Hi!,

I'm working with lessonbuilder and I did a new page and it worked fine. I
had not worked with it for some time, and now I have an error when I try to
do something with any button. The error doesn't show anything about
lessonbuilder code, so I don't have idea about it, Can you help me please :(

The error is:

2014-06-20 16:39:27,676  WARN http-apr-127.0.0.1-8080-exec-1 PonderUtilCore
- Error invoking action
