I did this, some time ago to access a variable from a split node constraint (not sure if it still works):<br><br>$processInstance : ProcessInstanceImpl( )<br>VariableScopeInstance(variables["customerLoanRating"] >= 1000) from $processInstance.getContextInstance(VariableScope.VARIABLE_SCOPE)<br>
<br>You need to insert the process instance into the session.<br><br>You may want to look at various examples in examples.zip downloadable from <a href="http://www.jboss.org/drools/downloads.html">http://www.jboss.org/drools/downloads.html</a><br>

Hi,<br><br>I'm not a new drools user but I started to test rule flows (5.0M5) recently and I'm stucked, so any clue will be welcomed :). I'm testing how to share a StatefulKnowledgeSession between N rule flow instances. I'm trying to parametrize each instance with process variables at start time but I don't know how to use them from rule constraints (in event waits, splits, etc.). I've read the documentation and I've found this text related to constraints "<a>Both rule and code constraints have access to globals that are defined for
the process and can reuse imports at the process level." I tried it assigning </a><a>(from an action)</a><a> a variable value to a global variable but it's not working for me. ŋI'm missing something?<br>
<br>Thanks in advance!<br><br>Ricardo.<br></a>
