What version of matlabcontrol are you using?
(Release versions: 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)
4.0.0

What version of MATLAB are you using?
2012a

What operating system are you using?
Linux

Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Inside matlab

What steps will reproduce the problem?
1.
2.
3.

What did you expect to happen? What happened instead?

Please provide any additional information below.

Sometimes matlabproxy.eval(cmd) runs the command inside a method namespace 
instead of the main namespace. This happens in a gui matlab application, and 
I'm guessing it's related to callback functions. I expected this to not be 
possible due to matlab's single-threading, but I can see it happen occasionally.

Anyway: Replacing "eval" with "evalin","base" in the three relevant functions 
of JMIWrapper.MatlabThreadOperations seems to fix it.

Sorry, no. It was (is) a race condition, and not easily reproducible. The 
application where it happened is a matlab gui (java driven) application, and 
receives user events simultaneously with matlabcontrol commands. I have not 
seen the problem since replacing eval by evalin.
