Thank you for the help.
But I could not get it to work.
Here is a code sample from the Action Class:
....
private Set<TraegerPermission> traegerPermissions;
....
The class TraegerPermissions itself have another collection:
....
private Collection<EinrichtungPermission> einrichtungen;
....
And both TraegerPermission and EinrichtungPermission define the
appropriate getter and setter methods for the id, number, name and
writepermission properties?
In jsp I have successful read access:
....
<s:iterator value="traegerPermissions" id="item">
[...]
<s:checkbox ... name="writepermission" ... value="%{writePermission}"/>
[...]
<s:iterator value="%{einrichtungen}">
[...]
<s:checkbox ... name="writePermission" ...
value="%{writePermission}"/>
In neither case are you binding the checkbox input fields to the
underlying model. You need to change the 'name' attributes to fully
dereference the model property so Struts knows where to store the
submitted values. Something like this (untested):
<s:iterator value="traegerPermissions" index="i1">
<s:checkbox name="traegerPermissions[i1.index]" .../>
<s:iterator value="einrichtungen" index="i2">
<s:checkbox
name="traegerPermissions[i1.index].einrichtungen[i2.index]" .../>
Take a look at the various example applications, as the above may not be
exactly right (that's just off the top of my head).

what shall I save in order to can write back changes in the Checkboxes
to the model by struts2 out of box approach?
I tries several settings without success ...
thank you,

Provided the checkbox is properly bound to the collection entry, yes.
You need to specify the name of the s:checkbox (or any other input type)
as userCollection[index].userProperty where 'userCollection' is the name
of the Collection property on your action, index comes from the iterator
and userProperty is the property to bind to.

Thank you for reply!
I just wonder:
I understand it would work out of box for 1 User-Object, if I bound
checkbox
to permission property of this user.
But I wonder it should work out of box if I use (as I described)
Collection
of Users in Action
and on jsp side iterator tag, and checkbox tag within iterator is bound
to
permission properties of users in the iterated Collection.
This does not matter, it should work the same as for single user object?
Thank you,

Hello,
I have the following problem:
in action i have a collection of class User
each class User have different attributes, one is: boolean permission
in JSP I use struts 2 iterator tag to iterate the User Objects.
For each User entry I create one row in table.
for displaying/changing the boolean permission value I use S2 checkbox
tag
so far it works fine and show all data in collection of Users correct.
But how can I set changed checkbox values (the permission attribute)
back
to
action?
If your checkbox is bound the the permission property of the user,
submitting the form should update the property. If that's not happening,
you need to give more details: what your JSP code looks like, and the
relevant bits of your action and User code, at least.
