Using Expressions for Role Assignments

Using Expressions for Role Assignments

Select the value of the Role assignment: literal, expression, or Logical People Group.
Use the Expression option to write a conditional expression for selecting task or notification-related roles. The expression can be based on the input data of a People activity. For example, if you are invoking a service to retrieve identities, you can pass them into the potential owners or administrators identities.
The expression can include a process variable or it can be composed using WS-HT custom XPath functions, described in
Custom Functions
.
To Add an Expression for a Task or Notification Role:
  1. From the Outline View, select task or notification.
  2. In the Assignment tab of the Properties view, select a role, such as
    potential owners
    .
  3. In the Value column, click (
    ...
    ).
  4. Select Expression as the Source, and then select
    Expression Builder
    .
  5. In the Expression Builder, select a Human Task (WS-HT) custom function or other variable in creating an expression.
  6. Select the users or groups for the role.
XML Syntax
<htd:from expressionLanguage="anyURI"?>     expression </htd:from>
Example: Expression for a Task’s Role Assignment
<htd:potentialOwners>    <htd:from>$voters/users/user[i]</htd:from> </htd:potentialOwners>
The potential owners definition is contained within a For Each activity.
Example: Using a WS-HT Custom Function
:
<htd:potentialOwners>     <htd:from>         htd:getInput("part1")/approvers     </htd:from> </htd:potentialOwners> <htd:businessAdministrators>     <htd:from>         htd:except(htd:getInput("part1")/admins,         htd:getInput("part1")/globaladmins[0])     </htd:from> </htd:businessAdministrators>
The WS-HT custom function
getInput
returns a list of potential owners defined as the child element
approvers
in
part1
of the task's input message. The business administrators group includes
globaladmins
and excludes
admins
.
Example: A Notification's Role Assignment
<htd:peopleAssignments>   <htd:recipients>    <htd:from>      htd:getPotentialOwners("ApproveClaim")    </htd:from>   </htd:recipients> </htd:peopleAssignments>
Example: XQuery
<htd:potentialOwners>  <htd:from>   <htd:literal>    <ht:organizationalEntity      xmlns:ht='http://www.example.org/WS-HT'>     <ht:groups>      <ht:group>{data($creditInformation/loan:loanTypeGroup)}      </ht:group>     </ht:groups>    </ht:organizationalEntity>      </ht:literal>    </ht:from> </ht:potentialOwners>
