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.

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
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.
