problem with editor

[rmiarka]

Hello

I just installed Eclipse and the Haskell plug-in.

Unfortunately, I get an error when I try to open a new Haskell module (Test.hs): "Editor could not be initialized."

Does anyone have any hints?

(I have both Hugs and GHC installed and my empty Test.hs runs in with both.)

Thanks,
Ralph

Rich,

this could be an incompatibility. The plugin version 0.8 requires the last Eclipse 3.1 Milestone (M7). That's at least against what I compiled. From the timestamp in your log it looks like you're using an older Eclipse.

Ciao,
Leif

[Rich]

Thanks, I will give that a try.  I was using the latest release version of Eclipse, 3.0.2.

[Rich]

Yes, it was the Eclipse version.  I tried 3.1M7 and everything seems to work OK now.
