Scala worksheet works intermittently

[thuff]

I know this was a problem with previous versions of ScalaIDE but I still appear to have the isue. When I create a worksheet, with the initial

object session {
  println("Welcome to the Scala worksheet")
}
I get the output in hte right panel. But when I ad 1+1, I don't get any results. When I try removing my entry, and save,  I still don't get any results in the right panel. What I see in the scala.log is:

Notice I tried the current RC2 release to see if the problem was addressed but it's the same as 4.4.0. I'm trying to complete a project and could really use this feature. Has anyone ran across this? Do I ned to install another version of the worksheets?

UPDATE: forgot to include the ScalaIDE is Luna eclipse and my OS in Ubuntu 16.04 LTS in Virtual Box VM. 

No  one has experienced this problem? Do I need to provide more information?

Hello,

I tested it several times in way described by you but everything looks ok. Honestly I don't understand how your Scala IDE is Luna if it should be Neon (eclipse version 4.6.0-xxx is actually Neon)

OK I confused. On scala-ide.org the latest GA release is 4.4.1, 4.5.0 is the current release candidate #2. How are you on 4.6.0 neon? Am I downloading from the wrong site?

[thuff]

Ok wpopie I think it was a finger check with 4.6.0 cause 4.5.0 is neon.1. The question I have is what worksheet version  do you have as well as the scala version, 2.10 or 2.11?

[wpopie...@virtuslab.com]

default one, so 2.11.8. Worksheet version 0.6.0.

UPDATE: wpopie you are correct. It's version 4.6.1 eclipse , neon with the versions of scala  worksheets  you mentioned. I downloaded JDK 1.8.111 (64) and Scala_IDE 4.5 (neon) to windows. Installed and everything works as expected. The difference I noticed, in Windows when I save the worksheet, there's no asterisk next to the worksheets name after the save. In other words, the file is actually saved. In Ubuntu, there is always an asterisk beside the worksheets name. It seems like the file's never save. I checked the permissions and I own the workspace and subsequent files and folders,  the folders are 775, the worksheet is 664. I changed the folders to 777 and the worksheet to 666, with still the same problem.

Glad to hear that it's working, I try to give a look on Ubuntu installation. Cannot promise that I do it now, because I'm lame Win user :) but no worries. Btw the asterisk problem can come even from xwindow service and impact Eclipse itself not specifically Scala IDE.
