When selecting an user picker _All or an user picker _Any , you are able (Optionally) to specify expressions that identify

just clicking on the icon showing on the right side of the select list:

The Auto populate user picker field based on expression dialog requires an expression specifying the users to insert in the user picker field and optionally  the users to erase from the list.

 You cannot specify the users to exclude (Excluded) without specify the users to add to the list (Can Approve or Reject).

 You are able to insert the allowed tags on the text areas simply performing a drag and drop of a tag inside the text area on the point you want add it.

Expected syntax 

A valid expression requires that you respect the expected syntax.

The following diagram illustrates the expected syntax for valid expressions that you can specify in the Can Approve or Reject and the Excluded text areas:

The syntax that allows to specify the property's values expects a start end tag identifying the property:

• <users>...</users>
• <groups>....</groups>
• <roles>....</roles>
• <group-pickers>...</group-pickers>
• <user-pickers>...</user-pickers>
• <component-leads>..</component-leads>.

You are able to specify one or more Property's values.

Property's values are concatenated via the '&'.

 Example: <users>Tom Black & Nancy Green & Jack Red & Katy White</users>

The syntax that allows to specify a condition enabling a set of properties expect the following start end tag: 

• <conditional-rule  name="Conditional Rule Name">...</conditional-rule>

An expression can include zero, ore, more conditions enabling one or more properties.

Example Example: <conditional-rule  name="Priority High"><groups>Managers</groups> </conditional-rule> <conditional-rule  name="Priority Low"><users>Tom Black</users></conditional-rule>
