Hi,

I've tried installing the Ruby Development Tools for Eclipse twice and almost immediately upon typing I receive an message saying "An internal error occurred during decoration calculation". It's serious enough that I am totally unable to do any development with the Ruby Development Tools. Does anyone know a solution for this?

Thanks for any help.

Hi Steve,

Could you please check if something meaningful is reported in the ErrorLog view? If some exception happens it should get logged.

It's hard to say what happens without any details.

Regards,
Alex

I am also getting the same "Decoration Calculation" error.
Looking in the [workspace]\.metadata\.log the Stack Overflow error is caused be caused by a recursive call to: org.eclipse.dltk.internal.core.util.MethodOverrideTester.fin dOverriddenMethodInHierarchy(MethodOverrideTester.java:118)

Here's that contents of my log file:

Hello,

i have the same problem after installing the Ruby addon to eclipse:

An internal error occurred during: "Decoration Calculation".
java.lang.StackOverflowError

Is there a soultion in between or do i need to look for a other editor for Ruby ?

Thanks in advance.
