While waiting for a fix to overcome the install problems discussed here, I decided to set up a new Mendix instance and create a new database from scratch, bypassing the issues of trying to upgrade an existing instance. The database was created successfully without the issues described in the other posting for an existing database ;-). But the runtime instance will not start. I have the StartDeeplink microflow defined as the after startup microflow, which also calls the LDAP and License Pool microflows. These are currently being skipped with a 1=2 workflow split. The error on startup is: Module: An error occurred while initializing modules java.lang.NumberFormatException: For input string: "false" at java.lang.NumberFormatException.forInputString(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at cK.parseValueFromString(SourceFile:260) at com.mendix.core.conf.Configuration.getConstantValue(SourceFile:785) at lc.<init>(SourceFile:15) at m.n(SourceFile:1117) at m.k(SourceFile:935) at m.j(SourceFile:764) at m.i(SourceFile:663) at m.h(SourceFile:581) at m.g(SourceFile:506) at m.f(SourceFile:431) at m.e(SourceFile:358) at m.d(SourceFile:286) at m.b(SourceFile:189) at m.a(SourceFile:122) at fN.a(SourceFile:34) at cX.a(SourceFile:140) at cX.a(SourceFile:117) at v.a(SourceFile:263) at v.a(SourceFile:139) at go.<init>(SourceFile:52) at com.mendix.core.MxRuntime.H(SourceFile:585) at com.mendix.core.MxRuntime.A(SourceFile:272) at com.mendix.core.MxRuntime.z(SourceFile:252) at com.mendix.core.MxRuntime.a(SourceFile:234) at lz.execute(SourceFile:54) at com.mendix.m2ee.server.handler.AdminHandler.handle(AdminHandler.java:84) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:113) at org.eclipse.jetty.server.Server.handle(Server.java:334) at org.eclipse.jetty.server.HttpConnection.handleRequest(HttpConnection.java:559) at org.eclipse.jetty.server.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:992) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:550) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:203) at org.eclipse.jetty.server.HttpConnection.handle(HttpConnection.java:406) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:462) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:436) at java.lang.Thread.run(Unknown Source) M2EE: An error occurred while executing action 'null'. com.mendix.m2ee.api.AdminException: Starting MxRuntime failed. at com.mendix.core.MxRuntime.z(SourceFile:257) Caused by: com.mendix.m2ee.api.AdminException: An exception occurred while running the after-startup-action at com.mendix.core.MxRuntime.A(SourceFile:292) Caused by: com.mendix.core.CoreException: Exception occurred in action 'EventExtendedAction :: - action: [StartupAction] - before: [DeepLink.StartDeeplink] - replace: null - after: [] ', all database changes executed by this action were rolled back at com.mendix.core.actionmanagement.CoreAction.d(SourceFile:553) Caused by: java.lang.NullPointerException at com.mendix.core.Core.getInputParameters(SourceFile:111) at dd.a(SourceFile:279) at eo.f(SourceFile:71) at eo.a(SourceFile:35) at dd.execute(SourceFile:106) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:473) at it.b(SourceFile:159) at com.mendix.core.MxRuntime.A(SourceFile:290) at com.mendix.core.MxRuntime.z(SourceFile:252) at com.mendix.core.MxRuntime.a(SourceFile:234) at lz.execute(SourceFile:54) at com.mendix.m2ee.server.handler.AdminHandler.handle(AdminHandler.java:84) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:113) at org.eclipse.jetty.server.Server.handle(Server.java:334) at org.eclipse.jetty.server.HttpConnection.handleRequest(HttpConnection.java:559) at org.eclipse.jetty.server.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:992) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:550) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:203) at org.eclipse.jetty.server.HttpConnection.handle(HttpConnection.java:406) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:462) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:436) at java.lang.Thread.run(Unknown Source) As you will see from the image, I have set the runtime constants to false (I haven't yet been able to set up any pools yet), but the runtime seems to be seeing this as a string rather than a boolean.
