you need to specify the "value" attribute, which is the one that will
make it checked or not, for example, assume "possibleValues" is the
list of possible values, and "selectedValues" is the list of currently
selected values, and both lists contain objects that have an int "id"
field (same type of objects):

<s:iterator value=3D"%{possibleValues}">
<s:checkbox name=3D"categoryId" fieldValue=3D"%{id}"
value=3D"%{#selectedValues.contains(top)}" />
</s:iterator>
