<div class=Section1>
<p class=MsoNormal>I am seeing a problem in the latest stable build 12/27 andn
1/26 where a flow variable does not get updates from a facts updated in a rule
node in the flow. Both the flow variable and the fact are initially the
same object instance, but It looks like the flow variable gets a cloned
instance after the rule node. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am inserting 1 fact and running a flow with a debug node,
a rule node, a debug node, and a human task. As you can see below the
hashcode changes for the flow variable after the rule node, but retains the
user value set earlier in the flow. After the rule node the user should
be myuser which is set in the rule, but instead has the value bogus, which is
set in the first debug node. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is anyone else seeing similar issues in drools flow?
This is happening when we run in JBoss 5.1. This is a blocking
issue that makes drools flow unusable for us, so any help you can provide is
appreciated. <o:p></o:p></p>
