Description

In the past, we already encountered issues with special tokens on transformapply where the token included the delimiter between token and code. A similar issue still exists for transformdecode which causes failures similar to the one below:

Caused by: java.lang.NumberFormatException: For input string: ""

This task aims to fix this issue and create global consistency for all construction and splitting of recode map entries.
