Expressions

It is possible to configure expressions for some of the configuration items:

  • Business object field's default values
  • Business object calculated field's
  • Constraint conditions,
  • Etc.

All expressions are using the Rhino server-side scripting language.

For ease of use, within the expressions you can also use preprocessed tags (enclosed in brackets []). These tags are substituted with their script equivalence before the scripted expression is actually evaluated.

Summary​

Here is a summary of available preprocessed tags that can be used in expressions.

Note: The comprehensive descriptions below (and the JavaDoc) contains additional information.

Description​

Configuration items' expressions (e.g. calculated fields, constraints, state transition expressions, etc.) are in fact fragments of Rhino script code.

They are similar to the main script you can implement to extend the configuration item behavior. The main difference is on the bindings namings, for instance for a business object the this you use in the main script is available as obj in the expressions.

In addition there are some preprocessed tags that are substituted to their corresponding script code at runtime. For instance [VALUE:myField] is in fact substituted as obj.getFieldValue("myField"). Using substituted tags is therefore not mandatory, consider them as "shorthands" to have easy to read expressions.

Here is the list of available substituted tags that you can use in expressions:

UI URLs tags​

Available tags:​

  • [HOMEURL] : Home URL (without quotes) _ [EXTOBJECTURL:<external object name>[:<optional URL parameters>]] : External object URL (without quotes)

Grant level​

Available bindings:​

  • grant: the grant object

Available tags:​

  • [GRANT]: the user grant
  • [LOGIN]: the user login
  • [USERID]: the user row ID
  • [LANG]: the user language
  • [HASRESP:<group>] or [HASRESPONSIBILITY:<group>]: check if user has specified responsibility
  • [TEXT:<code>]: value of a static text
  • [SYSPARAM:<name>]: value of a system parameter (without surrounding quotes because a system parameter can be numeric)
  • [APPLICATION] or [APPNAME]: the application name
  • [ENCODING]: the application encoding
  • [NOW] (deprecated) or [DATE[:day offset]]: current date in service format yyyy-MM-dd (with optional day offset)

  • [WEEK]: current week in format WW
  • [LOV:<list name>:<code>] or [LISTVALUE:<list name>:<code>]: value of a list of values code
  • [TEXT:<code>]: static text in user language
  • [OBJECT:<object name>[:<optional object instance name>]]: the specified object (by default it uses temporary instance)

Note: the UI URLs tags are also avilable at grant-level

Business object level​

Available bindings:​

  • obj: the object
  • row: the current row (for lists)
  • parent: the parent object (if relevant)
  • parentRefField: the parent object reference field (if relevant)
  • context: the context

Note: The grant level bindings are also available at business object level.

Available tags:​

  • [OLDVALUE:<field input name>]: the specified input field old value (not available on lists)
  • [PARAM:<parameter name>]: object parameter value

Note: The UI URLs and grant level tags are also available at business object level.

External object level​

Available bindings:​

  • obj: the external object

Note: The grant level bindings are also available at business object level.

Available tags:​

  • [OBJECT]: the current external object
  • [OBJECTID]: the current external object's row ID

Advanced​

It is possible to write complex expressions by using self calling functions such as:

(function() {
    var res = "";
    // Do some complex stuff with res
    return res;
})();
