<div class="jive-rendered-content"><p>Hi all,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I have a node with three outgoing conditional transitions.  The idea is that by firing one event, jBPM will transition to the appropriate state based on the conditions applied to the transitions.       </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>However this is not happening.  jBPM picks up the first transition with the given name, checks the condition on it, and if condition evaluates to false it throws an exception (<em>Exception in thread "main" org.jbpm.JbpmException: transition condition #{ ... } evaluated to 'false'</em>) and aborts the transition. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For example,  </p><p>I have the following states,</p><ul><ul><li>state A transitions to state B on event X if (var == foo)</li><li>state A transitions to state C on event X if (var == bar)</li><li>state A transitions to state D on event X if (var == foobar)</li></ul></ul><p>If I fire event X (and var = foobar), jBPM will only pick up the transition going to state B and fail because var != foo</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Why is this so and is there a way around it?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Ed</p></div>
