Hello,
I'm stuck in my head, here's my tiny little problem: I want to submit
a list of Long values to an action bean. These values are database
ids, so i want them encrypted. The following solution is giving me
NullPointer exceptions in the TypeConverter. The generated Link is not
looking like I'd expect it to look:
/app/administration/ConsultantRoles.htm?consultantId=sN4P-XQFPKw%3D&assignedRoleIds%5B0%5D=1
This is the sourceCode:
ConsultantRolesActionBean:
private List<Long> selectedIds;
public ConsultantRolesActionBean() {
assignedRoleIds = new ArrayList<Long>();
}
@ValidateNestedProperties(
{ @Validate(on = "view", encrypted = true) })
public void setAssignedRoleIds(List<Long> assignedRoleIds) {
this.assignedRoleIds = assignedRoleIds;
}
jsp:
<s:url var="assignRolesUrl"
beanclass="xyz.controller.app.administration.ConsultantRolesActionBean">
<s:param name="consultantId" value="${consultant.id}"/>
<c:forEach var="role" items="${consultant.assignedRoles}"
varStatus="rolesStatus">
<s:param name="assignedRoleIds[${rolesStatus.index}]"
value="${role.id}"/>
</c:forEach>
</s:url>
Also tryed to change the validation annotation to:
@Validate(on = "view", encrypted = true)
public void setAssignedRoleIds(List<Long> assignedRoleIds) {
this.assignedRoleIds = assignedRoleIds;
}
This results in the following url:
/app/administration/ConsultantRoles.htm?consultantId=QecNk2hZxBY%3D&assignedRoleIds%5B0%5D=1
and the same exception. To be complete here's the logMessage:
[ WARN] 10:12:47

Any hints how to bind a list of Longs?
