5241624 (see reply 10). You can safely remove and keep away the converter if the value type is String or any Number.

Posting values from a table into checkboxes in a checkboxgroup

Here is my situation.
I have a table I am reading into my web dynpro. There are five fields, each may or may not contain an 'X'.
I have a checkboxgroup in my web dynpro. What I need to do is read field one, and if it is 'X', set the first checkbox in the group to true. Then do the same with the other four fields. I am using a checkbox group because I am reading the labels for the fields from an existing table.
I am have not used a checkboxgroup so this is new to me. Can anyone provide some code examples I can use to get my head around this?
Thanks in advance.

Hi,
See the help here. [http://help.sap.com/saphelp_nw70ehp1/helpdata/en/cd/ad884118aa1709e10000000a155106/content.htm|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/cd/ad884118aa1709e10000000a155106/content.htm]
See the example component as described on the help page.
Basically you need a context-node of cardinality 0..n. The number of element in the node represents number of checkboxes in the group.
bind the enabled property based on the value X from the table column.

Problem displaying CheckboxGroup on JFrame

I was recently assigned the task of creating exams. I am trying to create a CheckboxGroup in a class that was passed the Graphics2D tool. This code compiles with no errors when I call it's method:
setLayout(new GridLayout(1, 5));
          CheckboxGroup cbg = new CheckboxGroup();
          add(new Checkbox("Never", cbg, false));
          add(new Checkbox("Almost Never", cbg, false));
          add(new Checkbox("Sometimes", cbg, false));
          add(new Checkbox("Almost All The Time", cbg, false));
          add(new Checkbox("All The Time", cbg, false));
but nothing displays on my JFrame, I tried to draw it with this line(g2 is my Graphics2D tool):
g2.draw(cbg);
but I get an error when compiling that says draw doesn't work. Am I totally off-track with this or is there a simple Graphics2D method that I use to draw this CheckboxGroup?

Conversion error in checkboxgroup component.....

hi
i have a checkboxgroup component. first time when i go this particular page no validation error occurs. but when i go to a different page and return back conversion error occurs in that component.
getSubmittedValue() method for that component returns some value when error occurs.
can anyone give some suggestions to resolve the error. or suggestions on the value to be converted for checkboxgroup

the actual code is
<cg:checkboxGroup binding="#{view$UsersSMSReport.action_chkbxgrp}" columns="1" id="action_chkbxgrp" style="width: 100%;"/>
<cg:message binding="#{view$UsersSMSReport.action_msg}" for="action_chkbxgrp" id="action_msg"/>
where cg is the our own tag discriptor file
we use jsp-api.jar and jstl.jar for customization of components.
the taglib file for this tag refers to class
CGCheckboxGroupTag extends UIComponentTag
the setProperties method in above class contains code for convertor
if(converter != null)
if(isValueReference(converter))
javax.faces.el.ValueBinding _vb = getFacesContext().getApplication().createValueBinding(converter);
component.setValueBinding("converter", vb);
} else
javax.faces.convert.Converter _converter = FacesContext.getCurrentInstance().getApplication().createConverter(converter);
component.getAttributes().put("converter", converter);
the design time class for this component is
CGCheckboxGroupBeanInfoBase extends SimpleBeanInfo
they are compiled into a tld file and added as complib file in project
the same component sometimes i get conversion error in validation phase and sometimes i get error in page displaying
java.lang.NullPointerException
ClassName:com.sun.rave.web.ui.util.ConversionUtilities

CheckBoxGroup, checkBoxOption and netui-data:repeater

Greetings,
How can I have multiple options (<netui:checkBoxOption>) inside a checkbox group (<netui:checkBoxGroup>) dinamycally, using netui tags?
CheckBoxOption doesn't allow using another tag like <netui-data:repeater> as it's parent.
I really appreciate any help.
Mariano

