Where to define this class?
I have a class that I am using for each row in a grid, it is the mix of
multiple entities data. the question is where to put it? I tried placing the
class in the component package and instantiating it within my page, tried
returning the class from an injected service, and nesting the class within
the page POJO. in all cases it will work once and then on refresh I get this
error:
Failure writing parameter 'row' of component admin/Add:grid.rows: Failure
writing parameter 'row' of component admin/Add:grid: Could not find a
coercion from type com.foo.bar.pages.admin.Add$RolesRow to type
com.foo.bar.pages.admin.Add$RolesRow.
here is the class
public static class RolesRow{
@Property public Boolean ROLE_SUPER;
@Property public Boolean ROLE_ADMIN;
@Property public Boolean ROLE_USER;
@Property public Boolean ROLE_VIEW;
@Property public Boolean ROLE_EMAIL;
private Map<String,Role> roles;
public RolesRow(){
}
public RolesRow(Map<String,Role> roles){
ROLE_SUPER = (roles.containsKey("ROLE_SUPER") ? true:false);
ROLE_ADMIN = (roles.containsKey("ROLE_ADMIN") ? true:false);
ROLE_USER = (roles.containsKey("ROLE_USER") ? true:false);
ROLE_VIEW = (roles.containsKey("ROLE_VIEW") ? true:false);
ROLE_EMAIL = (roles.containsKey("ROLE_EMAIL") ? true:false);
this.roles = roles;
}
public List<Role> selected(){
List<Role> r = new ArrayList<Role>();
checked(r,"ROLE_SUPER",ROLE_SUPER);
checked(r,"ROLE_ADMIN",ROLE_ADMIN);
checked(r,"ROLE_USER",ROLE_USER);
checked(r,"ROLE_VIEW",ROLE_VIEW);
checked(r,"ROLE_EMAIL",ROLE_EMAIL);
return r;
}
private void checked(List<Role> r,String field,Boolean obj){
if (obj !=null && obj == true){
r.add(roles.get(field));
}
}
I am instantiating the record in setupRender:
void setupRender(){
List<RolesRow> list = new ArrayList<RolesRow>();
list.add(new RolesRow());

Ahh, makes sense now. I changed all the fields to public because of that
little gotcha.

Are you using it in more than one page? With a tiny view class I
sometimes just stick it right in the page/component that uses it.
Otherwise, like Thiago said, you need to put it in a package that's
not special to tapestry. How about /viewobject or /vo
By the way

This only works in your page and component classes. You'll need to
create your own getter/setters.

Any package that isn't components, pages, mixins or base.
