Exception in Netbeans when stopping at breakpoint

Exception in Netbeans when stopping at breakpoint

[os97673]

could you please try to run ruby debugger in verbose mode and provide its output

[MatsGard]

Yes, but how do I run ruby-debug-ide in verbose mode?
I run my application from Netbeans.

[os97673]

Unfortunately I'm do not know :( I'd suggest you to contact Netbeans' team

[os97673]

you need to pass "--debug" argument to rdebug-ide somehow

[MatsGard]

I have tried to uncomment in ruby-debug-ide-0.4.23.beta1/bin/rdebug-ide:

opts.on("-d", "--debug", "Debug self - prints information for debugging ruby-debug itself") do

Debugger.cli_debug = true

end

But I can't see anything other than the normal stuff in development.log, perhaps it logs somewhere else?

I also sent an error report to Netbeans and perhaps their answer can be a lead:
"User Comments:
dkmd_nielsen: Attempting to debug into a method by calling the method's alias
name. It's been a while since I've encountered this error. The method is new.
The project just initialized a Mercurial database. These module changes are
not yet committed. There is nothing really new about this project I'm working
on, except the above.

GUEST: Waiting for variables to display"

Now it worked, the following is logged after stopping at a breakpoint, when I switch to the variables tab:

We have extended the protocol (variable node contains value sub-node) which is supposed to be compatible from xml point of view but debugcommons (which is used by Netbeans) is not prepared for this change. So you should either use 0.4.23.beta1 or ask Netbeans team to fix debugcommons (I will be happy to help them if they need such help)
