[rules-users] Re: Inserting Facts within "Action nodes" (RuleFlow)

[Massi Gmail]

Thank you very much Kris.

I will define such a rule.

thanks again.

Now I am experiencing something different...

I would like to introduce if\while statements into the action node
 "code part".

Is that possible?

Every time i introduce such a statement into
the "textual editor "I get back a Mvel exception.

In case It were not possible, I think I would use
another rule like the one you suggested me.

Grazie.

Massi

  The ruleflow action node can be used to specify some action (as a piece of code) that should be executed.  Currently, it only has access to global variables.  It might indeed be a good idea to also allow access to some kind of workingMemory variable.  We will try to add support for that when we add support for process variables.  If you want, you could open a JIRA for this to track the issue.

  Your solution, defining wm as a global, seems a possible workaround (and I don't see any problems that might arise by doing this).  Another one would be using a ruleset node instead of an actionNode, and specifying a rule that does not have any conditions, something like:

  rule "MyRule"
    ruleflow-group "MyAction"
    when
    then
      insert(new Object());
  end

    Hi guys,

    Is it possible to insert a new fact in the ruleflow action nodes?

    I tried it simply adding an "insert(new Object())" instruction
    in the action-node "textual editor" but I got back the following
    exception:

    org.mvel.PropertyAccessException

    : unable to resolve property: insert(new Object()) 
    Is it a simple dialect issue ? How to do it correctly?

    Thank You!



    Massi
