[rules-users] More JBoss Rules IDE 4.x upgrade Woes

All I have to that upgrading a 3.0.x JBoss rules project to a 4.0.x version is not the smoothest transition. First, I reported that the library path is not correct but I was able to work around this issue. Now, I found another feature/bug. When I click on RETE view, I get the following exception: !ENTRY org.drools.eclipse 4 120 2007-07-08 17:54:09.181 !MESSAGE Internal error in Drools Plugin: !STACK 0 java.lang.Exception: Unable to parse rules to show RETE view! at org.drools.eclipse.editors.rete.ReteViewer.loadReteModel(Unknown Source) at org.drools.eclipse.editors.DRLRuleEditor2$3.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run( ModalContext.java:113) !ENTRY org.drools.eclipse 4 120 2007-07-08 17:54: 09.259 !MESSAGE Internal error in Drools Plugin: !STACK 0 java.lang.reflect.InvocationTargetException at org.drools.eclipse.editors.DRLRuleEditor2$3.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run( ModalContext.java:113) Caused by: java.lang.Exception: Unable to parse rules to show RETE view! at org.drools.eclipse.editors.rete.ReteViewer.loadReteModel(Unknown Source) ... 2 more Root exception: java.lang.Exception: Unable to parse rules to show RETE view! at org.drools.eclipse.editors.rete.ReteViewer.loadReteModel(Unknown Source) at org.drools.eclipse.editors.DRLRuleEditor2$3.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run( ModalContext.java:113) Do I really have to create a new Project and re-import everything over to it to get it to work properly? Is there no upgrade feature that automatically upgrades my project like in most other Eclipse plugins? Thanks! Ron
