In our production environment we see a large number of errors related to
the CError channel. (Around 6000 a day). We are running uPortal 3.1
trunk patched up to r44717.
The errors come from the
'org.jasig.portal.layout.node.UserLayoutChannelDescription' package
starting with this message:
Unable to load class for name 'org.jasig.portal.channels.CError' for channel
with pubId='null', fname='null'.
java.lang.ClassNotFoundException: org.jasig.portal.channels.CError
I searched the uPortal source for 'org.jasig.portal.channels.CError' and
found that the class has moved to
org.jasig.portal.channels.error.CError. I found one hard coded
reference to the old path in ChannelDefiniton.java. I've created a JIRA
item about this:
http://www.ja-sig.org/issues/browse/UP-2289
However, this getDocument method is not in the stacktrace for the
error. I'm confused where the old CError reference is coming from.
There is no CError channel in UP_CHANNEL. (There is no CError channel
in entities)
I'll paste the full error bellow.
