<HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I have downloaded the 1.4 preview to test the jBPM functionalities.</SPAN><BR /><BR /><SPAN>Installation went smoothly, but when I try to start a workflow I got an error in the Web client.</SPAN><BR /><BR /><SPAN>"Please correct the errors below then click Finish. </SPAN><BR /><SPAN>A system error happened during the operation: Failed to signal transition 'null' from workflow task 'jbpm$1' "</SPAN><BR /><BR /><SPAN>I have included a copy of my console from the startup as there are already jBPM message during deployment.</SPAN><BR /><BR /><SPAN>Can you point me to the problem.</SPAN><BR /><BR /><SPAN>Regards</SPAN><BR /><BR /><SPAN>BMI</SPAN><BR /><BR /><SPAN>I'm using the Tomcat version with java SET JAVA_HOME=D:\jdk1.5.0_08</SPAN><BR /><SPAN>and mysql database</SPAN><BR /><BR /><BR /><SPAN>18:31:23,526 WARN&nbsp; [org.hibernate.cache.EhCacheProvider] Could not find configuration
