Martin Cassidy created WICKET-6126:
--------------------------------------
Summary: ThreadContext in WicketFilter init()
Key: WICKET-6126
URL: https://issues.apache.org/jira/browse/WICKET-6126
Project: Wicket
Issue Type: Bug
Components: wicket
Reporter: Martin Cassidy
Priority: Minor
I'm combing Wicket, wicket stuff portlets and Apache Pluto to create
portal/portlet application.
Some portlets exist within the same context and the portal application, which
means the I have 2 wicket filters and 2 wicket applications running in the same
context.
The standard wicket filter serves the portal requests and matches /* patterns,
the PortletFilter from wicketstuff matches /PlutoInvoker/*
Each filter uses a different application class (I did try using just one
application and one filter but this didn't work because of what PortletFilter
does the the application it's attached to)
I'm not sure about other servlet containers, but at least on undertow with
Wildfly 10, filters are not initialised until the first time that they called
upon to process a requires.
Whilst the WicketFilter doFilter() method can handle multple invocations per
request by saving and restoring the ThreadContext, the ini() does not do this
which means for the first request to the application the invocation order is:
# WicketFilter.init()
# WicketFilter.doFilter()
# PortletFilter.init()
# PortletFilter.doFilter()
Which causes the following:

The 2nd and any subsequent requests are fine, as the init()s have run and
doFilter() handles the ThreadContext correctly.
