Hi
Could you try with 2.0m3 there was a fix in the simple language in
relation to use ' ' in the left hand side.
You can also try other combos
${in.header.type} == TYPE1
${out.header.type} == TYPE1
Just to see if you get a match.
If still an issue let me know and if you can create a sample / unit
test that demos it then I can take a look and debug / fix the issue.
