Docker container with tomcat and ASCII-Art output throws exception with activity beta input. #96

Open Boldie opened 5 years ago

Boldie commented 5 years ago

I tried to create ASCII-Art with the docker container / tomcat. I got an exception instead of meaningful output:

Recently found out, the official server also will throw the same exception, so it seems to be a Bug related with the new activity syntax and Plantuml in general.

arnaudroques commented 5 years ago

The real issue is that export to ascii-art is not implemented for activity diagram yet. This would need some important work to make it work.

I found this out too :) Maybe there shall be a warning or something instead of an exception where nobody knows what went wrong.
