Hi,

The problem is the following line in the Explorer code:

if (group.getType().equals("assignment")) {
I think you don't set a group type when retrieving the groups from LDAP is that right?
The Explorer works with group types to determine to which groups a user task can be assigned.

Best regards,

[sarkar92]

you are right…

thanks a lot…
