Question

I have a JSF template (xhtml) and I have some checkboxes. But then the page loads I need check boxes to be checked.
Here is my code:

<h:selectManyCheckbox
                  layout="pageDirection"
                  required="true"
                  value="#{myBean.values}">
<f:selectItem itemValue="v1" itemLabel="l1"/>
<f:selectItem itemValue="v2" itemLabel="l2"/>
<f:selectItem itemValue="v3" itemLabel="l3"/>
<f:selectItem itemValue="v4" itemLabel="l4"/>
<f:selectItem itemValue="v5" itemLabel="l5"/>
</h:selectManyCheckbox>

How can I make the checkboxes to be selected when page is loaded? I can find any tags in JSF that specifies checkbox to be checked.

Answer 1

In your code, #{myBean.values} holds the selected values (the checked checkboxes in this case). So you must make sure that myBean.values contains the itemValue items of the selectItems you want to see checked. For example:

<h:selectManyCheckbox value="#{myBean.values}">
    <f:selectItem itemValue="v1" itemLabel="l1"/>
    <f:selectItem itemValue="v2" itemLabel="l2"/>
</h:selectManyCheckbox>

In the above, populate myBean.values with "v1" and "v2" to show them as checked.
