 Role is duplicated by ''RoleDuplicateBulkAction'' bulk action. This action propagate ''DUPLICATE'' event type with content: Role is duplicated by ''RoleDuplicateBulkAction'' bulk action. This action propagate ''DUPLICATE'' event type with content:

 Creating duplicate role is then propagated into registered (and enabled) entity event processors. Custom processors can be registered by the different module (or product processor can be disabled and overriden, see below). Creating duplicate role is then propagated into registered (and enabled) entity event processors. Custom processors can be registered by the different module (or product processor can be disabled and overriden, see below).

 +Processors can register form attributes into the bulk action form - distinct form attributes (by code, the first attribute wins by processor's order) are rendered and used as input for the bulk action.
 +
 +<note tip>Form attributes registered by processor can be localized in the custom module. Each attribute can have different module - module is preset automatically by the processor's module.</note>
 +
 +<note tip>If role is duplicated into different environment and role with the same base code already exists there, then new role on the target environment is not created, but updated by the source (selected) role. E.g. when some basic role attribute is changed or some automatic role is added => this changes can be "synchronized" into target role repetitively. **Roles are paired between environments by the base code** => if base code is changed, then new duplicate will be created.</note>

 +Duplicate configured role composition (sub roles by business role definition) and duplicate sub roles recursively. If the same environment is selected, the only role composition is created - existing sub roles are used. If the different environment (~target environment) is used, then sub roles with the same environment as original are duplicated recursively into target environment.

 +Parameters provided to the bulk action form:
 +  * **Duplicate sub roles (by business role definition)** - if business role configuration will be duplicated (recursively).
 +
 +Overidable methods (can be used for on the projects, e.g. example below):
 +  * ''duplicateRecursively'' - Returns true, when role should be cloned recursively - can be overriden, if some role hasn't be cloned recursively, if doesn't exist on the target environment before.
 +  * ''includeComposition'' - Returns true, when role composition should be included in the target role - can be overriden, if some role hasn't be cloned recursively, if doesn't have the same environment etc.

 +===== Entity state usage =====
  
-- DUPLICATE event + event content (original, duplicate = content), registered processors, orders (+ link from events), recursion, duplicate on the same vs. different environment. +When some role composition or automatic role (~related entity) is removed from the source role and role is duplicated into different environment repetitively (=> update), then all removed related entities are removed at the end of the bulk action to prevent some account on target system (''acc'') will be removed and created again. When bulk action is processed (by processors) and some related entity has to be removed, then entity state ''deleted'' is created for this entity only. All entities with the ''deleted'' state are removed at end. States are marked with ''transactionId'', which creates envelope for all states creates by one bulk action => only states for the current bulk action are processed.
-- registered processors tells the bulk action code. +
-- entity state deleted - usage +
-- create duplicate vs update duplicate +
-- how to register new processor (example) +
-- how to override processor + custom from test+
