Re: Struts2 Checkboxlist
I think the issue I am having is due to the theme, I had old checkboxlist.ftl
code. Once it is updated to the latest code it is working well. The only change
I make in it is show each checkbox in a
separate line.
Appreciate all the help.
Thanks,
Prasanth

Re: Struts2 Checkboxlist
So there is no need to add MultiselectInterceptor in the action definition?
Below is the checkboxlist in the jsp. accountNames map is in the account to
provide the list values and names.

RE: Struts2 Checkboxlist
Ach! Sorry, you're right. For checkbox list it's MultiselectInterceptor class
which handles this and here it works with following config:
List selectedLongs= new ArrayList<>();
public List getLongs(){
List longs= new ArrayList<>();
longs.add(0L);
longs.add(1L);
return longs;
}
public void setSelectedLongs(List selectedLongs){
this.selectedLongs = selectedLongs;
}
public List getSelectedLongs(){
return selectedLongs;
}
/WEB-INF/tags/ui/exampleSubmited.jsp
/WEB-INF/tags/ui/example.jsp
When I post an empty form, MultiselectInterceptor adds an empty string for
selectedLongs http param, then Struts internal conversion converts it to an
empty instance of List, then setSelectedLongs will be called here with it.

Hi Yasser, Even after having the param the ArrayList was not populated with -1 for unchecked checkboxes. The ArrayList is in form.

Re: Struts2 Checkboxlist
I am using the defaultStack but the ArrayList used for the checkboxes is of type Long. If we change it to ArrayList of Boolean would the interceptor set the values to false? Or is this only applicable if you have individual checkboxes rather than checkboxlist?

RE: Struts2 Checkboxlist
Yes, setFoo is only called if the checkbox is checked. However, Struts 2 does have a checkbox interceptor: https://struts.apache.org/core-developers/checkbox-interceptor.html This interceptor defaults checkbox Boolean's to False if the box is not checked. This is part of the default interceptor stack.

Hi Yasser, When none of the checkboxes is selected the setFoo is not getting called.

RE: Struts2 Checkboxlist
Hi Prasanth, AFAIK this tag is like this: It calls getBar method of your action or finds bar in value stack to find out what to display. Same for baz to find out which to be selected. Then it calls yourAction.setFoo to post selected items. i.e. it is up to you what you do with it in setFoo method. Normally you should clear baz and fill it with them again to update selected items. Thanks for using Struts!

Re: Struts2 Checkboxlist
The data class holding the array is in session, done using the scope interceptor.

Re: Struts2 Checkboxlist
Hi, As I understand, you need to modify previous Array before saving. Have you tried Session variable ?

Re: [Struts2] CheckBoxList returns XWorkList instead of ArrayList
Yeah, you can chalk this one up as a "duh" moment for me. I'm using the
Db4o object database to save my objects, and it was erroring out when I was
trying to save an ArrayList retrieved from the form, (but Struts2
was returning an XWorkList instead). Struts is just doing what it should
be, and I think my Db4o code is in error.
Thanks for the replies...

Isn't XWorkList a sub-class of ArrayList?
