Re: Struts2 Dynamic Checkboxes
Ah, I am such a dingbat... the beans in my list contained a property
with the same name as I used for the Collection property in the backing
bean. So when the tag was checking if the option was there or not it was
looking at some boolean property of that bean instead into the Collection.
Not before I downloaded the Struts2 source and debugged the
ListUIBean.compare() method I realized that ;-)
So this answers my question, and I am happy to say that my dynamic
checkboxes now work perfectly!

I think I found an OK solution but one thing does not work and I don't
understand why.
So what I am doing is creating single checkboxes in an iterator,
disabling the automatically generated label through a modified simple
theme and creating my custom labels:
s:iterator value=cars
s:label
s:checkboxlist templateDir=template
template=checkboxlist.ftl
theme=nolabel
name=car
list=%{''+name}/
s:text
name=format.moneyrounds:param value=price//s:text
s:property value=name/
/s:label
/s:iterator
cars is a List of simple beans with, among other, a name property.
The car property is a Collection. When I check a checkbox and submit
the form, I can see that an XWorkList containing the value is passed to
setCar().
BUT: When the form is redisplayed, as because of a validation error, the
getCar() method is not called and the checkbox is not checked.
Can anyone tell me why?
If I move the s:checkboxlist tag outside the s:iterator, it works,
but like this I can't create my custom labels, which is what this is all
about...

Oh, I don't know about that.
You could use a map (or list) for the checkbox values
and gather up the result values that way, couldn't
you?
You just need to pre-populate the map (or list) in the
action before hitting the view.

Re: Struts2 Dynamic Checkboxes
I have been struggling with the very same problem. So you say pre-populate the map/list. Would you make that a separate data structure, or part of the object already being passed? Let's say it's separate, just add the Map/List to the action, create setter and getters, and make sure and recreate the list when ever a function of the action is called that returns to the page where you display the list and the choices?

Re: Struts2 Dynamic Checkboxes
It sure does and I already looked at it, but I was trying to create single checkboxes in an s:iterator in order to be able to put them in a custom layout. I kind of have the same problem with radiobuttons so I guess I should reconsider my design so I can use the default markup and thus the tags as they are supposed to be used... I see there is no point in what I am trying to do. Thanks!
