Better error message what is wrong in a custom wizard for addon developers -------------------------------------------------------------------------- Key: FORGE-2548 URL: https://issues.jboss.org/browse/FORGE-2548 Project: Forge Issue Type: Enhancement Affects Versions: 3.0.0.Alpha2 Reporter: Claus Ibsen When you develop custom addon's then various things can go wrong. And whether the command runs in CLI or IDEA or Eclipse then it works a little bit differently. I have a command wizard that fails with this cryptic index out of bounds exception. I finally found the stracktrace in idea.log file, as IDEA itself says nothing {code} 2015-12-08 10:45:34,976 [ 148775] ERROR - llij.ide.plugins.PluginManager - Index: 2, Size: 2 java.lang.IndexOutOfBoundsException: Index: 2, Size: 2 at java.util.ArrayList.rangeCheck(ArrayList.java:653) at java.util.ArrayList.get(ArrayList.java:429) at org.jboss.forge.addon.ui.impl.controller.WizardCommandControllerImpl.getCurrentEntry(WizardCommandControllerImpl.java:491) at org.jboss.forge.addon.ui.impl.controller.WizardCommandControllerImpl.getCurrentController(WizardCommandControllerImpl.java:502) at org.jboss.forge.addon.ui.impl.controller.WizardCommandControllerImpl.getInputs(WizardCommandControllerImpl.java:244) at org.jboss.forge.addon.ui.impl.controller.NoUIWizardControllerDecorator.getInputs(NoUIWizardControllerDecorator.java:189) {code} As all the stacktrace is purely in forge code, I cannot really see what I do wrong. Can you guys improve that part of the code that has the index out of bounds and do a better exception message that can help me what is the problem / as well other addon developers.
