Hello.
I an trying to use the ListMultipleChoice and want to use my list of custom
Authority object as options. The form is shown correctly with the right
options and values and everything.
The problem arises when I submit the form. For some reason the selected
values are not converted correctly to the array of Authority objects that I
defined in my User class.
The message I get is:
WicketMessage: Can't convert value: [ROLE_ADMIN, ROLE_ADVANCED, ROLE_USER]
to class: class [Lcom.tripolis.common.domain.security.Authority; for setting
it on (object's toString() method value)
I tried various convert methods and implementing an IConverter in the
getConverter method but nothing worked. Can someone let me in on the big
secret here?
My User class is:
private Authority[] permissions;
...
public void setPermissions(Authority[] permissions) {
this.permissions = permissions;
}
public Authority[] getPermissions() {
return permissions;
}
My form is:
ListMultipleChoice dropdown = new
AuthorityListMultipleChoice("permissions",
Authority.findRolesBySecurityLevels(Authority.SECURITYLEVEL_PARTNER,
Authority.SECURITYLEVEL_APPLICATION, Authority.SECURITYLEVEL_API)
);
add(dropdown);
dropdown.setRequired(true);
...
// inner class
private final class AuthorityListMultipleChoice extends
ListMultipleChoice
{
public AuthorityListMultipleChoice(String id, List<Authority>
authorities)
{
super(id, authorities, new ChoiceRenderer() {
@Override
public Object getDisplayValue(Object object) {
return ((Authority)
object).getAuthority(); // returns the string
value
}
@Override
public String getIdValue(Object object, int
index) {
return ((Authority)
object).getAuthority(); // returns the string
value
}
});
}
}
