[forge-issues] [JBoss JIRA] (FORGE-2548) Better error message what is wrong in a custom wizard for addon developers

[Claus Ibsen (JIRA)]

    [ https://issues.jboss.org/browse/FORGE-2548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13138420#comment-13138420 ] 

Claus Ibsen commented on FORGE-2548:
------------------------------------

Some of the other camel components work fine, usually with fewer options such as ahc (the first one).

But the ones with many options like jms, file, netty4-http fails. I suspect its related maybe to a dodgy UIInput that somehow causes something internally in IDEA to fail etc. There was once a problem with UISelectOne type (from enum) that the value choice and the default value was not 100% identical. eg different in lower vs upper case in a String etc. Also maybe a UISelectOne must it have a defaultValue set?

> 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

> 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.
