Re: Java templates s:checkboxlist tag and the significance of parameters.nameValue
Thank you Mauricio. I appreciate your help. If that is a bug though, is there a possibility of using Java templetes engine for some tags or pages and FM engine for others?

Problem with s:checkboxlist, FreeMarker template Error
Hello list!! I'm having a problema with this tag, I don't know what to do :(
I hope you guys could help me.
As here says http://struts.apache.org/2.2.3/docs/checkboxlist.html I can use
a Map object in the list attribute of a checkboxlist, When i go for it I got
this FreeMarker template error:

Even weirder, when I use a List object (because, i don't know, maybe List
would work), I also get the same error!
I don't know if this is a bug or I am doing something wrong. In the action
class I define a MapInteger,String objected implemented as HashMap, and
ListString as ArrayList, I dont' even know what freemarker is :(
Thank you for your help

s:checkboxlist and the CheckBox Interceptor
The documentation says that the checkbox interceptor Looks for a hidden identification field that specifies the original value of the checkbox. If the checkbox isn't submitted, insert it into the parameters as if it was with the value of 'false'. Should the interceptor work with s:checkboxlist or does it only work with s:checkbox. All I'm getting back from the s:checkboxlist is a list of selected checkboxes, there's no indication of any that are unselected. Given the trouble I've been having with the s:checkboxlist tag recently I thought I'd ask before I dive in.

Re: s:checkboxlist and the CheckBox Interceptor

If the checkbox isn't submitted, insert it into the parameters as if it was with the value of 'false'. So let's think about how that works: If a form includes input type=checkbox name=foo value=true / then the browser either includes foo=true as a parameter or does not. The checkbox tag also causes the form to include input type=hidden name=__checkbox_foo value=true / . When the interceptor runs, if it sees a value for __checkbox_foo but none for foo then it knows the checkbox was not checked and can add as a request parameter the field foo with the appropriate value for a non-checked checkbox. Should the interceptor work withs:checkboxlist or does it only work with s:checkbox. All I'm getting back from thes:checkboxlist is a list of selected checkboxes, there's no indication of any that are unselected. When you're including in the form a bunch of checkboxes with the same name attribute, the browser will submit those that were checked and not submit anything for those that were not. Since they all get submitted with the same name, I can think of no simple way for the server to distinguish between them, or thus detect which checkboxes were not submitted (which would then enable the interceptor to decide which hidden fields need to be introduced into the parameter set. Given the trouble I've been having with thes:checkboxlist tag recently I thought I'd ask before I dive in. I could be wrong about this -- I've not used the checkboxlist tag myself, and have not read any documentation before writing this response -- I'm just providing my gut reaction on how the underlying html form mechanisms mean the same checkbox solution would not work easily if the checkbox's name were not unique. Maybe another solution has been figured out and implemented already. For example, if there were a set of hidden fields corresponding to the checkboxes, it might be possible to figure out which of those values were not included in those submitted by the checkboxes, and set some other request parameters to match (so you could end up with a list of checked values (setFoo(ListString)) and a list of unchecked values (setNotFoo(ListString))). I'd look in the documentation, the .ftl files implementing the checkboxlist tag to see if there are any useful hidden fields included in the form, and the interceptor code to see exactly what it does (especially when multiple request parameters have the same name). -Dale - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
s:checkboxlist help
s:checkboxlist list=#{0:'',1:'',2:''} name=user
label=%{getText('com.upasana.type.'+toString())}/s:checkboxlist
But the key value is not passed to getText()
The idea is to just initialize the keys in the checkboxlist and fetch the
corresponding display text from .properties file
Thanks in advance
Re: s:checkboxlist help
Hi,
the label attribute is only used to render the label of the group of
checkboxes. It is not used in an iterative way. In order to access to
your .properties file, you have to build your list in your action then
give it in list attribute.

their values will be put into an array or collection action property.
For a checkbox w/ a true/false value probably need either an index or to use a

Re: s:checkboxlist or s:checkbox
tks very much, it works after change var to id.
Also, have further question need to bother you similar to it
same bean class
public class Bed {
private String bed_id;
public String getBed_id() {return bed_id;}
public void setBed_id(String bed_id) { this.bed_id=bed_id; }
}
same action class
...
private ArrayListBed beds;
public String execute() throws Exception {
beds=service.Beds();
return SUCCESS;
}
public void setBeds(ArrayListBed beds){ this.beds = beds; }
public ArrayListBed getBeds() { return beds; }
almost same jsp file
s:iterator value=beds status=st
s:property value=bed_id/
/s:iterator
s:select label=Bed ID name=bed_id headerKey=1 headerValue=Please
Select Bed# list=beds/ /* the problem */
the output is
1 2 3 4
...@188d92e
...@16a5bcb
b...@1b08cf3
@1f5d699
my question is that why s:select list print object but value, is because i
defined ArrayListBed ?
what is the correct way to fetch value out as s:iterators:property
value=bed_id/ did

Re: s:checkboxlist or s:checkbox
I'm jumping in a bit late, but I'll add a few observations. I don't think that
execute is the place where you want to initialize your service and populate
the beds list... You're better off implementing Preparable and initializing
the list there.
Second, when you are using the iterator and creating single checkboxes, you
need to make the names unique. You are simply creating a new checkbox with the

Preparable will run per invocation, just like execute runs once per

second, as your suggest, i need to change the name, but how?
Really, implementing Preparable and moving the initialization logic to a
prepare method is your best option. But, what you have to do to make your
checkboxes unique is add some OGNL like this -
s:iterator value=beds status=st var=curBed
s:checkbox name=%{'bed[' + (st.count -1) + ']'
value=#curBed.bed_id/s:checkbox
/s:iterator
Now, that code is completely untested and the status object's count member is
1-based, not zero-based as you'll need since you're iterating an ArrayList,
that's why there is some math in there. I can't remember if you can do it that
way or if you'll just end up with string concatenations... but you get the
idea. You could also get done and find the object uninitialized since your
logic for loading up the arraylist is done in the execute method.

