[rules-users] [Drools Flow] checking Properties of supplied variables in constraints

[Gregor Ryba]

Hi,

i am supplying an object as variable to my workflow. in a split i try to check 
the property "Type" of the
supplied object and according to it move on to the next actionnode (for testing 
purposes).
in the actionnode i am setting a string, that i am printing out later.

my test looks as follows:

first i supply a ticket with type "reviewer"
after this i supply a ticket with type "developer"

BUT i'm getting the following output:

Output1: processing developer ticket <reviewer>
Output2: processing developer ticket <developer>

so the ticket-object is injected correctly into the workflow, but
i have no clue, why the developer constraint is taken both times

any hints?
