[rules-users] Can an Object inside a map be used in guvnor

[Michael Anstis]

Hello,

Using Guvnors "guided" features you cannot create constructs like this:
HashMap(this["amount"]!=null)

The only solution is to use a free-format DRL fragment (in either the
Guided Rule Editor, Guided Template Editor or Guided Decision Table).

With Guided Templates and Guided Decision Tables you could make the map key
a "template key" so values can be defined elsewhere:
HashMap(this["@{key}"]!=null)

An alternative to a free-format DRL fragment would be to define a DSL. DSLs
can be used in any of the foregoing editors.

With kind regards,

Mike
