MyFaces action handling sometimes fails with exception from ExternalContext
setRequestCharacterSetEncoding
----------------------------------------------------------------------------------------------------------
Key: PORTLETBRIDGE-43
URL: https://issues.apache.org/jira/browse/PORTLETBRIDGE-43
Project: MyFaces Portlet Bridge
Issue Type: Bug
Components: Impl
Affects Versions: 1.0.0, 2.0.0
Reporter: Michael Freedman
Assignee: Michael Freedman
In some configurations (noteably when Facelets is used), an exception is thrown
when MyFaces tries to set the request character encoding during an action. The
exception claims that the request (parameters) have already been read and hence
one can't do this set. This occurs because the Bridge reads the request
parameters during ExternalContext construction to determine the view target of
the request (if encodes this target in a render parameter). Fix is to delay
determining the view until Faces actually tries to determine it itself. I.e.
Don't resolve the view until either EC.getRequestPathInfo or
EC.getRequestServletPath are called. Note: because at least older version of
the Faces RI we support don't call these (in the portlet case) but rather
relies on a request attribute being set -- the bridge must also detect/resolve
the view for this case as well.
