4:39 a.m.
We have a process which runs some rules against items in the working memory. We then want
to use one of the objects in the working memory as the input parameter to a work item.
The only way I can see to do this is to use a script step to fetch the fact from the wm
(via a query or whatever) and then set a global, then have the global map into the in
paramater. This however seems very messy, scoping the variable far larger than it needs
to.
Is there a more appropriate solution which doesn't pollute the global variable
namespace - perhaps running some code in the work items on entry action to populate the
parameter directly?
Thanks,
Thomas

what about adding the same object that you are inserting in the working
memory as a process parameter?
Are you generating new objects inside your rules and then you want to inject
that inside a work item?
Work Items have their own scope that should be decoupled from the knowledge
session, so you need to find a way to copy the information from the working
memory scope to the work item scope and the first thing that comes into my
mind is to do it in the easiest way that it's to include that information in
the process scope.
Greetings.

They are new objects - or at least we don't know which version of the object it is
until the rules have run and worked it out.

what do you mean with version of the object?
We usually solve that with the on-entry actions of the nodes, but the BPMN2
spec don't define those hooks to be able to execute code before and after
each node.
Let me review the code to see how it can be done right now.
If you include a script task before the workitem you can get the fact from
the working memory and set a process variable before calling the work item.
Greetings.

5:30 a.m.
The rules load objects from the database, and also create new ones. One of the instances
is the one we want to work on later - this we can get with a query.
The script task is the way we are looking at the moment, it would be nice if we could skip
that out and just directly map the parameter to be the value returned by query directly.
Thanks for the help,
Thomas

yes
I totally agree with that..
We usually use expressions to resolve that kind of things.
