DMN14 — New built-in function to merge/concatenate two or more contexts

  • Key: DMN14-182
  • Status: closed  
  • Source: Camunda Services GmbH ( Mr. Philipp Ossler)
  • Summary:

    Currently, it is not possible to merge/concatenate two or more contexts. A context can only be declared statically.

    We need to model a decision that gets two or more contexts and returns a new context that includes all entries of the given contexts.


    • introduce a new built-in function similar to the concatenate() function of lists but for contexts
    • it is named `put all` (like Java's Map#putAll function)
    • it has one argument: contexts... (type: list<context<Any>>)
    • it returns a new context that includes all entries from the given contexts
    • it might override context entries if the keys are equal. The entries are overridden in the same order as the contexts are passed in the function
    put all({x:1}, {y:2})
    // returns: {x:1, y:2}
