1.0 M8 [message #140714]

Originally posted by: user.domain.invalid

In the past, I have been able to simply able to unzip new milestones and
have all my projects working. Now going from 0.7 to 1.0M8, I get an
error opening up html or xml with the following error.

Unable to create this part due to an internal error. Reason for the
failure: The editor class could not be instantiated. This usually
indicates that the editor's class name was mistyped in plugin.xml.

Eclipse remembers the last editor you used for a particular file
based on its ID. The IDs and classes changed in 1.0M8. While
simply unzipping a newer build over an older one is rarely a good
idea, you might be able to work around this by using the Open With
context menu in the navigator view you're using.
