s:checkbox inside a s:iterator and values in a Integer[]
Hello,
I've browsed nabble, google, ... but can't find a simple example on how to
do something very simple.
I need to iterate through, let's say, a picture category list, showing each
category as a s:checkbox. The picture belongs to some of these categories
(and user can changed that, or course, thanks to the checkboxes), so some of
the checkboxes must be pre-checked. Which of them are checked is shown in a
Integer[] (could be String[] if necesary, no problem). I guessed the right
way to do it is using a String or Integer array as checked values will be
sent to the struts2 action through that same property.
Is it that difficult to use s:checkbox for this? I know how to do it using
s:checkboxlist but can't here as I need special format in the iteration.
For some reason the following:
<s:iterator value="categoryTree">
<s:checkbox labelposition="right" name="categoryId" fieldValue="%{id}"
label="%{name}"/>
</s:iterator>
(categoryId is a Integer[] having which id values should be checked but all
checkboxes appear as checked)
For some reason I've found more people with this same problem but they got
no answers. Thanks for any example or ideas if I must change the way
pre-checked data is got from the action.
Ignacio

Thanks a lot for reply. It works OK that way. I had to make a getter for the
Category objects as a List and maintain the setter for the categoryId
Integer array. It would be great if s:checkbox could also check when to
pre-check the checkbox in the same way as s:checkboxlist does (I think I
used s:checkboxlist getting checked fields from the Integer[] id getter. It
makes sense to use the same property to get checkbox status and to set
checkbox status)
Anyway, thanks a lot for your example.

Re: s:checkbox inside a s:iterator and values in a Integer[]
Posted by Musachy Barroso <mu...@gmail.com>.
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="%{possibleValues}">
<s:checkbox name="categoryId" fieldValue="%{id}"
value="%{#selectedValues.contains(top)}" />
</s:iterator>
