Friendly Enough Expression Language, or FEEL, is a new standard promoted by the OMG. The DCR Process Engine has implemented a subset of the FEEL langage as it’s expression language.
The DCR Process Engine 4.8.0 introduces support for FEEL lists.
An example FEEL list of the numbers 1, 2 and 3 is written in this way:
[1, 2, 3]
In a similar manner a FEEL list of strings can be written as:
list contains(<list>, <value>) –> true | false
count(<list>) –> integer value with the number of elements in the list
append(<list>,<element>) –> returns a new list where the element is appended to the list
concatenate(<list1>,<list2>) –> returns a new list where the two lists are concatenated
