I've a clean install of Aptana as an Eclipse plug-in (fresh installation).
My suspicion that this could be a duplicate key-binding (quite possibly a bug), but information online is sparse.
- Eclipse: 3.5.2-8ubuntu3
- Aptana: 3.0.5.201110061700-7
- Ubuntu: 11.04, kernel 2.6.38-11-generic
Session data:
- eclipse.buildId=M20100211-1343
- java.version=1.6.0_22
- java.vendor=Sun Microsystems Inc.
- BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_NZ
- Command-line arguments: -os linux -ws gtk -arch x86_64
For Python scripts this generally seems OK (for now). I'm starting on a new Ruby script, define an object followed by a "." & try to invoke Content Assist via the ctrl+space keystroke & presented with the following pop-up error:
"Content Assist" did not complete normally. Please see the log for more information.
and
model is already installed
this the stack trace provided:
java.lang.IllegalStateException: model is already installed
