<HTML><HEAD></HEAD><BODY><SPAN>Sirs:</SPAN><BR /><BR /><SPAN>I have been using Eclipse Designer 5.8 in Eclipse Helios Service Release 2 Build id: 20110218-0911 for several months.&nbsp; Now, when I try to edit one of the .activiti files, I get the exception shown below.&nbsp; After trying various things:&nbsp; restarting Eclipse, rebooting the PC (Windows 7), I decided to try to reinstall the Activiti Plugin.&nbsp; The Update Sites provides only version 5.9.&nbsp; I would like to continue using 5.8 untill I reach a clean breaking point in my project (at present I have been tasked to create some load tests for the workflow engine in version 5.8 to use a a benchmark for load testing 5.9).&nbsp; I have worked a little with the 5.9 Designer and it has some huge advantages over the 5.8 designer, but for this project I need to work with the 5.8 Designer.&nbsp; One of the bpmn20 files whose related .activiti file I cannot update is below.&nbsp; </SPAN><BR /><BR /><SPAN>Is there a way for me to download the 5.8 Designer?&nbsp; </SPAN><BR /><BR /><SPAN>Do you have any other suggestions for how I can continue to update my 5.8 processes (the .activiti files)?</SPAN><BR /><BR /><SPAN>Thank you for your help.</SPAN><BR /><BR /><BR /><BR /><SPAN>Exception:</SPAN><BR /><BR /><UL>java.lang.NullPointerException<BR />&nbsp;&nbsp;&nbsp;at
