[jbosstools-issues] [JBoss JIRA] (JBIDE-10527) NullPointerException when creating OpenShift server manually

[Rob Stryker (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-10527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12688291#comment-12688291 ] 

Rob Stryker commented on JBIDE-10527:
-------------------------------------

This has been a hell of an issue over hte past several months ;)  It seems wizard fragments are only instantiated once, and are expected to be cleaned out of state. It also seems that they are asked if they're complete, potentially before they've even been created. 

Anyway, I committed a new patch that cleans up on finish and cancel and ensures the error strings (which determine whether 'finish' is enabled or not) are correct. 

Damn... what a ride.
