I suspect the answer to my question is going to be one of those "smack forehead" moments when someone points out the obvious.....but here goes....
I have happily had Eclipse LUNA runing with the CSIDE plugin. Recently, I went to ugprade the plugin to v 10.5.5 and assumed that all I needed to do was remove the existing com.opentext.cside_10.5.0.285.jar file from my Eclipse Plugins directory and drop in the newer one (com.opentext.cside_10.5.5.327).
However, once I did this, I can no longer see or use the OScript perspective or features.
I've tried same approach with prior CSIDE plugin versions to check it's not an issue with 10.5.5, but all exhibit same issue.
So - to upgrade CSIDE, do we need to remove the prior plugin JARs or do we simply continue do add these to our Eclipse plugin directory?
