Hello, I’m having trouble to run a simulation, that was runed in SPIS4, in SPIS5.0.1
I’ve allready tried the Legacy Proyect Converter and it outputs this error:
* * *
java.lang.NullPointerException at org.spis.ui.model.DefaultSpisModel.(DefaultSpisModel.java:71) at org.spis.ui.model.DefaultSpisModel.(DefaultSpisModel.java) at org.spis.ui.project.converter.command.ConvertCommand.run(ConvertComma nd.java:70) at org.spis.ui.project.converter.command.ConvertCommand.run(ConvertComma nd.java:50) at org.keridwen.core.messaging.AbstractCommand.execute(AbstractCommand.j ava:173) at org.keridwen.core.messaging.DefaultBundleController$CallableCommand.c all(DefaultBundleController.java:229) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source ) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

Also I've tried to run the simulation copying exactly the same global parameters but when I do that another error pops up after the global parameters screen. Have some global parameters changed in SPIS5 with respect to SPIS4? Thanks, Federico Di Vruno
