The Approval Configuration screen allows you to specify expressions that will be used to populate an user picker_All and the user picker _Any that have been selected for an Approval Configuration.

Auto populate user picker field based on expression screen

The Approval Configuration screen displays the available properties to setup an Approval :

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

users that will be filled on the user picker custom field in order to enable them to approve and
users that will be removed by the user picker in order to exclude them.

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

Insert expressions identifying the users to insert in the user picker custom field

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.

Example

Test the expression

You are able to test an expression in order to check if the list of users returned for an issue, on evaluating the Can Approve or Reject and Excluded, matches the expectations.

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