Hello Everyone, I am new for jBPM. I have installed jbpm-6.0.1.Final-installer-full for learning. I installed the program by running ant install.demo. There is no error messages in the installation. I can access the workbench. But when I choose to new a build process, the process designer view cannot open. There is only a blank area in the browser. Who can help me? Thanks! anguang 2014-06-26 anguang1973
