Server error: An unknown exception occurred caused by: 3 ??!
0
Hi, I'm getting this exception in a couple of java actions but not really sure what the statement cased by: 3 means. It's when trying to instantiate the actions. If I remove the call to a particular java action and microflow only runs the second java call, I get the same type of exception, stating: error caused by: 4 instead of 3. Does anyone knows what exactly this means? Super class issue? classpath?! version of Mendix (2433). 2013-04-22 11:13:15.092 ERROR - MICROFLOWENGINE: Exception occurred in microflow 'PipsAndSubbies.job_readFile' for activity 'Clear the input table'', all database changes executed by this microflow were rolled back 2013-04-22 11:13:15.092 ERROR -
