Forum OpenACS Q&A: Re: Forums (HEAD): error when posting

Posted by Gustaf Neumann on
I have a short break between two seminars, and fixed the issue above in cvs head.

Btw, the problem is not precedence, but double evaluation, where an empty string resolves in the second evaluation into nothing. expr does its own eval.

The error shows up on:

set x [expr "" eq ""]