Tim,
I had a similar issue and I could not find a way via the start index and end index
as you would expect.
However, what you can do is write a method in your JPF and access it via <netui-data:choiceMethod...>
tag.Disdavntage being the repeater tag would still loop through rthe entire set,
but would display only what you want.
<netui-data:repeaterItem>
<netui-data:choiceMethod object="{pageFlow}" method="isLineCounterMaxed">
<netui-data:methodParameter value="{container.index}"/>
<netui-data:methodParameter value="{pageContext.lastLineNumber}"/>
</netui-data:choiceMethod>
<netui-data:choice value="true">
........DIsplay Your Data Here.......
</netui-data:choice >
</netui-data:repeaterItem>
Thanks

I'm running into this same issue. Checkboxes work fine but when they are in a checkboxgroup they don't work. Here is what I am using:
<region
 jcr:primaryType="cq:Widget"
 fieldLabel="Region"
 fieldDescription="Check all that apply"
 columns="{Long}10"
 xtype="checkboxgroup">
 <items jcr:primaryType="cq:WidgetCollection">
 <isUS
 jcr:primaryType="cq:Widget"
 boxLabel="US"
 name="./jcr:content/isUS"
 inputValue="on"
 xtype="checkbox"
 checked="checked" />
 <isEurope
 jcr:primaryType="cq:Widget"
 boxLabel="Europe"
 inputValue="on"
 name="./jcr:content/isEurope"
 xtype="checkbox" />
 </items>
</region>
<isExclusive
 jcr:primaryType="cq:Widget"
 fieldLabel="Is Exclusive?"
 boxLabel="Yes"
 inputValue="on"
 name="./jcr:content/isExclusive"
 xtype="checkbox" />
Were you able to find a fix?

Using CheckBoxGroup with in Datarepeater

Hello BEA Experts,
I ahev seen many examples of using the checkbox with in the repeater tag but is there a way to use the checkboxgroup tag with in the repeater item, I am using it as follows , can you let me know if its correct..
Thanks Experts!
Bob
<netui-data:repeaterItem>
<tr class="tablebody">
<td>
<netui:checkBoxGroup dataSource="{pageFlow.nodeIds}">
<netui:checkBoxOption value="{container.item.nodeId}">&nbsp
</netui:checkBoxOption>
</netui:checkBoxGroup>
</netui-data:repeaterItem>

It definitely does not work for ordinary property lists.
To do this with property lists:
repeat with x := 1 to Listcount(pList)
prop := PropertyAtIndex(pList, x)
val := ValueAtIndex(pList, x)
--do stuff
end repeat

Setting the CheckBoxGroup column width

Hello guys
I'm using the IWDCheckBoxGroup UI element to display a list of items in my WD application.
It is working fine, but the project designer asked me, to set it width to 100%, to fill all the screen width ( that is inside a EP IView )
My problem is: I'm using 3 columns and it does'nt respect the proportion (33%,33%,33%). Put all the columns agrouped in the left ( or center ) is not an option
Is there any way to set the columns width in the CheckboxGroup?
Thanks

Tks for your answer, but it didn't solve my problem.
I need to use 100% becouse my checkboxgroup MUST to fill all the page width. My problem as I said is that I don't know how to set the width of the columns. I'm using 3 columns in my checkboxgroup and its widht becomes diferent in runtime.
To create proportional widths I think that I need to set it own width, not the width of the group.
Is it possible? I read the API and didn't find any references about this
Tks again

CheckBoxGroup - Not Getting Created

hi all,
iam new to Web DynPro, kindly let me know to create a CheckBoxGroup. iam not able to create one following the help material in help.sap.com.
thanks in advance
regards,
ajay

Hi Ajay,
1. Create a context node "Month" and attribute under it "monthName"
set Selection Cardinality- 0..n for Month node
2. Create a CheckBoxGroup UI element into your view and assign "texts" =Month.monthName by selecting context attribute.
3. In wdInit() write this code
String[] monthNames = new String []
 "January", "February", "March", "April",
 "May", "June", "July", "August",
 "September", "October", "November", "December",
// 1. Create context elements for node "MonthsOfYear"
 List monthsOfYear = new ArrayList();
 for (int i = 0; i < monthNames.length; ++i)
 IPrivatePcdTreeView.IMonthElement month = wdContext.createMonthElement();
 month.setMonthName(monthNames);
 monthsOfYear.add(month);
// 2. Bind node to element list
 wdContext.nodeMonth().bind(monthsOfYear);
 // 3. Initialize selection
 //select 2 nd month
 wdContext.nodeMonth().setSelected(1,true);
// set lead selection
 wdContext.nodeMonth().setLeadSelection(5);
hope this will work

