How to handle checkbox in jsf

[saravana kumar]

Hi All,
I am new to JSF framework. I have the following requirement
From the listing screen i have to select one or more record to perform delete operation thru checkbox. Can anyone tell me how to identify the selected records in jsf without using javascript...
Thanks for any help.

Hi,

You will need to be more specific, where are you storing these records? In a datatable?

Hi,
Please loot at the sample code in jsf

<h:dataTable var="adminList" id="mytable" value="#{messageList}" border="1" style="background-color:silver">

<h:column>
<f:facet name="header">
<hutputText value="Select All"/>
</f:facet>
<h:selectBooleanCheckbox value="{adminList.selected}"/>
</h:column>

<h:column>
<f:facet name="header">
<hutputText value="User Id"/>
</f:facet>
<h:commandLink action="#{userManager.editAdmin}" >
<hutputText value="#{adminList.userId}"/>
</h:commandLink>
</h:column>

<h:column>
<f:facet name="header">
<hutputText value="User Name"/>
</f:facet>
<hutputText value="#{adminList.userName}"/>
</h:column>

<h:column>

<hutputText value="Phone Number"/>
</f:facet>
<hutputText value="#{adminList.phoneNumber}"/>
</h:column>

<h:column>

To get this to work i normally bind the data table into my bean and then access the row via the getRowIndex() on that bound in table. e.g.

Add this attribute (and appropriate getter/setter methods) to your bean

private HtmlDataTable messageTable;

then add this to your datatable declaration in the xhtml -

  binding="#{bean.messageTable}"  

now that you have the component bound into your bean, in you action method where you are deleting. you can just do this

 messageList.get(messageTable.getRowIndex());  

Now you have the selected message to delete....

Is this close to what you want to do?