I'm jumping in a bit late, but I'll add a few observations. I don't think
that execute is the place where you want to initialize your service and
populate the beds list... You're better off implementing Preparable and
initializing the list there.
Second, when you are using the iterator and creating single checkboxes, you
need to make the names unique. You are simply creating a new checkbox with
the name beds over and over again.

For a checkbox w/ a true/false value probably need either an index or to use a map-based property.

s:radio and s:checkboxlist - how to customize listValue property.
When I use that 2 components in my form I need to set attributes listValue and listKey. That attributes as I understand require a field of a bean that is a member of collection represented by list attribute. Example: s:radio list=types name=type label=Type listValue=name listKey=id / That means: 1) there will be one radiobutton for each element of collection getTypes(). 2) Each html radiobutton will have value = getId() and label = getName() . I want to compose label from several fields of my bean. So I can't write s:radio listValue=someField / because that class doesn't have getSomeField() method.

Re: s:radio and s:checkboxlist - how to customize listValue property.
The easiest (I'm not going to say best) solution is to make a fake getter on your bean. Make a getListLabel() method that composes a String from the values that you want to display in the list label, and then set the listValue to be listLabel. This is the way I've done this in the past and it works OK. It isn't ideal if you want to keep your model carefully isolated from your UI but my own designs are a little less pure than that. jk On Wed, Mar 11, 2009 at 10:05 AM, boraldo bora...@hotbox.ru wrote: When I use that 2 components in my form I need to set attributes listValue and listKey.

}Hallo,
is there any way to set that all items (checkboxes) in
s:checkboxlist are in their own line, one checkbox under other.
Defaultly they are all on the same line and I cannot find the way
how to set that each one checkbox has to have their own line :-(
Thanks, Jiri
Re: s:checkboxlist
The way I solved this was to add my own theme, and change the xhtml theme's
checkboxlist template to match what I wanted 'my' checkboxlist to do.
Under the root of your web app, add a directory named template. Under
template add a directory called myapp. Then copy checkboxlist.ftl out
of the Struts jar into template/myapp, and modify it as you wish. Finally,
in your JSP, do s:checkboxlist theme=myapp .../
This comes up fairly often -- I am happy to add it to the FAQ if someone can
tell me how I do that.

s:radio/s:checkboxlist and primitive properties
I tried to use primitive types/arrays of primitives as name property of s:radio and s:checkboxlist. It works fine, but the state is not maintained because the ContainUtil.compare() method returns false as it compares e.g. an Integer and a Sting using Object.equals(). Is there a reason why we can't use primitives like in for example s:checkbox? I patched my own ContainUtil.compare() and it seems to work fine now - should I log a JIRA issue/RFE?

[S2] s:iterator and s:checkboxlist inside (using 2.0.2 trunk)
Hi,
I have such properties in my action:
private ArrayListExtension extensionGroups = null;
private HashMapString, ArrayListExtension groupedExtensions = null;
The 1st list contains only some 'Extension' elements.
The 2nd map contains other lists of extensions (values) with some
property (treeNo) from the parent used as the key.
Then I have a JSP page with such construct somewhere in it:
s:iterator value=extensionGroups
b${desc}/bbr /
s:checkboxlist
list=groupedExtensions['${treeNo}']
listKey=name
listValue=desc
name=extensions
labelposition=right
/
/s:iterator
And here is a strange thing:
When I start the app and run the action for the 1st time I get nice
result AS EXPECTED:
GROUP1
chk: extension1
chk: extension2
chk: extension3
GROUP2
chk: extension4
chk: extension5
But after reloading the page (no extra params in the url, just plain
GET), the result is:
chk: GROUP1
chk: GROUP2
Looks like the context of the data beaing displayed is different.
But it's the same page! The same code and the same data.
After restarting the app it is again the same behaviour.
My debugs in the actions (getters) show that the same data is returned
in all cases.
What am I doing wrong?

Re: [S2] s:iterator and s:checkboxlist inside (using 2.0.2 trunk)
I have found a solution after lots of experiments.
I am still not sure what caused the problems (I tried tons of variants
in the JSP) but finally it started to work. No changes in the action
code, only in the JSP block.
It started to work after I added jstl into the game and dropped the
s:iterate tag.
s:set name=groups value=extensionGroups /
c:forEach items=${groups} var=group
b${group.desc}/bbr /
s:checkboxlist
list=groupedExtensions['${group.treeNo}']
listKey=name
listValue=desc
name=extensions
labelposition=right
/
/c:forEach
Can somebody say what caused problems in the previous code I have sent?
Why did it work on the 1st invocation and failed on all other calls?