Rajeev

CheckBoxGroup defaultValue doesn't work

WLW 8.1 sp4
Here's what I have setup:
<netui:checkBoxGroup dataSource="{actionForm.fields}"
optionsDataSource="{pageFlow.possibleFields}"
defaultValue="{pageFlow.sessionForm.fields}"/>
// debug - to make sure pageFlow.sessionForm.fields (type String[]) is properly populated by submits
<netui-data:repeater dataSource="{pageFlow.sessionForm.fields}">
<netui:label value="{container.item}" />,
</netui-data:repeater>The check box group are rendered correctly.
On submit, they populate the String[] field in session form correctly.
However, the defaultValue array does not pre-select the check boxes on the browser.

defaultValue attribute will not take effect AT ALL if the field is a select box, and allowNull is set to true.
That is, when the form bean field is null, null is a valid value and thus defaultValue attribute is ignored.

How to know CheckBoxGroup element checked or not

Hi Friends,
 I am working on the webdynpro programming and now i got a problem in checkboxgroup.
 I need to know whether a checkbox element in the checkboxgroup is checked or not.
 Based on that i need to dispaly the text of that checkbox element.
 I got the solution to display the text of the checkbox element.But i was unable to place the condition whether that particular checkbox element is checked or not.
 Could you people look in to this problem and hope bright answer from you.

Hi Sandeep,
There is a onToggle event which you can catch. So you can set what function you want to create on the selection of the checkBox.
It returns a boolean value. Initial value is set to False. So if the checkbox is checked it returns true. you can check for this boolean value in a if(), function and perform whatever function you want to do here in this loop.
I hope this helps you.
Regards
Pravesh
PS: Kindly consider rewarding points if helpful and solved.

Checkboxgroup setSelected() problem

Hi,
I have a number items read from a .txt file into a checkboxGroup. I have problem in selecting some of them automatically. Please help me in setSelected() function code:
//get selected automatically
 try {
 int numOfLines2 = 0;
 int count2=0;
 String theLine2 = null;
 FileReader fr4 = new FileReader("C:/CreatorProjects/Npad_PAIRS_NLP.prs");
 BufferedReader br4 = new BufferedReader(fr4);
 while ((theLine2 = br4.readLine()) != null) {
 numOfLines2++;
 fr4.close(); // close the file.
 br4.close(); // close the buffer
 FileReader fr5 = new FileReader("C:/CreatorProjects/Npad_PAIRS_NLP.prs");
 BufferedReader br5 = new BufferedReader(fr5);
 listPatientdata = new com.sun.rave.web.ui.model.Option[numOfLines2];
 while ((theLine2 = br5.readLine()) != null || count2 <= numOfLines2) {
 listPatientdata[count2] = new Option(theLine2, theLine2);
 if(count2<=ptftrs) //ptftrs is predefined integer
 checkboxGroup1.setSelected(theLine2);
 count2++;
 } catch(Exception e) {
 e.printStackTrace();
 }I have no problem in using the code if I want all boxes unselected initially.
thanks in advance.
dr.am.mohan rao

while ((theLine2 = br5.readLine()) != null || count2 <= numOfLines2) {
listPatientdata[count2] = new Option(theLine2, theLine2);
if(count2<=ptftrs) //ptftrs is predefined integer
checkboxGroup1.setSelected(theLine2);
count2++;
} catch(Exception e) {
e.printStackTrace(); My guess is to call setSelected after adding all options to check box group. Try something like:
String valueToSelect = null;
while((theLine2 = br5.readLine()) != null || count <= numOfLines2) {
listPatientdata[count2] = new Option(theLine2, theLine2);
if(count2 <= ptftrs)
valueToSelect = theLine2;
count2++;
checkboxGroup1.setSelected(valueToSelect);best regards
