href="http://www.activiti.org/userguide/#eclipseDesignerInstallation" rel="nofollow noopener noreferrer">http://www.activiti.org/userguide/#eclipseDesignerInstallation</A><SPAN> and, after starting eclipse as Administrator, I opened a new Activiti Project. </SPAN><BR /><SPAN>After that, in the root directory of the project I added a "diagrams" folder and, inside it, I made a new file saved as "first-diagram.bpmn".</SPAN><BR /><BR /><SPAN>Now, as I try to put anything in the diagram (as StartEvent, UserTask, etc) I receive errors from eclipse. </SPAN><BR /><BR /><SPAN>Here one of
