Hi all,I'm trying to define some new roles in Alfresco, so I headed to permissionDefinitions.xml in model folder and added a new role (since I think this file can't be extended with a permissionDefinitions-custom.xml placed at extension folder) called "Deleter", just this way:<permissionSet type="cm:cmobject" expose="selected">
[…]
<permissionGroup name="Deleter" allowFullControl="false" expose="true" >
<includePermissionGroup permissionGroup="Read" type="sys:base" />
<includePermissionGroup permissionGroup="Delete" type="sys:base" />
</permissionGroup>
</permissionSet>
<permissionSet type="cm:content" expose="selected">
<permissionGroup name="Coordinator" extends="true" expose="true"/>
<permissionGroup name="Collaborator" extends="true" expose="true"/>
<permissionGroup name="Contributor" extends="true" expose="true"/>
<permissionGroup name="Editor" extends="true" expose="true"/>
<permissionGroup name="Consumer" extends="true" expose="true"/>
<permissionGroup name="Deleter" extends="true" expose="true">
</permissionSet>
After re-starting the server, I've tried to invite a user to other user's space and give him the "Deleter" role…In the "Invite Users Wizard" I see the role name between this characters '$$'; that is to say, I see: $$Deleter$$And I can't assign this role to any user (click on 'Add to list' leads to no action) :? What I've done wrong?? How can I add new roles to Alfresco's model??What does "exposed" supposed to mean?I've another question that might be some kind of stupid, but I would like to get it right… Roles are just sets of permissions that cannot be used as authorities, right?If I want to grant access to a folder to all users that are defined as 'Contributors', I should create a group containing all those users who have this role and grant access to that group, shouldn't I?Any help would be very much appreciated.Thanks in advance,EnriquePD: sorry for my bad English
