Subject Re: How to use string functions from ruta-core-ext in Ruta
Date Wed, 18 Nov 2015 08:26:34 GMT

I must admit that I did not realize that this is an example from the
documentation. This is either a good sign that there are many examples
or a bad one that I do not even know what is documented... I am afraid
that this is not the last error in the documentation, but we work on
improving it steadily.

Thanks for poiting it out! I fixed it :-)

Thus,  the substring from 0 to 8 returns "Alexande".

reality, however, nothing happens. I get no error message, but after execution, there is no
"Test" annotation.
