<DIV><FONT size=2 face=Arial>This is a known limitation when using BPMN2.
Check out the documentation, that describes which features are implemented
already in the BPMN2 implementation:</FONT></DIV>

<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Priorities are not yet implemented as it seems the
BPMN2 spec simply does not define something like this. If we want to
support something like this, we will probably have to define a custom extension
(but we didn't do this yet as we wanted to wait until the spec was final before
starting to add too much custom extensions).</FONT></DIV>

<DIV><FONT size=2 face=Arial>A workaround would be to use mutually exclusive

latest snapshot -- Gateway (Diverge) : Split Node - Priority Does not
Work</DIV>
<DIV><BR></DIV>
<DIV class=Section1>
<P class=MsoNormal>Hi All,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>In the Drools Flow 5.1 latest snapshot , for the node
(Gateway (Diverge) : Split Node), somehow priority does not work. If we set
some value, lets say 100 and open the process file(BPMN2) again and check the
priority – somehow it doesn’t retains the priority value and reports the value
always as 0.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I am trying to make use one of the feature of XOR type node
where one of the constraint is “always true” with the highest priority. I hope
my understanding is right.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>This is what the Drools Flow Doc says:<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal><SPAN

means that exactly one of the outgoing connections will be chosen. The
decision is made by evaluating the constraints that are linked to each of the
outgoing connections. Constraints are specified using the same syntax as the
left-hand side of a rule. The constraint with the <EM><SPAN
style="FONT-FAMILY: 'Verdana','sans-serif'">lowest</SPAN></EM> priority number
that evaluates to true is selected. Note that you should always make sure that
at least one of the outgoing connections will evaluate to true at runtime (the
ruleflow will throw an exception at runtime if it cannot find at least one
outgoing connection). For example, you could use a connection which is always
true (default) with a <EM><SPAN
style="FONT-FAMILY: 'Verdana','sans-serif'">high</SPAN></EM> priority number
to specify what should happen if none of the other connections can be
taken.</SPAN><o:p></o:p></P>
