[ https://issues.apache.org/jira/browse/WICKET-6842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Johannes Renoth updated WICKET-6842:
------------------------------------
Description:
I am not 100% sure if this is a bug in Wicket but i have the following stacktrace from our application:
{code:java}

I have a Form component inside a Border inside a Form (if that is relevant)
I dont think onbeforeRender should be called in the render phase of another component (which ultimately leads to this error).
