[jira] Commented: (TAPESTRY-1281) NullPointerException in page
rendering
[ https://issues.apache.org/jira/browse/TAPESTRY-1281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474809 ]
Boris Terzic commented on TAPESTRY-1281:
----------------------------------------
Apologies, I'm an idiot. Sorry for wasting your time. I had been reading about @ApplicationState and wanted to annotate that property as such knowing that on first access a default instance would be created. Obviously I didn't.
